Origin of the Universe

What is the big bang theory?

• A theory that states that the universe started in a large mass and then imploded to form everything.

• A theory that states that the universe was there, will be and is there. Is homogeneous and isotropic.

• A theory that states that the universe is slowly coming back to a center.

• A theory that states that the universe started in a small mass and then expanded, the expansion cooled down the temperature and that resulted in the formation of matter, energy, space and time.

• Cosmic Background Radiation

• Static

• Singularity

How does the abundance of hydrogen and helium support the Big Bang Theory?

• Hydrogen and helium are elements on the Periodic Table

• Hydrogen and helium have many current uses today

• Hydrogen and helium are in the same ratio throughout the universe.

• Hydrogen and Helium are the most abundant element in the universe

This theory proposed that the universe

is unchanging in time and is uniform in

space.

• Big Bang Theory

• Steady State Theory

• Oscillating Universe Theory

• Inflationary Universe Theory

What is a singularity?

• An area of infinite heat & infinite gravity

• An area of hydrogen & helium atoms

• An area where stars a formed

• An area where galaxies are expanding
