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
