Seminars' Highlights
Day 1: Friday the 6th November SEMINAR 1: William Metz: Vino Premio Award (2014) Terroir Analysis with drones (Final report) Born & raised: California/Switzerland. Also winemaking background/studies. William won the VDEWS scholarship last year for this project. Since then working with 15 different producers, 3-‐4 visits/year. 200 flights. Germany, France, Switzerland: Trimbach, Loosen, Dönnhoff, Montrose, Lascombes, Faiveley, DRC, Liger Belair, Rousseau, Ch. Charles, Ch. Candale, Domanine de l’A and more. Using a “Sensefly” drone. Route of drone planned on computer; not controlled manually. 40 min flight time on average. Why use drones? Viticulture is a continuous series of observation and reaction. UAV’s are good at spatial observation.
What can a drone help with in viticulture? “Precision” viticulture. Collect data in vineyards, evaluate, and adjust actions for specific vineyards/terroir.
Mapping soil and geology, grapes (plants). Precision of 2-‐5cm/pixel pictures. Software stitching together pictures from various flights/pictures creating a complex map. Useful for observing/adjusting:
• Growth cycle, photosynthetic behaviour. • Vigour • What parts of a given vineyard are performing the best. • Irrigate/fertilize smarter. • Track virus movement through vineyards. • Erosion risk. • Differences in soil, nutrition, available water etc. • Both physical measurements and 3D measurements like sun-‐exposure e.g.
How to use collected data:
• Tie knowledge to timing/cycle of grape vine. Adapt data to different times of year/cycle to know when to do what.
• Harvest planning. (Also for logistical concerns: best use of equipment, workers, tanks, press etc. optimise via planning of what to pick when)
• Zoning of vineyard. Selective harvest. Data from drone combined with (traditional) analysis of grapes gives high precision.
• Monitoring vintage differences and adapt actions to specific vintage. • Combine with soil samples for in-‐depth/detailed map and understanding of
vineyard. • 3D mapping of vineyards. (Also to show consumers for promotional purposes). • 3D model combined with solar simulation. (How much sun are different spots of
vineyard really getting) What time of day/year. How many sun hours/days a year. Combined with weather data.
• Data to use by producer on app. You can literally walk in vineyard and it gives you accurate data of the spot where you are standing. (Vines and soil)
Conclusion: easy to gather data from drone. The analysis is the challenge. Key is to validate and calibrate findings with “traditional” ways of gathering data. Good results with zoning of vineyard and harvest planning. Q: what are the costs involved for the winery? A: not yet a commercial project. Still to be calculated. Future: highly timesaving for producers. Comment: future plans to create company that offers these services to wineries. Q: who owns data? A: the winery is the owner of the data. Comment: Possible to add camera to tractor to add further info about yields etc. This would add another layer of information.
SEMINAR 2: Alexandre Schmitt: Wine and Flavors (400 aromas usually in a wine) Alexandre is a “nose”. Experience from the perfume industry. The sense of smell. There is no such thing as a smell. It’s your perception. Your own realm of senses. The analyse of smells: Recognition, pleasure and comparison. When you smell something your brain compares it to a memory of a similar smell. Your memories are unique and therefore your perception of a given smell is individual. “The subjective element of perception” Adapting this to wine… Why do we speak so much about wine? How come this abnormality of discussing wine more than any other thing? Why can we speak for hours about wine and not anything else? We all suffer from the addiction of speaking about wine; a need to speak about wine. Because it encompasses our senses, memory and emotions. Not just aromas, but also textures when we speak about wine. When we think about pear e.g. it is not only the aroma itself but also the juiciness. Can we smell analytically? Can we translate our subjective perception of a given smell into something analytical, that we can all understand and agree on? Can we define a smell? Our memories of a given smell are intimate, private and highly subjective; how can we translate this into something common and definable? We can train ourselves in speaking the same language. Training in how to describe and define aromas. We can all learn the “language of aromas”. Just like learning a new language, we can learn to speak the language of aromas; learn to define aromas. Any aroma is an image. The context is the wine, the medium.
