jamey2k9 Posted February 8, 2009 Share Posted February 8, 2009 blackholes can absorb anything light matter ( possibly even time) what would have the power to do that i mean it's more than just a gravity well so what is it Link to comment Share on other sites More sharing options...
iNow Posted February 8, 2009 Share Posted February 8, 2009 That's an incredibly broad question, and there is a lot to cover. Start here, read, ask specific questions when you have them. http://en.wikipedia.org/wiki/Blackhole Link to comment Share on other sites More sharing options...
Klaynos Posted February 8, 2009 Share Posted February 8, 2009 It is an object with all it's mass within the Schwarzschild radius, the most interesting fact known about them (the event horizon) is a purely gravitational effect. Link to comment Share on other sites More sharing options...

gre Posted February 8, 2009 Share Posted February 8, 2009 What time is it inside a black hole? .. If time changes does to gravitational effects, could the time be either 0 or infinite? Link to comment Share on other sites More sharing options...
Mr Skeptic Posted February 8, 2009 Share Posted February 8, 2009 What time is it inside a black hole? .. If time changes does to gravitational effects, could the time be either 0 or infinite? Inside the black hole is stuff that we will never observe (if what we know about black holes is correct), so it is really hard to tell if our guesses about what might be inside are in fact correct.

NowThatWeKnow Posted February 9, 2009 Share Posted February 9, 2009 What time is it inside a black hole? .. If time changes does to gravitational effects, could the time be either 0 or infinite? A black hole could have the mass of the Earth or millions of stars. A black hole with the mass of Earth would have a similar gravity as Earth. And I would think a similar time dilation. I have a feeling that stopping time is like reaching the speed of light. You will never quite get there. Link to comment Share on other sites More sharing options...
Daecon Posted February 9, 2009 Share Posted February 9, 2009 A black hole could have the mass of the Earth or millions of stars. A black hole with the mass of Earth would have a similar gravity as Earth. But only if we were the same distance away from the black hole as we are from the center of the Earth now, right?

NowThatWeKnow Posted February 9, 2009 Share Posted February 9, 2009 (edited) But only if we were the same distance away from the black hole as we are from the center of the Earth now, right? Someone please correct me if I am wrong but I would guess that gravity 4000 miles from the black hole would be similar to gravity at the earths surface. A new set of rules apply as you get closer to the black hole. Going towards the center of the earth your weight would decrease and getting closer to the black hole your weight woud increase. All bets off when you get close to the black hole. Again, corrections welcome if needed. Edit - I love it when I am right. finally http://amazing-space.stsci.edu/resources/explorations/blackholes/teacher/sciencebackground.html#5 Edited February 9, 2009 by NowThatWeKnow Link to comment Share on other sites More sharing options...

Airbrush Posted February 10, 2009 Share Posted February 10, 2009 My favorite bit of trivia about black holes is that a black hole with the mass of the Earth would resemble a flat black marble the size of a walnut. Link to comment Share on other sites More sharing options...
