lolz. Just because you can't comprehend something doesn't mean it's not true. If the universe started at a point, and is currently expanding at a rate of about one million miles per hour, that means there is indeed an ending point. After the end there is nothing. We wouldn't try to get into nothing, because nothing exists. We can't exist in nothing, we can only exist in space-time, therefore we couldn't get by no matter what we did.

And lolz at the we can only see up to Pluto thing. Pluto is millions of miles away. We can see 14.3 billion lightyears away. Any farther, and the universe hasn't been around long enough for their light to get to us. (if you don'tknow what a lightyear is, it's the distance light travels in one year in a vaccuum, approx. 186,500 miles per second. It is the maximum speed anything can go in the universe.)
