... and why it might be (not) a good thing that there

is no evidence yet...




9/35

how likely is it to find life in space

Drake Equation

N = R* fp ne fl fi fc L

N = The number of civilizations in The Milky Way Galaxy whose electromagnetic

emissions are detectable.

R* =The rate of formation of stars suitable for the development of intelligent life.

fp = The fraction of those stars with planetary systems.

ne = The number of planets, per solar system, with an environment suitable for life.

fl = The fraction of suitable planets on which life actually appears.

fi = The fraction of life bearing planets on which intelligent life emerges.

fc = The fraction of civilizations that develop a technology that releases detectable

signs of their existence into space.

L = The length of time such civilizations release detectable signals into space.

so where are all the aliens - the Fermi paradox

conflict between an argument of scale and probability

and a lack of evidence

the apparent size and age of the universe suggeststhat many technologically advanced extraterrestrial

civilisations ought to exist.

However, this hypothesis seems

inconsistent with the lack of

observational evidence to support it




11/35

explaining the Fermi

paradox theoretically

no other civilisations

currently exist

rare earth hypothesis

Its the nature of

intelligent life to destroyitself

its the nature of

intelligent life to destroy

others

human beings werecreated alone (religion)




12/35

explaining the Fermi

paradox theoretically

they do exist, but we see no

evidence

communication is

impossible due to

problems of scale communication is

impossible for technical

reasons

they choose not to

interact with us they are here unobserved




13/35

explaining the Fermi paradox by example




14/35

speculations

close encounters

UFO etc

ancient astronaut theory

conspiracy theories

nazca lines

tunguska event
