What if a black-sized black hole attacked the Earth?

In the vast universe, the black hole is probably the most feared 'evil spirit' we have ever known. With enormous gravity, no matter, not even light, can escape the black hole if they cross the boundary of a safe distance.

The true power of black holes

We can completely create a black hole.

In theory, it is possible to create a black hole by itself, by compressing a mass of matter large enough into a space small enough to distort spacetime. Suppose, if you wanted to turn Mount Everest into a black hole, you would have to compress this entire mountain to the size of just a few atoms. Although the black hole formed in this case may sound small, one thing is for sure, you will never want to stand too close to it.

To make Mount Everest a black hole, we have to compress this mountain to the size of just a few atoms.

It is estimated that the 10-meter radius around this atomic-sized black hole will have a gravitational attraction equal to that of the Earth's surface. By now you probably have some idea of ​​the power of this cosmic god.

The 10-meter radius around this atomic-sized black hole will have the same gravitational attraction as the surface of the Earth.

Turning to a more imaginable size, what kind of disaster could a black hole of a coin be if it were close to our planet?

The question posed above actually has two answers, depending on how we determine the size: mass or diameter?

Hypothesis I: If a black hole has a diameter equivalent to a coin

The black hole is about the same diameter as a coin, and its mass will be approximately that of the Earth.

As mentioned, atomic black holes require the same amount of material as Mount Everest. Therefore, in the case of a black hole with a diameter equivalent to a coin, its mass will be approximately the same as the Earth. In terms of power, the gravity of this 'coin' black hole will be 1 billion billion times more than our Earth.

If this black hole were too close to the Earth (beyond the Roche limit: The closest distance the two celestial bodies were) , the end would be really tragic!

The Earth will be affected by the huge gravity of the black hole and begin to orbit it.

First of all, it must be confirmed that the blue planet is not simply swallowed by a black hole and disappears in a snap! What actually happens is that the Earth will be affected by the huge gravity of the black hole and start orbiting it, instead of the sun. At the same time, each part of the planet will be separated and sucked into the black hole. This cosmic god's meal will be slowed down a bit because of the rotation of the Earth's axis. Even so, the end of extinction will also come. In the end, the remaining matter of what used to be Earth will be turned into molten lava and form a disk around the black hole.

Surprisingly, the Moon will be virtually unaffected, if only the orbits will be more elliptical than before.

Hypothesis II: If a black hole has the same mass as a coin

Compressing the 5g of material we have would be very small.

A coin usually has a weight of about 5 grams. Therefore, to compress 5 grams of matter into a black hole, the god we have will be very small. So small is the size difference between this black hole and an atom the same as the difference between an atom and the Sun. However, you must not underestimate its power!

The black hole will constantly evaporate the available matter or suck it back into the universe.

It should be known that the black hole will constantly evaporate the available material or be drawn back into the universe, called the 'Black hole evaporation' . It is this evaporation that will reduce the mass and energy of the Black Hole. Therefore, no matter how many planets are swallowed, the black hole cannot increase its mass. Over time, black holes will shrink and disappear. It is worth mentioning here that the evaporation in the small black hole is much stronger than the big black hole.

Going back to the penny-sized black hole, the evaporation is so small that the evaporation takes place so quickly that it creates an explosion, which is estimated to be equivalent to 100,000 tons of TNT. The power of this explosion, of course, doesn't break the Earth, but it is enough to wipe everything out of its sphere of influence!

The power of a black hole with a coin is enough to wipe out everything within its sphere of influence!
