What would happen if we made a black hole with the mass of a nickel?

This would be a gigantic explosion—a significant fraction of the rest of the mass of the Earth matter that actually fell into the black hole will be converted into energy. This radiation will be absorbed by the outer layers of the Earth and will vaporize them.

Can a black hole be the size of a ball?

Primordial black holes are predicted to have popped into existence within the first few fractions of a second after the Big Bang. But because black holes are incredibly adept at crushing down matter, a black hole equivalent to roughly five Earth-masses would be only about the size of a baseball.

What happens if u touch a black hole?

Mathur’s fuzzball black holes are actually giant, balled-up collections of strings. So, theoretically, when an object touches the surface of the fuzzball, its mass gets converted into light, generating a holographic copy of its former self.

Would Planet 9 be a black hole?

No such primordial black holes have been detected yet. But they could as easily be primordial black holes floating around the galaxy, the astronomers proposed. If that were the case, the putative Planet Nine could well be a black hole, too, in a distant orbit around the sun.

How heavy is the mass of a black hole?

Others have correctly calculated, that the mass of such black hole would be of the order of 10 17 kg. Heavy, but only a fraction of Earth’s mass, so its gravitational effects would be rather strong close to it, but not globally.

What happens to the matter that falls into a black hole?

This would be a gigantic explosion—a significant fraction of the rest of the mass of the Earth matter that actually fell into the black hole will be converted into energy. For astrophysical black holes, up to 40 percent of the rest mass of the accreted material can be emitted in radiation.

Is it possible to create a penny-sized black hole?

Theoretically yes, but practically it would be impossible to create a penny-sized black hole here on Earth. Forming a penny-sized black hole on Earth would take a huge amount of mass and a method of condensing that mass into a tiny area.

Will the Earth be swallowed up by a black hole?

A black hole with a Schwarzschild radius of about a centimeter, which would make it about the size of a coin, would have about the same mass as the Earth. The reason the Earth will be destroyed but not simply swallowed up is because the Earth will be resisting the black hole in at least two ways.
