The universe expands 45 miles every second.
The speed of light is 186,282 miles per second.
0.033 miles per second or about 174.24 feet per second.
close to 186,000
33 miles per second = 118,800 mph
4.7 metres per second is about 10.5 miles per hour.
Well, the universe never stops so... the universe does not have a center.
The light year was invented, because, at 182,000 miles/second (9,467,077,790 miles a year), it is the fastest thing in the universe. As the universe is very huge, this is more convenient than saying how many singular miles things are from each other. Ex: 2 light years instead of 18,934,155,580 miles.
There are many theories, and the most probable one seems to be that it won't. Besides the smart-ass answer of 'the universe isn't alive so it can't die', I would say that the universe will continually expand for all eternity.
The observable universe is about 29 gigaparsecs across. You'll have to convert to miles yourself.
