Ever wonder why alien races from other planets have not fully revealed themselves to us yet?
OK, I'll take the bait.
Maybe it's because there are no alien races out there. Or maybe because the alien life forms that have been able to develop in remote worlds are not intelligent. Or maybe the one or two other intelligent life forms that exist (assuming they do) can't figure out a way to bridge the gap of quadrillions and quintillions (literally) of miles out there.
There probably are on the order of 10
12 galaxies. If they each, like ours, have 10
11 stars that would mean there are on the order of 10
23 stars in our universe. If each of them has 10 or so planets, we can expect our universe to hold 10
24 planets.
But what is the chance that intelligent life would evolve on one of those? We don't know, having just a single case (ours) to study. Is it 1 in 10
20? Then there would be thousands of intelligent species out there. Is it 1 in 10
28? Then thousands of universes like ours would have to exist before even one intelligent species evolves.
What is the probability? 10
20? 10
28? Much higher? Much lower? We simply don't know, and anyone who does claim to know is just guessing.
Not sure how this fits in "transgender talk" but it's an interesting enough question to be worth answering.
