Pluto shouldn't be a planet, and isn't now for a good reason. It's part of an asteroid belt, and there are actually chunks of rock out there that are bigger than it is. It has no proper orbit and very few characteristics that place it in the same category as the other planets. I believe it is actually the cause of a new subcategory of planets now that so far includes two or three other asteriod objects of similar size.
Black holes are very cool, but super scary in a way. They tear things apart to an extreme, nothing can exist in them, even light is taken apart.
As to life on other planets; I think there is a definite possiblity that there was once life on Mars, and there is no way that there is no life except humans in a place as big as the universe. Considering the fact that most of us can barely imagine the immense size of the solar system, let alone the universe, makes it nearly impossible to think we are the only "living" planet in it.
There are so many stars out there in the sky we see at night. There are known to be planets circling at least half of them, probably more. For me, I think it would feel very lonely here, if I were to think that Earth is a unique circumstance; that nowhere in the universe other than here, life managed to evolve.
Something else that is super cool about the universe is the nebulas and other star patterns that can be observed. They are so beautiful. And fantastic. I can't wait to be able to study them in more detail.

For Pluto: I'm mnot going to take a side in thius arguement, as I have no unbiased opinion. However, I do want to make a clarification. Pluto and its moon, Charon, are not in an asteroid belt. The Kuniper Belt, which it is located in, contains asteriods, comets, planetoids, and other heavenly bodies.
For black holes: I once read about how scientists think that as all matter enters a black hole, it is streched super long and super thin in a spaghetti effect.
One more question to ponder: Do feel the universe will one day end in the Big Freeze (where all galaxies expand forever until they become too cold to exist), the Big Crunch (where the galaxies expand until so far, then are brought back together and collide), or something else entirely?
