Transcript of The Big Bang

The Very Beginning The Event Proof Misconceptions The 'Big Crunch' The Cyclic Model Edwin Hubble Announced universe was expanding quickly
Discovered that the universe was finite, rather than infinite Singularities Infinitely small
Infinitely hot
Infinitely dense
Finite matter is able to squish into infinite density Space and time were created within the singularity
All we know is that we are inside it, and at one point, it didn't exist, along with time, space, matter, or us. Singularities 14 billion years ago the singularity began to expand By Joey Nadasdi and Kristin Cornies The Big Bang Theory Universe grew and cooled
Particles stuck together to make mostly hydrogen and helium
Galaxies like the Milky Way began to form about a billion years after the Big Bang After the Big Bang The theory of relativity states the universe must have a beginning
Galaxies moving farther away from each other ties in exactly with this theory Cosmic Background Radiation After glow of the Big Bang
Evenly spread out through universe
The remnant of the beginning of the universe, which was very, very hot There wasn't an explosion The singularity didn't appear in space, it appeared in nothing Prediction of what would happen if the universe were to stop
Theory of General Relativity states that the universe will not expand forever Gravity pulls on matter, which will result in the universe falling into a giant black hole The universe follows an infinite number of reoccurring cycles
Cycle begins as Big Bang, ends as Big Crunch Are we the first cycle, or the trillionth? Will continue to fall into a black hole until it returns to the form of a singularity Introduction Grew at a rate of 300,000,000 m/s, the speed of light There was a singularity, and then it began to expand very quickly After the expansion, space was created