There are 2 ways to discuss wine; the subjective and the analytical. The aromas: apple, peach, caramel et are subjective images of memories and impossible to analyse, how many molecules of apple? Impossible. The image of apple aroma is something you create yourself. But, we can define certain molecules existing in grapes and these can be explained. These molecules in combination give us an image of an aroma, like e.g. apple. This is the analytical language of aromas. All senses work together; not only smell. Your “result” of a wine is a combination of all senses, even if you concentrate on the nose only. The olfactory sense only makes up a minor % of the entire perception. Vision is today by far the strongest and most used sense for man. When man changed from crawling to standing up, became homo erectus, nature started favouring the visual sense. Before the olfactory sense was favoured. This is a part of the human evolution. It was the evolution of the species that favoured vision over small and taste. We have more words about visual descriptions then tactile, olfactory and any other sense. In any language there are more words to describe what we see than what we feel, see, taste and smell. Visual: more than 20 words in English. Touch: maybe 5. Taste; sweet, sour, salt, bitter. Smell: not only one! Only analogies. How to objectivise the subjective perception of a wine? Sensory experiment. All participants are given an aroma sample and have to note down some words that come to mind. (Below my personal perceptions, the actual aroma noted in bold) 1: wood, resin, rosemary. Pine. Cedar. Words used both fall into categories of dry and fresh. (aromas can also be confused with the dryness of tannins)
2: Eucalyptus, camphor, menthol. Lavender. Honey. Resinous. Aromas: only in the category of fresh. 3: Caramel, candied orange. Vitamin pill. All references relate to something sweet. Can we smell sweet? It is resin of a South American tree. Balsamic. 4: Brown syrup, caramelized sugar. Vanilla. Brown butter. Animal. Musky. Sweat of an animal. Leather. Balsamic. Tobacco leaf. Toast of oak. Vanilla extract, Madagascar. 5: Vanilla. Sugar with vanilla. Lighter purer less pungent vanilla. Powdery, sugary. Almond. Synthetic Vanillin. NB; synthetic flavours are created by human and does not exist in nature. 6: Orange peel. Orange juice. Acid, bitter, fresh, sweet, soapy. Green Indian orange. NB; the combination of acidity, sweetness, bitterness and salt = balance, also of aromas. A natural balance between elements that complies not only for taste. Humans have a natural affinity for sweetness, as our mother’s milk is sweet. We gradually grow away from this with age but unconsciously sweetness = comfort and safety. (If you had a good, safe breastfeeding period you like sweet. If you had a dramatic breastfeeding period you hate sweet). Bitterness is a very refined taste. To like and enjoy bitterness is a highly refined thing. More refined cuisines like many Asian use much more bitterness. 7: Mandarin peel. More metallic, petrol, bitter. Madarin Nb, mandarin is the original, clementine is a manipulated version with less seeds. Real mandarin has a lot more complexity and bitterness. More vibrant. NB. we THINK that mandarin and orange are similar because they look the same. Again, the visuals dominate our perception. Smell is very different. Tasting of a wine to adapt new sensory knowledge: 2011 Chateau Guiraud. Vanilla, caramel, honey, a fresh resinous note. Patisserie. Wood. Floral notes, peony. Apricot. Spicy (white pepper). Round and quite rich on palate. Opulent. Juicy, then very spicy. Lots of pleasant bitterness in finish that balances the wine up together with the acidity. Sweet notes from oak in the aftertaste. Fresh versus dried fruit: Oxidation changes the whole spectre of aromas completely. A fresh prune versus a dried one do not share any similarities. Different universes of aromas. Pineapple note is usual found in dried white grapes.
SEMINAR 3: Claude & Lydia Bourgignon, Terroirs and Soils What is terroir? Composed by:
• Climate (man is slowly changing this). Climate has to be mild. Varieties adapted to climates. (Pinot Noir = Burgundy / Grenache = Spain)
• Topography. Dry soil heats up quickly; wet soil heats up very slowly. Rainfall can be managed; Bordeaux drainage as example.
• Geology: Rock structure. Horizontal/vertical rock structure. Type of rock, adapted to different varieties. Poor/rich in minerals.
• Soil: bio diversity, structure. • Varieties: varieties adapts to specific terroirs, Planting density. Pre-‐phylloxera
very high density was the only way to avoid diseases as there was no spraying. Example: Burgundy 24.000 plants/HA then; now 10.000. Same picture in other regions.
