hehe, right. I can't imagine how it would look.. maybe just like a ball of light?

Someone clarify, please.
Even black holes have polarity, points from where massive amounts of gamma rays and heat are emitted caused by matter getting accelerated to near-light speed as it falls in. The emissions aren't coming out from the black hole itself, they're from the matter falling in before it crosses the event horizon (point of no return).

Note the gamma burst jets in this.:

Imagine what kind of space craft it would take to travel through a black hole?

Yes and were talking about gravitational forces so strong, that if you threw an object into the black hole one end of the object would be experiencing a thousand, even a million times greater gravitational force than the other end. Basically ripping matter apart to it's basic components.

If a planet was to be eaten by such a black hole right now, would we be able to see it in the near future, or is it simply too far away? I wonder.

It depends on how many light years the black hole is located. It will take as long as this distance (in light years).

Closest is at 8000 light years away. That's why things we see up there right now are past events.

One thing that always bothered me about black holes is the jets going in both directions as shown in nearly all artists impressions. Wouldn't this mean it sucks matter in from both sides? So, where does the "hole" go? the more you think about this stuff and all the ideas that flow through your head boggle the mind >_>

I don't think it would be a great idea for us to ever be able to see a "black hole". If we can see it, that probably means it can see us. eek.gif
