Can dark matter be black holes?

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.

Can black holes absorb dark matter and does it add to its mass?

Once you have a black hole, everything that crosses over to the interior of the event horizon from the outside — including dark matter — will add to its mass. But to form a black hole initially, you need normal matter to do it.

What happens to matter sucked by a black hole?

When matter is sucked in, it must be destroyed because black holes are only a point but the Conservation of Mass theory says that matter can’t be destroyed, it must be converted into another form of matter.

Is universe inside black hole?

The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.

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.
