Professor Edmund Whitmore takes the stage to make an argument most scientists won't say out loud: that we are probably alone in the universe. Not "we haven't found anyone yet." Actually alone. The only technological civilization that exists, or has ever existed, within any distance that matters.

I find that hard to believe. Just because our technology has not yet found others doesn't mean that we're alone. There's just too many millions, billions, trillions of possibilities for me to believe we're alone.

Also, "within any distance that matters". That's not very far in terms of the universe.

I know the distance to the nearest star, other than the sun, is about 4.5 light years away. How far to the next nearest star?

As far as right now goes, the most likely scenario is that we are totally alone......as of right now.
