Looking into the night sky, it is quite difficult for an amateur astronomer to calculate the number of stars visible to the naked eye. With larger telescopes, more stars become visible, which makes counting impossible due to the amount of time it takes. So how do astronomers figure out how many stars in the universe?
“The first unpleasant part is an attempt to determine what the universe means,” said David Kornreich, assistant professor at Ithaca College in New York State.
“I don’t know the answer, because I don’t know whether the universe is infinitely large or not,” he said. The observable universe takes us back about 13.8 billion years ago, but other than that, we could probably see a lot more. Some astronomers also think that we can live in a “multiverse”, where there would be other universes, like ours, contained in some larger entity.
