Ray is an excellent vocalist :-)

I like the fact that you were all extra-terrestrial this week, talking about UFOS. I completely agree that there is life out there somewhere. There is an equation in cosmology called the Drake's Equation that basically gives the odds that there is intelligent life elsewhere in the universe. I always thought it was interesting (hence majoring in astrophysics) but check it out:

Now, just because there has to be intelligent life out there somewhere doesn't mean that we'll ever meet them. Even if we do achieve space travel that can travel many times the speed of light (which some physicists say is impossible) they may be so far away from us that we’ll never actually be able to see them from Earth. I’ll explain a little below (disregard for non-science nerds):

First I have to explain that the universe is still expanding due to a theory called ‘inflation’. We can tell this because of ‘red-shifting’ in light from distant stars, but that’s a thought for another time. A good analogy to explain inflation is what happens when you bake raisin bread (stay with me here)… Basically you can picture that every galaxy in our universe is a raisin in the bread that is the space that we take up (disregard the fact that we aren’t sure if the bread would then be infinitely large for now). As the bread bakes, each and every raisin gets farther and farther away from each other because the space in between them is actually growing.

Second, we have to consider that even if the universe is bigger than about 14 billion light years, we won’t actually be able to see anything beyond that. This is because even if the light left its source 14 billion years ago, if we were more than 14 billion light years away from the source we wouldn’t be able to see it because the universe is only about 14 billion years old. (Since a light year is defined as the distance light can travel in a year at 670616629.2 miles per second)

So if you put the two together, our window or horizon of what we can see will never be more than how old the universe is… So if the universe is expanding faster than the speed of light (which current data suggests it is) we will actually slowly be able to see less and less galaxies as they leave our ‘horizon’.

All in all, this means that we may never meet an alien, and we may never actually prove they exist… But we can’t rule out their existence.
