How far is the edge of the known universe from us in miles?

What you do speaks so loudly that I cannot hear what you say.

Oh, is that all Hadrian ?

Well, the age of the universe is something along the lines of between 13-15 billion years, so, take the distance that light travels in one year which equals 97761600000 miles then multiply it by (lets take the average)14000000 years =

1368662400000000000 miles

Awaits confirmation by the experts....

You're still having problems with your billions.

Taking your figures, 14 billion is 14 x 10^9.

Light travels at about 186,000 miles/second.

There are about 31.55 million seconds in a year, thus light travels about 5.87 x 10^12 miles/year.

5.87x 10^12 x 14 x 10^9 = 8.218 x 10^22 miles.

In fact, according to http://en.wikipedia.org/wiki/Age_of_the_Universe, the age of the universe is 13.7 × 10^9 years.

Thus the figures would be 13.7 x 10^9 x 5.87 x 10^12 = 8.0419 x 10^22.

About 8 billion miles (long scale – European and old English usage) or 8 trillion miles (short scale – American usage), or 8 teramiles (SI prefix).

..actually, I think the size of the Universe is about a couple of hundred miles...everything after that figure is an illusion !

Sorry, I must have been on another planet at the time.

Not 8 billion, but 80 sextillion (short), and 80 trilliard (long), or 80 Zetta (SI prefix).

First of all, sorry for posting these topics in the wrong place everyone.
My speech went down very well last night. So thanks for the help.
