probably neither, since the gravity would crush you before you could feel it. and your head would explode if you didn't have a space suit on... but most people would just say " I don't know, I've never been in one."
Current theory indicates that black holes do have a small finite entropy and temperature consequential to principles of thermodynamics, attributed to quantum effects. Named after the astrophysicist that proposed it, this Hawking radiation can cause the mass of the black hole to slowly decrease and eventually the black hole may evaporate entirely. Because the radiation is very weak, black holes could generally be characterized as 'extremely cold,' mitigated only by this radiation. Also, the bigger the black hole the weaker this radiation is calculated to be, such that the largest black holes would be colder than even the very low cosmic background temperature.
Black holes themselves do not give off heat. However, if a large amount of matter falls into a black hole at once it will become extremely hot at emit very large amount of heat before passing the point of no return: the event horizon.
You can assign black holes a temperature according to their Hawking radiation. This makes them EXTREMELY COLD - a typical black hole would have a temperature less than a microkelvin. From Wikipedia: "... temperature inversely proportional to the mass of the black hole. ... A black hole of one solar mass has a temperature of only 60 nanokelvin."
Based on its Hawking radiation, a black hole is extremely cold for most of its lifetime. Somewhat less than a microkelvin, depending on its mass.
Black holes do not die but they can evaporate.
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Yes. They get sucked into black holes all the time!
The most massive stars will die as black holes.

Black holes do not emit light, so black holes can not be seen this way. But black holes emit X-rays, but stars are not hot enough to emit X-rays. When black holes suck up stars, energy goes to the black hole, and come out as X-rays.
No. The apparent dark areas on the sun are not black holes; they are sunspots. Sunspots are areas of the sun's surface that are not as hot as their surroundings.
No, black is not a hot color because it is dark and gloomy like a cold color. Hot colors should be bright like yellow. :)
Most black hole are found from the X-rays emitted by extremely hot material just before it disappears.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Cold.
hot, cold yes, no black,white
It is known what will happen. You will get sucked up! But before you get sucked up, Black Holes give flicker of black hot gas. Black Holes have so much power that they can't control it. So that's why they suck up everything in their path. Fun Fact: Black Holes are actually stars that died and contain so much power!!
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.

my guess is that a black hole would be niether because there is no atmoshere in space, although, it could be cold. i KNOW its not hot. Zachary mcalpin (13)
