According to the Big Bang Theory, order from earliest to latest, the sequence of events that are thought to have taken place at the beginning of the Universe. If statement A is first, B is second, etc. then enter ABCDEF.

A) Inflation occurs.
B) Hydrogen and Helium are synthesized.
C) Most carbon and oxygen in the Universe is produced.
D) Symmetry of the four forces is broken and gravity becomes a separate force.
E) The universe becomes transparent releaseing the photons of the Cosmic Microwave Background.
F) Protons and anti-protons form.

Hint: Remember the Big Bang made mostly hydrogen and helium. Other elements were made latter. When annihilation and pair production of all particle is taking place, all forces will be symmetric.

Please answer only if you are 100% correct this is my lat try for this problem!

Explanation / Answer

The sequence of event that occur at the beginning of universe are DFABEC.

The process begin as follows .

1. D - grand epoch - the gravitaiinal force seprates from other force.

2. F the earliest particle and antiparticle created .

3. A -inflatiin ary epoch

4. B -nucleosynthesis - proton and neutron co.ine to form simple element like hydrogen

5 E-recombination - the universe become transparent

6. C - complex elemnt like carbon are formed from nuclear fusion of helium
