The Big Bang Theory

The big bang theory describes the development of the universe from the time just after it came into existence up to today. It's one of several scientific models that attempts to explain why the universe is the way it is. It is the most widely accepted and popular theory to explain the origin of the universe. The Big Bang Theory

While many people believe that the Big Bang theory refers to an explosion, it actually refers to the expansion of the universe.

E = mc² Developed by Albert Einstein Defined mass as highly concentrated energy with c being the speed of light. With high enough concentrations of energy, that energy can form matter.

Uh oh…Antimatter! When matter and anitmatter come into contact, they annihilate each other. The existence of antimatter was first predicted by Paul Direc.

The Big Bang Timeline

Planck Epoch Time: 0 to seconds after the Big Bang. Temperature: Kelvin Size: about meters At this point in the Big Bang timeline, gravity separates from the other forces.

Grand Unification Epoch Time: to seconds after the Big Bang. Temperature: Kelvin Size: about meters Strong force separates from the weak force and electromagnetic force. (Gravity is the fourth fundamental force) Important: It was at this point that more matter was created than antimatter.

Electroweak Epoch Time: to seconds after the Big Bang. Temperature: Kelvin Size: about meters Huge expansion in the beginning of this epoch. Weak force separates from the electromagnetic force, establishing the 4 fundamental forces we have today: Gravity, Strong, Weak, Electromagnetic

Quark Epoch Time: to seconds after the Big Bang. Temperature: Kelvin Size: unknown Quarks combine to make protons.

Hadron Epoch Time: to 1 second after the Big Bang. (FINALLY, 1 SECOND!!) Temperature: Kelvin Size: unknown Existence of antimatter are cancelled out

Lepton Epoch Time: 1 second to 3 minutes after the Big Bang Temperature: 10 9 Kelvin Size: unknown Formation of hydrogen and helium starts to occur.

Epoch of Nucleosynthesis Time: 3 minutes to 300,000 years after Big Bang Temperature: 3000 Kelvin Size: unknown After 3 minutes, the universe consists of 75% hydrogen, 25% helium, and traces of lithium, boron, and beryllium. After 300,000 years, light in the form of radio and microwaves now exist.

Big Bang Visual You and your lab partner will be making a visual of the big bang and all the epochs. This visual can be a timeline, story, book, poster, advertisement, or whatever else you can think of but it must include: 1.Each Big Bang Epoch clearly labeled and the significant event that occurred in each 2.A picture to represent each Epoch 3.You must include times, sizes, or temps 4.Creativity!!! Each person/group will share their visual
