What does the big bang theory tell us about current size of the universe?

Not much, unfortunately. We know that our Universe is expanding, and has been for about 13.7 billion years. The problem is, we can only see light from objects that has had time to reach us since the Big Bang. Thus, we can only know about the "observable" universe. How much more of our Universe is outside our present field of vision is still speculative at best.

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.
What was the initial size of the universe before the Big Bang theory?
The entire OBSERVABLE Universe must have been smaller than the size of a proton. Since the ENTIRE Universe is much larger, and perhaps infinite, we really don't know how large that was.
What does the Big Bang theory theory explain about the current size of the universe?
The Big Bang theory explains that the Universe is expanding. Of course, if it continues expanding, at some time it must get to be a certain size. (Note that it is not currently known how large this size is.) On the other hand, according to the anthropic principle, we must be in a fairly early stage of the Universe - while there is still lots of available energy.Post script:Absolutely right. Just a short note to say the Universe is not only expanding, but it is accelerating its expantion, due to the still mysterious «dark energy».Some cosmologists defend the hypothesis of the Universe will end in a «Big Rip», others defend the «Big Freeze».Either way, we (the Human race) will not be arround to see it...
What is a good point and bad point about the big bang theory and the steady state theory?
"Big Bang theory": * It is currently one of the better models that can account for what we observe as an expanding universe. * In order to account for some aspects of the size of the universe, we have to make some assumptions about the speed of light that do not seem to hold in the world as we now know it; in the first few moments after the 'big bang' light may have been able to travel at a velocity much greater than c. "Steady State Theory" * It was a widely held belief for centuries. * Current evidence seems to completely disprove the 'steady state' theory.
Why is it difficult to estimate the current size of the universe?
It is difficult to estimate the current size of the universe because the universe curves back on itself. (Do not ask how it curves back on itself. The equations are in the Theory of Relativity by Albert Einstein.) Since no one can ever measure the distance to an edge, no way exists to determine the Universe's size.
How the size of the universe changed?
This is true but you need to expand on what your saying it increased but the theory's from Edwin Hubble supports the information of the redshift and the relates to the expanding of the earth and the size increased in mass. And that relates back to The Big Bang theory
Is god real or is the big bang theory real?
Both of them are real. God is real and created the universe, but the Big Bang was a theory or an event that proves the formation of the universe. The Big Bang tells us that there was a state that expanded rapidly and became extremely hot. Because of its size and climate, it exploded and that proves that the planets, stars, and other things were spread out somewhere in the universe. Check the related links for more information.
If there was a big bang wouldn't there be a big hole in the center?
The theory is that there is a hole at the center of the universe, but that it is smaller then the size of an atom. Otherwise nothing is really known
What is the scientific theory explaining the origins of the world?
The generally-accepted theory is the Big Bang. In this model, all matter in the Universe was originally concentrated in a very small space, from which it expanded to its current size - and continues to expand.Actually I doubt this "explains" much; it really just describes how we observe the world to be.
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
The universe how big is it?
This is an area of active research... meaning, nobody really knows. The visible Universe has a radius of about 46 billion light-years. According to the "inflation" theory (basically, the modern version of the Big Bang theory), the total size of the Universe MIGHT be millions or billions of times bigger.