• Training of wines: also adapted to terroir/climate to optimise. • Grafting according to soil type. • Cellars constructed of same stone as in vineyards = harmony. Wines grown in
limestone should be made in limestone cellars etc. = Vin de Terroir. Biological dimension of soil: TOP LAYER: Fauna = eaten by small animals/insects/mites/worms/ = creating humus. (4 billion live individuals/HA) They make an airy, light and water absorbing soil structure. Soil should be aerated; roots go deeper, water is drained, soil is heated.
Texture of soil. Importance of structure of clay. Stores silicate and aluminium in the surface. Therefore we should never destroy the superficial layers. (But yes the superficial roots as the plant go deeper = old philosophy to improve quality.) MID LAYER: dead roots inhibited by mites etc. This allows deeper roots to flourish and also the creation of new roots. Worms are of great importance for working the soil as they transport structure and nutrients between the different soil layers. Today roots stay in surface as soil is destroyed. Today usually only go 50cm deep; before 2,5m. If there are no herbs on surface, roots stay in surface as there is no competition. Vertical roots are very important for the quality and longevity of the vineyard. Importance of fungal bodies; mushrooms and mycelium as they create antibiotics that protects the plants and help them live longer and better. Microbes: without microbes the plant cannot absorb nutrients; Nitrates, sulphates and phosphates; via oxidation or chelation. We have no expression of “terroir” without a live soil. It is the microbes/fauna that aerates the soil. (We are destroying this with chemicals and mechanical work) The plant also lives on air = photosynthesis. Carbon, Hydrogen and Oxygen. Canopy creates sugar/alcohol. Cofactors (zinc, potassium, iron etc.) and enzymes. This is what makes your soil different from the neighbour. So Terroir is the life and processes of our soil. Quality/type of clay/ not quantity of clay. Internal surface of clay binding minerals. Deciding what varieties perform best. Great internal surfaces : red wine Small internal surfaces: white wine Analysis of clay surfaces: outer surfaces are homogenous, internal surfaces are not. Even within Clos de Tart where they made a study there are great differences of clay structure in different depths and parts. Clay with a larger internal surface has a much larger capability of feeding the plant and therefore producing great wines. This knowledge can help us understand where great wine really can be made. We also need to use rootstock that matches the soil to ensure proper feeding of the plant. This was also proved in other regions through studies; amongst others in Champagne and at Pingus. Studies prove that clay forms a much more important role for quality than formerly regarded. We see that this must have been the explanation why some varieties are planted where they are. It really makes a huge difference. Many Italian terroirs have a high content of magnesium = pleasant bitterness in taste. Most terroir typicality’s have an explanation in soil structure and contents.
SEMINAR 4: Sylvain Pitiot: Cartography of the Burgundy vineyard ClimaVinea app Digital app dedicated to wine lovers; mainly Burgundy lovers.
• Showing maps and all details of vineyards. All his work compiled in one app. 1400 “climats”.
NB: Un climat: in Burgundy sense: a notion of parcelling.
• You can geo-‐localise where you are and get info about the vineyard you are standing in.
• Contains a “who’s-‐who” of Burgundy. 132 elite estates and negociants. Selected via a cross of 3 great journalists including Steven Tanzer and Michael Bettane.
• Encyclopaedia of Burgundy as region; history and culture. Explaining history of names of climats.
• Vintage charts and price statistics for each wine. • Strong searchable technical database.
It is an interactive application made for both wine lovers, journalists, traders, sommeliers etc. Only available for iPhone at this moment. Soon for iPad and Android.
-‐ App can be personalized, font, background, language. -‐ first of all an app for mapping. -‐ All history and legal data for all climats. Yields, alc % etc. -‐ Origin of name and history of vineyard. -‐ What producers produce from the given vineyard.
-‐ Contact details. -‐ All wines produced. -‐ Shows correspondence between Lieu-‐Dits and Climats. -‐ Under all climats/lieu-‐dits: list of producers. -‐ List of producers where you can buy wines directly at the chateau. -‐ Presentation of wine critics specialising in Burgundy. -‐ List of recommended literature and web sites / blogs -‐ Mini encyclopaedia of words, terms, definitions. -‐ Climatic info. -‐ Technical wine info (fermentation etc). -‐ Searchable database with tons of cross-‐references. -‐ For Grand Cru vineyards ALL producers and wines included. -‐ Extraordinarily detailed info on grand cru vineyards and climats. Really a complete Burgundy book and guide digitalised. Plan to complete Burgundy with Chablis, Cote Chalonnaise etc before other regions and countries, but possible with a more global future of the app.
