How Big Is the Universe?

No one can be certain, because no one can see the entire universe. But so far, the farthest star from earth that scientists have found is about ten billion light-years away.

Since one light-year is equal to six trillion miles, then the farthest star from earth that we know about is around 60,000,000,000,000,000,000,000 miles away!

But the universe must be much bigger than that. Suppose that the earth were at one edge of the universe and the very distant star was at the other edge. Then the universe would be ten billion light- years across.

But we know that the earth isn’t at the edge of the universe, because we can look in all directions and see stars that are many millions of miles away. So all we know for sure is that the universe is at least ten billion light-years across!

  1. How big is space? Answer of question: Just at this time we are looking- location of dark energy or black body is near about 14 billion light years- yet same event or very moment, from the black body- it is again we are in the dark energy i.e. from the evolution in through telescope; looking huge universe yet- from the ultimate of philosophy; through that early- just at this time- everything in her belly. Hence, we can take the decision: big/huge space/universe yet that the case is between minimal and in your very brain. See about- Minimal Universe
