How do black holes interact with dark matter?

But in order for dark matter to collapse enough to form black holes, it must interact with itself. That way, it can lose all the kinetic energy gained as it collapses, allowing it to reach high enough densities to trigger the formation of a black hole.

Are black holes responsible for dark matter?

Dark matter, the mysterious substance that exerts gravitational pull but emits no light, might really consist of vast concentrations of ancient black holes created at the very start of the universe, according to a new study. …

How do black holes affect matter?

Dark matter does not reflect light or interact with ordinarymatter except through gravity. So when dark matter is swallowed by a black hole,it behaves somewhat differently than normal matter, the new study found. For example, as normal matter falls toward a blackhole, it heats up and radiates light.

Could black holes be made of dark matter?

In theory, much smaller black holes could have formed in the early universe. These so-called primordial black holes would be far more difficult to detect, and they could potentially exist in large enough numbers to make up all dark matter.

What effect does a black hole have on matter?

If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself.

What do you think happens to matter in a black hole?

First of all when matter falls into a black hole it has to pass the vent horizon. This is the point where not even light can escape. If the hole is not really large, anything approaching the event horizon will get torn apart by gravitational tidal effects.

Does a black hole have matter in it?

A black hole is no more made of matter than is the gravitational field of the Earth. A black hole is a region of spacetime. It’s mass does not come from matter but from the curvature of spacetime itself.