Day 2, Saturday the 7th November SEMINAR 1: Round table. Great wine and the digital revolution Antonio Galloni (Vinous), Eric Levine (Cellartracker), Severine Bonnie (Malartic Lagraviere), Paul Roberts (Colgin), Patrick Bernard (Millesima), Olivier Duha (Webhelp). Moderated by Pascal Cagni (former CEO of Apple Europe). Intro by Francois: The world of wine is changing with the new tools of communication. How does it affect us and how do best possibly adapt to benefit from the innovation? Severine Bonnie: Small family owned group, originally from Belgium. Bought Malartic Lagraviere. Then founded DiamAndes and bought Gazin Rocquencourt. Increased focus on digital communication. Pioneering at re-‐wamping web sites for new tablets/phones. Social media as part of communication. (Facebook, Twitter, Weibo, etc) Chinese person dedicated to control Weibo. Family has always focused on communication and uses very little paper-‐based advertising. Communication is done separately and differently for all 3 properties according to strategies and markets.
Paul Roberts: Colgin’s 23 years of history. Unique focus on hillside single vineyards with distinct identity. Freshness, structure and Napa fingerprint. The possibility of selling direct:
2/3 sold as futures directly to end consumers in 22 different countries. 1/3 is sold through traditional distribution around the world. The direct sales create an opportunity to communicate direct with most customers twice a year and this creates loyalty. But how do you stay relevant to your trade as a small producer? By working as direct as possible, also with trade to ensure that Colgin as brand is communicated as optimal as possible. Large investment in the digital platform/univers/world has been done. Web-‐presence is very strong. Social media: high focus on how to ensure communication in the right way. How do you translate philosophy into social media? Matching style of wine/property with marketing. Use of visual material more than words to show the “romance” of what they do. Patrick Bernard: 1993 he founded Millesima. Not a background within the wine industry. Basics: Based on marketing and not normal commercial approach. Ensuring top quality and provenance. Bought directly from estates. Mailing lists and catalogues, internet site. Problem is that digital communication is easily “cold”. Therefore they have female sales representative to handle male French customers and in the UK men handling female buyers. Adapting sales initiates to the given countries/buyer patterns. Started with only Bordeaux, then adding Champagne and Burgundy. 1997 crucial year = first website. Within 6 months = 6 websites, 6 countries, (even 48 states in the US). Today a total of 16 websites. Each 3rd year they discard/re-‐vamp one website to remain up to date. Trader; but also media/communication. Internet allows opening globally. 3 million visitors online/year, but always combined with more personal sales. 80% internet, 20% personal. Lots of contact/sales via FB. 24.million interactions via FB. 90.000 customers in 120 countries. High focus on customer satisfaction even when online sales. Eric Levine: Background at Microsoft Office. (He developed the “report a problem”/crash for Office to gather data and eliminate crashes) Went on a trip to Tuscany: eye-‐opener for wine. 2003: started collecting wine. Kept in an excel file. Wanted to make better order in his cellar and tasting notes to keep track of wines tasted. He created his own database on the web for private use. 2 friends wanted to use it as well = business idea was born. CORE: Gathering voices and opinions. Cellartracker: tool to let a collector catalogue their cellars. Today 400.000 users. 63mil bottles tracked totally. Any size of collectors. Choice to share reviews of wines if you want. 5 mil wine reviews 2015.
There is a continued growth of wine related, specialized tools and also digital communication in general. People connecting to share/get information and to buy and sell. Antonio Galloni: Early exposure to wine as a part of a meal, but also to truly great wine as his parents had a wine store selling Bordeaux/Italian wines. He was early drawn by the complexity of wine world and had a wish to understand and learn all with a perpetual focus on open-‐mindedness. (Living by the motto from his music teacher: “You must listen to music you do not like one day a week”). Looking for quality everywhere. Great wine can be produced everywhere. Looking for the pinnacle across styles. “Quality is vertical, excellence is horizontal.” He went into finance to get a real job and was re-‐located to Italy where he started tasting/taking notes. Soon friends started asking to read his notes. Went to business school at MIT. (Contacts from there is behind Vinous)
• 2004 first newsletter. “The Piedmont Report”. • Parker offered him a job at WA • Left WA to start Vinous 2,5 years ago. • Bought Tanzer. • Today: Paying subscribers in 80 countries. • Mapping project with Google. • 16 employees. • Partnership with Wine Searcher and Cellartracker. • High investment in keeping the digital level up to absolutely newest
technology. • App on the way.
