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.
Yes. Our universe started as a size of our hands, then the size of earth. Then became HUGE
What reasonable estimate for the size of a cell's nucleus?
The observable universe is constantly expanding due to the ongoing expansion of the universe. This means that the size of the observable universe is not constant and will continue to increase over time.
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.
At present, the size of our Universe is unknown. Because light can travel no more than about 300,000 kilometers per second, and because light has only been traveling to us since the time of recombination; there is a limit on how much of our Universe we can see. How much larger is our Universe, beyond what we can presently see, is a matter of speculation.
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.
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.
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.
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.
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
They used a method called "representative sampling" to obtain their estimate. The sky is divided into sections of equal size and the number of galaxies in one section are counted. The count from that one section is then multiplied by the total number of sections in the sky
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.)
The Universe is expanding, so its size is increasing.
Yes. Our universe started as a size of our hands, then the size of earth. Then became HUGE
The no. of atoms in the Universe is not estimated yet because till now we are not able to calculate the amount of matter present in the universe and what is the exact percentage of each element in the universe. Once it is calculated, scientists would be able to calculate the no. of atoms in the universe.
that is unpredictable. cause we cant find 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.
