Why doesn't dark matter fall into a black hole?

Question

Our galaxy could not be "sucked in" to the Black Hole at it's center because of the great distance between it and the nearest matter. If 95% of the universe is composed of "Dark Matter" and ergo also our Milky Way, then why isn't it feeding the Black Hole thereby increasing the event horizon to "someday" include all of the galaxy?

Answer 1

I think no MATTER is present in dark matter and how can a black hole absorb dark matter? And 95% of universe is empty (composed of dark matter). If the final black hole increases up to event horizon, then all the matter will be sucked in by black hole...

Answer 2

We don't know enough about dark matter to predict all of its characteristics. If it responds to gravity the way ordinary matter does, it will fall into a black hole in the same way. The closer it is, the faster it will move, the farther, the slower, out to a diameter where the black hole's gravity is effectively zero. Because a black hole is already so massive, any matter added will add almost nothing proportionally to its mass, so it won't "grow" appreciably and the size of its gravity well will expand only very slowly. So once the nearby area is cleared, things will be pretty stable.

Of course, if dark matter behaves differently under the influence of gravity, we can't predict what will happen. The opposite of falling in is going away. Maybe dark matter is repelled by gravity. In either case, the galaxy seems safe for quite some time.

Answer 3

My understanding of the phenomenon is that nothing escapes the gravitational pull of a black hole...not even light. And, inevitably, everything succumbs within it's gravitational range. Though I am no astronomer, I try and pay attention when the discovery channel is on : )

Answer 4

To a particular volume, darkish count number is amazingly very like the count number in the singularity of a black hollow, they have gravity yet are unaffected through the different forces inclusive of electromagnetism. certainly black holes are between the applicants for darkish count number, a black hollow is termed a MACHO ( huge Compact Halo merchandise ) in the quest for darkish count number.

Answer 5

Black holes and dark matter would never be able to find each other.

Answer 6

Ah, but they are falling into a final black hole !
Only, it gets time to get there ! a dozen billion years it takes ...

Answer 7

dark image wil wil fall in dark , but u cant see one color on the same color ,

easy way to test this,

take some color paper, if u write something on the paper with same color sketch , u cant find there anything