Olivier Duha: Running a company that helps companies/brands with their web presence. You can no longer lie to your consumer. Internet = transparency. You need to keep customers happy. They can easily destroy your image. Today a highly increasing investment in social media across industries. Communication is publically visual. (FB, Twitter etc ) We have passed to remote contacts (bank, post-‐office etc) Apple as example: incredible customer in service in shops. Online store is highly different = cold. This will change; adding personal “warm” service online. NB. Actually 15% of all transactions on Amazon require personal contact. This will have to be increased to maybe 45% or more. We need to personalize the digital world. Consumers want the combination of the 2. Vivino as example. Empowering wine consumers to share their thoughts through “personal” recommendations. Newly added purchasing function so you can follow the entire value chain. There is however a lack of “certification” of points and opinions. How can we trust others assessment? Need for “Certified wine amateurs”; a global panel of trustworthy tasters/ communicator. Comment: Parker score correlates with average 30 Vivino users, so how needed is this kind of certification at all? Private sales – more direct, more open, more personal communication. The consumer can become ambassador. The power of the consumer is increasing. We can do most ourselves. How do companies handle this? High importance of maintaining value digitally. Example: The reason Amazon is not making money is that people do not love Amazon, people love Google and most traffic to Amazon goes via Google searching for a given product. Pascal: Massification, globalization, emerging markets. How do we reach out? We are entering the bronze age of the Internet. 11,5 mil apps existing today. 300.000 labels scanned a day on Vivino. (500.000 users) How do we monetize informative apps? (Purchasing options on apps like Vivino) Severine: (Why do they not work directly in Bordeaux?) In BDX working through trade, fixed existing system. Distributors with long-‐term loyal customers. In Argentina more direct. Adapting sales channels to markets. Paul: (Why do they focus on direct sales?). In the beginning they had very little wine, making them not interesting for a distributor. Hands-‐on sales via phone/fax. Today more Internet based. Individual customers: privates, restaurants and top retailers. They DO work with the traditional trade to build brand and awareness, but want to have the direct contact to all customers, globally. One-‐on-‐one customer contact ensures loyalty. Financially
more viable to sell directly as margin is higher for the producer, but the trade is an absolute key to remain relevant globally. Use digital strategy in combination with the trade to create image. Multichannel approach. (Omni-‐channel) Eric: The majesty of wine is its incredible diversity. The challenge is also its diversity/complexity. Can seem scary. Having quality filters when creating and sharing information is highly important. Pascal: Do some people only look for info or both info & purchase? Why doesn’t e.g. Vinous also offer sales of wine (huge market)? Antonio: Vinous as defensive business. Stabile, sustainable safe cash-‐flow. 90% renewable subscriptions. Total independence, therefore no ads nor sales of wine. That is the reason for NOT wanting to sell wines. Focusing on growth in different and more sustainable way. Producers wanting to take control and severity of own brand. Getting closer to consumer, knowing their customers better. Therefore direct and/or recommended sales are increasing.
Antonio: Latour bought Araujo to get a channel to sell direct. DRC sells direct; as customer you sign an agreement that you will not resell. You MUST know who your end-‐consumer is to be able to do this. -‐ Vinous also want to be close to subscribers. Post something new valuable every day. A digital eco-‐system. A digital value-‐chain of information. “My dream is to walk
into a great restaurant and see a great bottle of wine on each table”. This should be our common goal. We should remove mysticism about wine. Make it more approachable. There is no competition between apps/ etc. They compliment each-‐other. Think about the big picture. Pascal: Publishing business like Vogue are now interested in creating a marketplace. They reach 500mil readers, they can offer any brand featured a great direct access to consumers. Wish to start selling to readers.
Patrick: Theory of archipelagos. Remember; BDX 17th/18th century trading system set-‐up. 70-‐80% production is sold on one day. (total of 500 traders). It is a really efficient system, a strong set-‐up that is on the way out of 3 hard years with vintage 2015 soon to be out. –It is difficult to be good at both producing and selling. You have to create partnerships and do what you are best at. This creates a need for the trade. Consumers traditionally did not accept recommendations from traders/producers as its too direct and impartial. There is a lack of credibility when pushing products. We should not mix the roles. Producer, trader, journalist = separate. Using friends recommendations is the most reliable source for most (FaceBook is today’s way of doing this) Internet is creating transparency globally for pricing. Pascal: “map” / value chain is becoming more complex with the blogosphere/social media.
