The chance of meeting them on the other hand is infinitely small.
But if the universe isn't infinitely large, that means there's something beyond it... |
This is a really common misconception, understandably. The universe's size is not necessarily infinite in the mathematical notion of infinity. It very likely doesn't wrap around either. Why it's considered "infinite" is because the universe encompasses all of space, by definition. As quoted from wiki, the Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time everywhere and increases the physical distance between two co-moving points. Plus, from our perspective, the universe seems as though it's only 47 billion light-years in all directions, but only because that is the limit where light has traveled to us. The universe's expansion means this is very inaccurate to the actual size of the universe. Also, the cosmological principle implying that any observer in the universe will have the same observable universe centered around them, is hard for people to grasp, since this also seems as though it would mean an infinite size. In any case, a finite universe does not necessitate something "outside" of it, much like the age of the universe does not necessitate a "before".

It's possible Santa is right and we're not native to this planet. Even if we did arrive in a spaceship 600 million years ago, nothing of that civilization would have made it to this day and age because of corrosion etc. Except human fossils apparently. |
Darwin's theory is only a small piece of evolution. I think if you're questioning whether or not humans have evolved "too fast", you might want to do some more studying on the subject.

Wonderfully, it's recently been projected that the Voyager probes we sent into deepest space - containing nothing but Bach recordings - will run out of power far sooner than expected.
Almost a shame, really.
Imagine the poor intelligences that discovered said probes. This is the last trace they'll ever find of our race.
Long after we're gone. Those notes will live on.
Would almost be enough to think that something of value was lost. If you didn't know any better.
Not that anything is really lost. For in the beginning of music is the myth, and the end as well. |

Actually Drake, I've had quite a few classes on the subject of evolution. I like it a lot, and while I am in no ways an expert, I do know a lot about it.
What I meant with my earlier statement is that not too long ago (couple of months) human fossils have been found which are older than any found before, which seem to indicate that humans have been around a lot longer than we initially thought, which subsequently means that we either "evolved" quite a bit faster than Darwin's theory supports, or we somehow blinked into existence on this planet.
Or time-travel.
Now, there are some small islands in the east (maybe your west) on which rather small humans have survived for quite a long time. Those humans all developed extreme dwarfism in a lot less time than Darwin thought to be possible and went extinct somewhere in the 1800's. This seems to support that Darwin's theory should also encompass rather fast and sudden "forced evolution" through extreme situations, like the scarcity of food on those small islands. You don't just develop extreme dwarfism in 200-300 years according to Darwin. It should take much longer than that.
And this hasn't only happened to humans.
But this has nothing to do with aliens anymore (probably).

Well, think about this: There is only so many patterns that you can form using atoms in a space, so the larger you imagine the universe the more repeating patterns you will come upon, till you reach a point where there is an exact duplicate of you.
Of course, I always partly disagreed with that theory in that most of those patterns would be shapeless. Though there could be life.
There's always the nice theory that advanced aliens made robots to harvest asteroids and have destroyed their system and are now going from system to system harvesting them, and we're next.
Then you got Dyson Spears that could blot out a nearby alien star that we'd have no idea of them being there.
Let's not even get into M Theory and communicating with alternate-membrane aliens using gravity waves.
