Think of it as the beer bubbles expanding in the tummy. The further it expands the more ones head ache. :lol:

If the universe keeps on expanding. Detecting life ouuut ther will also be more remote.
In the end, the earth will be alone! Even if we detected life in, for example, Alpha Centari, by X years from now AC won't be around anymore cause it's furhter away now than X years ago? That's sad... :-(