Olivier: we can easily process the information we need. Personalized information. This is key for marketing. Empowering any consumer. Personalization in marketing enables to think before the consumer. Accumulate data/knowhow about your consumers. Predictive marketing. Work in advance of the consumer to be able to offer him/her the right thing at the right moment. Pascal: Shared economy: could this apply to private cellars and producers? If you have wines/bottles/overstock that you wish to sell… Eric; has been tried without success. Patrick: no threat from “re-‐sellers” as provenance is key. We should never buy from customer’s cellars. Wine should not be object of speculation. Parker created this… Wine is made to be drunk (and pissed)… This allows us to open a second bottle and ensure a healthy market place. Wine is to be shared with a story. All good with technological advances, but its still wine we are dealing with. Pascal/Olivier concept of subscriptions. Example of value added Internet sales: Monthly packages of wine, sent out. You can select your price level and subscribe to monthly cases of often unknown, smaller wines. Helping producers sell and consumers to discover new wines. Ease to market on Internet. Adding value to sale
for both producer and consumer. (You pay a subscription fee to have access to these offers) Paul: Internet has changed trade. Before you “subscribed” to a given retailer you trusted. You trusted his advice. Scalability is de-‐facto to all we do. Not about making more but making better and deeper business and relationships. You are much stronger if your sales do not depend of points/ratings but on loyalty. We use digital technology to better communicate what we do and to sell more wine. Pascal: our abilities to reach out into the market have (and are) exploding. Future will continue. We can reach out directly to a very larger customer base. Q: (to Patrick): how do you ensure provenance and traceability? A: Traceability is to fight fraud. There’s lot of new ways to ensure provenance. Chips, numbers, etc. “eProvenance”, but they are expensive to apply. It is however interesting as it enables to track both temp and position of bottle. It could be a good way to keep in contact with end customer and also know more about them. Pascal: New less expensive technology is soon there to solve this. Problem is currently that these chips require energy to gather and store data over time. Severine: eProvenance is too expensive. Adding 3-‐4€/bottle and only viable for very expensive wines.
Francois: huge problem today of knowing where your expensive bottle has been traded and how its been stored. Especially with world opening op and more wines
being traded internationally. We need and want a guarantee when buying expensive/rare/old bottles. Pernod Ricard : All their products sent to Asia the past years are traced. Note: We are here only speaking about the elite of the wine world. The world is more segmented than this. It’s not only about personalizing relations with one single customer, but also doing this on a larger scale using modern technology. Olivier: Not “one” uniform market. A huge variety of wines sold and ways of selling in totally different markets. Each a very different set-‐up depending on the margin of wine allowing you to make different strategies and choices.
Q: Internet opens for global trade of wine and when wine travels it looses quality. Fatal for wine? A: (Pascal) you CAN transport in a good way. For wines at a certain level you can allow yourself to guarantee good and safe shipment. Ivanhoe Johnson: you can sell GOOD and quality ensured wine from a chateau to China, what is NOT good when bottles circulate the world several times. Francois: When you buy on actions/brokers you take a risk. But sometimes you can only find the wished bottle there… If you want guarantee, then buy direct. Internet: no regulation Auctions sales: some regulation, some guarantee. (But many sellers want to remain anonymous)
SEMINAR 2: From the Universe to the Planck Wall: Etienne Klein and Brian Schmidt Brian Schmidt: • Light travel from the moon to the earth: 1,5 sec. • The Sun is 8 light minutes from Earth, weights 1 mil tons more than Earth • Alfa Centauri is the closest star to us. 4,3 light years away. • The universe is full of lot of empty space. That’s why we call it space. • Our small galaxy spreads over 100.000 light years • There are 20.000 galaxies in total. • There are more stars in the visual universe than grains of sand on Earth. • 13,8 billion year is the max we can see back. …. Universe was born by the BIG
BANG. • Distances in space are measured out by intensity of light. • When light is stretched it becomes red. (Just like sounds) • The further the faster the motion away. Everything moves fast away from us. • The universe seems to be expanding • Hubble’s law: the further the faster.
