The limits of the observable Universe are at a distance of about 46 billion light-years. That's 46 x 109 light-years. Each light-year has roughly 6 x 1012 miles. If you multiply those two numbers, and do a bit of rounding, you get 3 x 1023 miles. Note that this is only the observable Universe. The entire Universe is larger than this, but it is not currently known how much larger.
What else can I help you with?
How many miles long is space?
The observable universe is about 29 gigaparsecs across. You'll have to convert to miles yourself.
How long would it take for light to go across the universe?
Answer #1:A long time.......=====================Answer #2:Classically, it would take(the diameter of the universe, in miles)/(5,878,464,424,000) years.
How many miles does the universe expand per second?
The universe expands 45 miles every second.
How many miles to the center of the universe?
Well, the universe never stops so... the universe does not have a center.
What is the size in square miles of the Universe?
First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known. The observable Universe has a radius of about 46 billion light-years. Convert that to kilometers or miles if you like. One light-year is about 10 million million kilometers. But the entire Universe is probably much, much bigger.First, you would measure the diameter of the Universe in miles, or its volume in cubic miles; but what would you want to measure in square miles?Second, the size of the Universe is not currently known.

How is the scientific notation useful to astronomers?
Astronomers often have to deal with large numbers, because the universe is very large and most of the universe is very distant from the Earth. For example, the size of the Milky Way galaxy on its long axis is 200,000 light years, and a light year is about 7,000,000,000,000 miles, so if I wanted to tell you how many miles long the galaxy is on its major axis, I could say it is 14,000,000,000,000,000,000 miles, or much more conveniently, I could say that it is 1.4 x 1019 miles.
How long is the universe?
indefinitely
Is universe a long U sound?
Yes, the word "universe" starts with a long U sound.
How long does it take to get to the universe?
We all belong to the Universe, so we have already arrived . .
Is the whole universe discovered?
Not every galaxy, star, and corner of the universe has been discovered, but we have discovered the universe as a whole. ------------------------- Most likely we never will since the universe is expanding at approximately 40 miles per second.
The speed of the universe is the speed of light which is about?
180,000 miles per second
What did people long ago think about the universe?
They thought the universe was a great creation by God.
