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.

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)
How big is the existence?
The scale of existence is vast and encompasses everything that we know of in the universe, from the smallest particles to the largest galaxies. It is difficult to quantify or measure the size of existence as it extends far beyond our current understanding.
What is the process used by astronomer to estimate the number of galaxies in the universe?
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
Put theses in increasing size. Andromeda galaxy Earth Sun Universe?
Earth, Sun, Andromeda galaxy and then the universe. increasing size------------------------->
How deep is the universe?
From our perspective the most distant galaxies we can see in any direction are roughly 20 billion light years away. The precise topology of the universe is not really that of an expanding sphere. There may well be nothing--not even nothing--beyond the "edge" of the universe.
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 can we estimate the size of universe?
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.
What is the estimate current world population size?
4.3 billion
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.
What is ten to the twenty-third power?
A very large number. One and one half times ten to the twenty third power is the current estimate of the number of stars in the universe! There are 500 billion stars in our Milky Way galaxy and there are 300 billion galaxies in the universe by the current estimate. If all of the other galaxies are the size of the Milky Way galaxy then the total number of stars is 1.5 times ten to the twenty third power!
Does red shift expand 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)
How large was the universe when the sun and solar system formed?
The universe was already vast when the Sun and our solar system formed about 4.6 billion years ago. The exact size of the universe at that time is difficult to quantify, but it was significantly larger than the scale of our local solar system.
How do I estimate a woman's dress size?
It is very difficult to estimate a dress size, especially online. You may want to consult with a close friend of hers, check in her closet, or take her shopping with you. She might appreciate the quality time.
How big is the existence?
The scale of existence is vast and encompasses everything that we know of in the universe, from the smallest particles to the largest galaxies. It is difficult to quantify or measure the size of existence as it extends far beyond our current understanding.
How big will the universe be in one trillion years?
The concepts of size, age, and shape for the universe are really unknowable. We can only estimate upon the observable portion of the universe. Additionally, even the current size of the observable universe is based upon calculations for our centric position within a sphere, but there is really no way of knowing the shape of the universe. Additionally the evolving expansion of the universe provides for disparities in the actual sizes of astronomical bodies as the universe expands over time. Considering that the universal expansion is accelerating with time, this implies yet another level of complexity for such estimations. Since the answer to this question is really subjective, based upon the assumptions made for measurements, the answer is more of a classroom issue from which these assumptions have been quantified.
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.
