Big Bang Theory

what is it?

the incepetion of the universe that occured 13.8 bil years ago

Matter?

All matter and space was created

matter is moving where?

Matter is moving in all directions

reality

space itself is expanding

singularity

the single point where the entire universe started. it was smaller than an atom.

1st evidence of big bang

hubbles law/cosmic redshift: moving farther away,faster receding, more redshift, moving away

2nd evidence of big bang

the universe cooled extremely quick as the space itself expands

3rd evidence of big bang

relative abundances of hydrogen,heleuim, and other light elements

4th evidence of big bang

Galaxy evolution and large-scale structure

5th evidence of big bang

Large scale homogenity

Big crunch

gravity wins out

big freeze

expansion continues forever,most likely universe is still expanding

equilibrium

Gravity and expansion are perfectly balanced forever,universe will never end

dark matter

hidden matter galaxies that gives gravity extra space to keep from spinning apart

68%

Dark energy

27%

dark matter

57%

matter

Dark energy 

mysterious force that pushes the universe apart, causing it to expand at a faster rate

light year

how fast light travels in a year
