@micronesia: You probably already know this, but while SR adds extra challenges, it opens up another possibility too. Because of the time dilation, a trip which would be very long for observers on earth would only take a short time for the astronauts. So, in theory an astronaut could travel one million light years in only one year of "travel time".
So what you're saying is... I can be IMMORTAL?

Yes I neglected to talk about that (and implied that it would require some more understanding, which I believe it does). However, I think it's difficult to reach speeds capable of smooshing together the space in front of you.

So let's say there is a star twenty light years away and I traveled there in a split second I would have "traveled" twenty years back in time, no?
If the bigger black whole consumes a smaller black hole is there any understanding of what happens, with the smaller black holes energy. Is like a drain swallowing a drain?

I just made up the bigger black hole eating the smaller black hole because it seems to make sense. It might not even be true. Some people posted that they combine, so the small black hole's energy would presumably add to the bigger black hole's energy.
Has anyone actually observed two black holes interacting, or has it just been simulated?
God damn, this thread makes me feel so stupid. And when I say me, I am referring to humanity because we don't know so many answers. Also, I feel so damn small in the big picture. It makes me feel like I can do anything because I am so small in the big picture of things that it wouldn't even matter. Like all the people making girl threads should come here, realize how small they are in the big picture, beef up their confidence that it won't even matter if they get rejected, and then go do stuff in the real world instead of worrying and making blogs about it.

I believe they've only just simulated a combination. I'd assume it's pretty hard to find a black hole let alone verify that it is one and hardest of all... to watch two collide.
The problem with a black hole is that everything associated with it is completely theoretical. We couldn't possibly know what happens behind the Schwarzschild radius with the tools we have today and possibly for quite a while. As to humanity's ignorance of natural laws, I can only point out that we have come a long way from beating each other over the heads with bones.
Also is the Bekenstein bound stating that a back hole can become too saturated? One of my favorite thought experiments involved a suitcase full of entropy being tossed into a black hole and its violation of a critical law.
To the one reading "The Black Hole War" get ready for the mindscrew of the complementarity and holographic principle in relation to a black hole.

near lightspeed travel is really made a bitch by relativity
time dilation would actually be a plus, aging slowly relative to the rest of the universe wehen going fast would be helpful towards not dying of age during the trip
mass increase would make the amount of energy needed to get up to that speed insanely high, the speed itself combined with ambient hydrogen and helium would make the entire ship a radioactive hazard, and perceived acceleration differences (that go with a factor of gamma cubed) would make getting up to the target speed a bitch, even if you had the aforementioned insanely high amounts of energy

oh on the subject of black holes, its considered that quantum entanglement could be used to probe the insides of them, because entangled particles violate the information at speed of light limit, meaning its no problem that light cant get out (in fact, entanglement of virtual particles from the quantum foam is how hawking radiation supposedly takes place too)

Time dilation is what causes the mass increase and crap... so it's a double edged sword.
