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.
