The universe is not infinite. It is 156 billion light-years wide. A light-year is equivalent to about 9,500 billion km
the universe is infinite and impossible to knowAs we understand it at this time - there is no edge.
people who study about the universe are called astronomers
There probably is no such edge. There is certainly no known edge. The "observable universe" has an edge, which is the limit of how far we can see. That's related to the age of the universe and the speed of light. Astronomers think there's a lot more beyond that limit and that the universe could be infinite in size.
Yes. To be more exact, it is "space" within the "observed universe" that is expanding. A confusing fact is that many astronomers believe the universe as a whole may already be infinite in size. This doesn't stop them saying the observable universe is still expanding. "Infinity" is a tricky idea.
Yes, there is believed to be an infinite number of galaxies in the universe.
Astronomers and physicists.
Islamic astronomers contributed to the edestruction of the geocentric view of the universe a iSlmamlhdiI.
Approximately Infinite Universe was created on 1973-01-08.
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.
That question cannot be answered. We would have to know the magnitude of every star in the universe. The universe is infinite (and expanding). It's impossible to answer your question.
They are called astronomers.
Nobody knows. They do not even know if it is finite or infinite.
