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.

The most recent theory that upholds the big bang theory but suggests a sudden expansion after the bang is called the?

Inflation theory. This theory suggests that in the first moments after the Big Bang, the universe underwent a rapid and exponential expansion, causing it to grow exponentially in size. This concept helps explain certain observations of the universe, such as its large-scale structure and uniformity.


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 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 is the Big Bang Theory and what does it attempt to explain?

The big Bang Theory explains that the universe started as nothingness and the nothingness expanded somehow and made a big bang.that is how all of the galaxies and worlds were made. x x x xThe light distance galaxies shows that clusters of galaxies are all moving away from each other. The universe is big and getting bigger. space itself is expanding.Imagine filming this expanding universe. If you ran the film backwards. You could see how it all began. the universe once had no size at all. It burst into existence from nothing. It is incredibly hot. This is called big bang theory.:)the big bang theory explains how the universe was createdThe Big Bang is one of the theories on how the Earth was formed.


What is another theory with bigbang theory?

The Big Bang Theory is sometimes referred to as the Hot Big Bang, emphasizing its earliest condition for an existence within our traditional fourth dimensional SpaceTime continuum as a hot dense state.


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


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.


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.