• If universe is expanding now, before it was more concentrated. To a point where there was too much concentration and energy = BIG BANG:
• You run the universe in reverse = you get the time line. But gravity is slowing things down.
• Result from studies the universe is 14.000 billion years old. • Will the universe exist forever? Or start reversing again? Finally turning into
another Big Bang… • Measuring what is happening now: Continuous expansion where gravity cannot
stop it or slowing down and turning into another big bang?
WHITE DWARFS/SUPERNOVAS: • When one star collapses it gives material to another star. • When that star reaches 1,3 point mass of its “mother” star it explodes =
Supernova • Usually takes 44 days • Earth is created this way. • Supernovas are rare. Only appears every some 100 years, • We can see 500.000 light-‐years back in history to before Earth was formed. Results of recent studies: Gravity is speeding up the expansion of the universe rather then slowing it down.
So what is the explanation? Composition of the Universe: Dark energy: 70% Dark matter: 25% .
What we know = atoms only 5% Science is about making predictions… An idea that has proved itself through time. We have a battle of the future of the universe between power that pulls (gravity) and pushes (dark energy). The dark energy is stronger. This is creating more space and more universe. Unless dark energy disappears the universe will expand and disappear… Etienne Klein: Discovery of Brian is revolutionary because it revealed a different motion between atoms than usually suspected. We used to think that dark energy rotated gravity. We now know that this dark energy is made up of articles we do not know. Only 5 % particles are known. Rest is unknown matter. Why this knowledge is important to trace back to the birth of the universe? 400.000 first years after the big bang light could not disperse. It was just too dense. Light was prisoner within the matter from which it propagates so no light was emitted and therefore we have no knowledge of this period. The observable period starts 400.000 years later as light was released and propagated. In general we can still see this electromagnetical light from that period, but how do we find out what happened those earlier 400.000 years without light? The real physical laws of physics are believed not to change; despite no light. So if we recreate on a small scale a model of the universe and apply the laws of physics we should be able to see what happened during the period where no light was emitted.
• Here we need to look at astro particles /particle physics. • The Higgs boson (or Higgs particle) is a particle that gives mass to other
particles. It is part of the Standard Model in physics, which means it is found everywhere. It is one of the 17 particles in the Standard Model. The Higgs particle is a boson. Bosons are particles responsible for all physical forces except gravity. Scientists do not yet know how to combine gravity with the Standard Model.
• We have weak and stronger partical atomic forces. These are attracted by gravity. To each other and to Earth.
• This is related to Einstein’s relativity theory. • If you identify the right symmetry you know the explanation of interactions
between atoms. There are often disagreements in physics and maybe our lack of understanding of this 0 mass is not important as to Einstein: no mass = no time. Example: When girls look for husbands and men look for girls: Girls looks for men to become husbands, but men look for girls, not future wives. … This is the same analogy as universe.
Mathematics and physics do not correlate when energy becomes too strong Questions as to if the Big Bang really happened. Does the universe have an origin or not? Was there a time where there was nothing? Has the universe always bee there? The Big Bang and the earliest beginning of the universe is the easiest place to understand the basic rules.
• The rules upon which all other things are built. All biology. Quantum mechanics: static Relativity: moving.
The Big Bang might be the transition between 2 universes. A period where energy, temperature and expansion reached “zero” from reduction, before expanding again. Purpose of experimental physics is to kills ideas; to prove what ideas are facts and not. We are long way away from having the theory of everything. And if we should ever reach this point no scientist would probably ever believe this. This is not the nature of a scientist. The Universe is 4 dimensional. But we only know 3 dimensions plus time. So the universe is expanding into time. Time as dimension? There may even be more dimensions….
Multiverse? … We can only see 13,8 billion years back (our own universe). If we see behind this there are infinite possibilities. At best as we can tell the universe is flat and 1000 bigger than we can see. If you multiply infinity with infinity we get to a number of infinities that makes everything possible. The universe is probably more than 1000 times bigger than we can see. So physics change into philosophy. Nothing can be tested nor proved. There cannot be something before nothing / so if there was nothing before the big bang. Was there a time where there was nothing? By logic you cannot create something out of nothing. Q: Do scientists believe God was before something instead of nothing? A: Then you would need to define God and why and how… In a Scientist’s mind. Did physical laws exist before the universe? Or did the laws adapt to the physics of the universe. How does laws apply and connect to things? How are they created? All this is still not explained.
