The best place to look into for black holes is contained by a region of space that?

a) has recently lost some stars.
b) is ominous and empty.
c) is cooler than its surroundings.
d) has strong X-ray seepage.
Answers:
d - contrary to most people's belief, black holes radiate; they are dissipating at the same time as they are growing.
b.
Definitely d. Black holes absorb activeness and radiation but they also vent radiation through jets coming through their poles. Black holes don't give rotten x-rays but the matter orbiting it does.
A make sense, of course, you find neutrino stars instead.

b also logically but would take years or longer to find one, considering we look at the pallid around black holes to see if they curve into one spot, but if the region is dark and empty, later not much chance of this either.

c is a bit of a myth...

d is probably the best style to find black holes, as they do radiate.

Of course, you could just look at the centre of our galaxy, or any other galaxy contained by theory....
d) has strong X-ray emission.

Contrary to the other answerers, I hold that black holes themselves do not radiate. What radiate is the heated, infalling mass stolen from a companion star. Contrary to popular believe, a large part of this mass does not tip out into the whole, but orbits the hole contained by a accretion disk. What we can observe, is the disk.
d) If a region of space have strong X-ray emission, there's a chance that it's coming from the bits and pieces being pulled into a black hole. Source(s): http://en.wikipedia.org/wiki/Black_hole#…
