Right after the big bang happened, the universe was expanding at a speed of light. While it was expanding, it started to cool itself down since the big bang caused the universe to heat up to ridiculous temperature.
No. The only elements made within a few million years (actually a few seconds) after the Big Bang were hydrogen, helium, and trace amounts of lithium. Iron was not created until stars began nucleosynthesis.
Now How Would We Know EXACTLY How Big It Is And/Or Was?! We Aren't That Clever You Know! ¬¬ Go Ask Alister... The big bang is still happening today, as the universe is still expanding. So the answer to this question depends on the timeframe. The big bang is as big as the universe is today. Before the big bang when all matter was contained in a singularity it was no bigger than a few microns across. Five minutes after the big bang the entire universe was the size of a golf ball. This might not seem big after five minutes, but to go from the size of a few microns to a golf ball is like going from New York to Pluto in 5 minutes.
Yes, a blue jay named "Morty" made a few appearances on the TV show "The Big Bang Theory" as a pet owned by Sheldon.
We weren't there; NOBODY was. There was nothing at the moment of the Big Bang, and we cannot be certain of what came into existence or when in the seconds, minutes or hours following the event. So, "immediately"? We believe - based entirely on poorly-understood mathematical theories for which no practical test is possible - that "matter", in the sense of protons, neutrons, electrons, and their corresponding antiparticles, probably did come into existence within a few seconds of the event.
The current estimate for the initial expansion of the universe dubbed "The big bang" occurred about 13.7 billion years ago.
The "Big Bang Theory" may account for the events that happened during the first few seconds or minutes of the universe's existence. It doesn't purport to explain anything more recent than that.
That refers to the formation of atomic nuclei during the first few minutes after the Big Bang.
There are a few theories, but nobody knows for certain.
She missed a few episodes after breaking her leg.

The term "Big Bang" usually refers to the first few seconds - or even fractions of a second - after what is considered the beginning of the Universe. On the other hand, our Universe is still expanding - in fact, it has been observed that the expansion is getting faster.
Hydrogen and helium were the two main elements created in abundance during the Big Bang nucleosynthesis. These elements were formed in the first few minutes after the Big Bang, when the universe was hot and dense enough to support nuclear fusion.

A few minutes into the expansion of the big bang, the temperature was about a billion kelvins
