It was microscopic. At the first moment of the bang the entire universe, that is the entire space-time continuum and all of the energy within it were spaller than an atom.

How did the size of the universe change?
In the immediate aftermath of the "Big Bang" there was rapid inflation of the universe. That slowed and the universe is now believed to be still, slowly, expanding.
Event that marks the beginning of the universe?
Current theory is the Big Bang
What did Astronomers theorize that the universe began in an explosion called an?
big bang: This is the big bang theory
How was the very small and very hot universe bubble born before Big Bang?
It wasn't. The Big Bang was the beginning of the universe; the universe didn't exist before then.
What is the Big Bang?
A theory that the universe formed in a huge explosion
How much did the universe increase after the big bang?
From an infinitesimally small point to the present size, the universe is still expanding as a result of the big bang.
What controls the size and shape of the universe?
big bang explosion
What does the big bang theory explain about the size of the universe?
Not much, really. Our Universe MIGHT be significantly larger than what we can see -- that portion of our Universe we call the "observable Universe" -- or it might be infinite. No conclusion can be made about the size of our Universe based on the fact of the Big Bang.
Was the big bang the first thing to ever happen?
In the current model of the universe the big bang was the 1st thing to happen in the universe since time itself was created in the big bang.
What is a result of the big bang?
The big bang began the expansion of spacetime with great rapidity. The Universe began with the Big Bang. In other words both space and time began at the big bang. The big bang started the Universe from the point t=0.
Was there any time when there was no universe?
No because time started with the Big Bang.
How old was the universe when the big bang thory happened?
Events in the Universe are often dated from the Big Bang. But the fact is, NOBODY KNOWS what (if anything) happened before the Big Bang. The Big Bang MAY have been the start of time itself; but it is possible that the Universe existed (in some form) forever in the past.
How do cycles affect the universe?
No. Universe A expands from a 'Big Bang' stops expanding, and contracts until there is a 'Big Crunch'. Then there is a new big bang and the beginning of Universe B, a middle, and another big crunch, a big bang with Universe C and so on. At the time of any 'big crunch', all matter and energy from that universe ceases to exist. It cannot manifest itself until after the next 'big bang', and then has no relation to anything in its previous manifestation.
When did chemical principles start?
At the time universe started: time ZERO, big bang, beginning of the existence of energy and mater.
Did space time energy preexist the BIG BANG?
Both space and time were created by the expansion of the universe following the Big Bang. Before the Big Bang, there was no space or time. Now we have space and time, and we call the fabric in which the universe exists spacetime.
What it the big bang theory?
The Big Bang Theory present the theoretical premise for the causation, termination, and continuation of an evolutionary expansion of the universe. The Big Bang promotes that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
