Currently we can't. It seems quite certain that the Universe is, at the least, several times the size of the OBSERVABLE Universe. However, this is just a lower bound, and the actual size of the Universe may be anywhere between that, and infinity.

Is it true that your universee is inside a universe?
Yes. Our universe started as a size of our hands, then the size of earth. Then became HUGE
What is a reasonable estimate for the size of a cell nucleus?
What reasonable estimate for the size of a cell's nucleus?
Does dark energy affect the size of a universe?
Yes. Due to dark energy, the Universe is expanding faster and faster.
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 relationship between all matter and atoms?
In a way, matter makes the universe. The mater in the Universe determines the energy and size of the Universe.
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.
If the universe is infinite then why are there a finite amount of galaxies?
It is not yet certain what size the Universe is, not even approximately - but it is probably not infinite. If you have seen an estimate about the number of galaxies in the Universe, it probably referred to the OBSERVABLE Universe, which is definitely not infinite.
Is the size of the universe falsifiable?
Yes, the size of the universe is absolutely falsifiable because the universe has not been accurately measured. Once the universe is accurately measured, it will be much more difficult to falsify its size.
How the size of the universe changed not the size or mass of the earth JUST the universe?
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
How many black holes do scientists estimate can be found in the universe?
Unknown - As they can't easily be detected, and most of them are expected to have been formed upon the onset of the Big Bang. Astronomers estimate that in our region of the Universe, there are some 100 billion supermassive black holes. But this does not account for the lesser size black holes, of which there is estimate to be a much larger number.
How many atoms are in the universe?
The visible universe is estimated to contain between 1078 and 1080 atoms.(One estimate at the higher end of the range is 4 x 1079.)This is the estimated number of atoms in the observableuniverse, but since we do not know the absolute size of the universe, we cannot be certain.(Most of the matter in the universe is still hydrogen.)
Does red shift expand the universe?
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then (size of universe at redshift z)/(current size of universe)= 1/(z+1)
Does the universe increase?
The Universe is expanding, so its size is increasing.
Is it true that your universee is inside a universe?
Yes. Our universe started as a size of our hands, then the size of earth. Then became HUGE
What percentage of the universe has life?
that is unpredictable. cause we cant find the size of the universe....
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.
How old do scientists think the universe?
They estimate the age of the Universe in more than 12 billion years.
