Light flows from above:
1. Down under you: a planet
2. High above you: a star
3. Way beyond you: darkness
The planet rotates in a dark space
with a bright light sourcein one direction
Why is it dark at night?
Wilhelm Olbers, 1823
Johannes Kepler, 1610
How can there be darkness in an infinite universe?
Edvard Harrison, 1984:
Dark sky because the universe had a start
Why is the sky blue?
Rayleigh scattering:blue light scattered away
from yellow and red
Does Mars have a blue sky?
Mars has a pinkisk or orange sky
The sky is blue because there is life on Earth!
James Lovelock, Carl Sagan
Joy from blue sky:
Life!
What is life?
Who are we?
We are like flows of water and fire,not like things
1.5 ton of matter goes through each of us every year
98% of our atoms are replaced in a year
Permanent reincarnation
