Transcript of Copy of The Big Bang Theory

So that was an overview of "The Big Bang Theory"
infinite and static
agree
Physicists used to believed that the universe was has always been and always will be. This is seems reasonable, according to their observations. But this theory is contradictory to the popular beliefs that the universe has a beginning.
BLASPHEMY!!!!
Then came Georges Lemaître, a Catholic priest, an excellent mathematician and scientist, he proposed the idea that the universe does have a beginning.

Lemaitre based his theory not just on his religious beliefs, but also on Edward Hubble's discovery that the universe is expanding.

Edward Hubble
Georges Lemaitre believed that because the universe is expanding, the more back in time you go the smaller the universe is. So at one point in time, the universe was one point in space. He called that point the....
Primeval Atom
but now it's better known as...
which is a horrible name...
because it wan't big
nor was it an explosion
Hey Georges, the universe is stretching
This is evidence of God! OMG
lol, no
Beginning of Time
10^-44 sec
∞°
It's the universe, compressed into a bubble a fraction of an atom small. It's infinitely dense and infinitely hot.
So anyway, according to the "Big Bang Theory."
It's so
hot
that all the forces of physics...
gravitational force
electromagnetic force
strong nuclear force
weak nuclear force
...conjoined into one major force,
until the gravity breaks apart and
inflation
begins
This is the "singularity."
10^-43 sec
∞°
Space goes through a superfast "inflation." In a tiny fraction of a second, the cosmos expands from the size of an atom...
...to the size of a basketball.
As the universe expands, it releases a burst of energy fueling the inflation
The expansion slows down, and the cosmos cools. The energy turns into matter, according to Einstein's E=mc².
10^32 sec
10^27° C

300,000 years
10,000°C
Electrons, protons, and neutrons joined to form atoms, mostly helium and hydrogen atoms.
Light
can now shine through space.
1 billion years
-200°C
Gravity makes hydrogen and helium to form into giant clouds, which will become galaxies. Smaller clumps will eventually collapse to form the first stars.
-270°C
15 billion years
Galaxies cluster together, the first star dies and spew heavy element into space, which will create new stars and planets. This is the the universe we live in today.
We are lucky to live in this time, because as the cosmos ages and space expands, the starry night we see today will eventually get....
darker,
and darker
,
and darker...

everywhere
expansion
Now The Big Crunch Theory suggests that if the universe stops expanding, the force of gravity will....
...pull everything back together and space will end up as a singularity, and the cycle begins again.
