Notes on space and measurement
mass cannot travel at the speed of light.
planck length = speed of light, strength of gravity and planck constant
planck length = 10 to the -35 meters
1 pl (planck length) = cell as 1 photon is to the solar system
1pl = sqr planck constant * strength of gravity / speed of light (cubed)
million earths in sun
au = 93 million miles?
voyager 150 au
22 hrs light to voyager
1 light year ort cloud?
4 light years nearest star
200 - 400 billion suns
milky way 100k light years across
Andromeda galaxy 2.5 million light years away
13 billion years to reach us on JWST
380k years after the big bang, background radiation (13.8 billion years ago)
the source of the cosmic background radiation is 46 billion light years away from us now
