what will happen if there is a black hole near the earth?

Answer 1

That depends where it is going, and how big it is. If, for instance, Jupiter was replaced by a black hole of the same mass, and having the exact same orbital characteristics, it would follow Jupiter's orbit, and we would not feel anything at all here -- except for the weird scenery offered by the gravitational lensing of the black hole, and the occasional gamma ray flash released by objects falling in the event's horizon.
If a massive black hole was to get near the Earth, first we would notice it because its gravity would perturb the solar system a great deal. Add another object with a mass similar to the sun in a system where everything had billion of years to reach some equilibrium, and planets would fly off in all direction from the gravity effect, even while the black hole would still be as far from the Earth as Neptune.
If it was to get close enough to the Earth, the tidal force would tear Earth apart (remember that Earth stays together only by the force of its own gravity. Bring in something that has more gravitational power in the vicinity, and rocks will fly off, or more accurately fall down off to the black hole, since the black hole will define the new "down".
But again, that would require that black hole to have a large enough mass.
Now, there is another thing to consider. Even a smallish black hole, one with the mass of the moon say, getting close to earth, say same distance as the moon, would be gobbling up the occasional rock. This in turn, would release intense gamma radiations that would kill anyone on the planet.

Answer 2

A black hole is no different than any other massive object. The Earth and the black hole would be gravitationally attracted to each other, but this would no more mean that the Earth would get swallowed up by it than say the Earth would pull the Moon down.

For whatever reason, people think the Laws of Motion are somehow suspended when a black hole is involved.

Answer 3

Can't happen.

Under the theory the moment a black hole's event horizon (gravity well) comes in contact with the Sun the Sun and the whole solar system will get pulled towards it and the closer its the more elegonated it will be and the faster it will move.

Life as we know it would end long before the Sun got sucked in.

IT is estimated that the process can take as long as hundreds of centuries

Think of a black hole as a drain in an olympic size swimming pool and the sun a little rubber ball floating on top.

The serious implications would hit until more than half the pool was drained.

Answer 4

If it was close enough to draw the Earth into its gravitational pull, it would suck the atmosphere off the Earth first, which would kill everything on the planet. So, you wouldn't be alive as the earth disintegrated piece by piece in a long stream of debris being pulled toward the center of the black hole. Also, it would do the same thing to the Sun and other planets. Everything that came within its grasp, including light can't escape.

Answer 5

This is a way cool question to ask. If there is a black whole near earth, It is only obvious as to what will happen. However, in order to understand that you have to first know what a black whole is and is capable of doing.
Black wholes are like people who can never get enough of eating. no matter how much they consume they still are hungry fro more. so it is only presumed that if there was a black whole near earth, all of earth and surrounding planets will be drawn into it.
does this meant that life would cease to exist? that I can't really say since i never lived through a black whole. However, scientist do believe that black wholes are other dimensions that exist beyond the knowledge of man.

Answer 6

It really depends on how close it was and how big, a black hole with the mass of the several suns outside the solar system could perturb comets or effect planetary orbits. Closer in the black hole would distort orbits, and throw the sun out of position, it might shred the sun into disk of material and swallow it in a storm of radiation.

However a small black hole (primordial black hole) with a mass like that of the Earth could pass through the solar system and be unnoticed.

Answer 7

If there would be a black hole near the earth then, you couldn't have asked this question. jokes apart, the black hole will suck all the material on earth or at least it will tear it apart and all the material will start circulating around black hole.
even the sun and our whole planet system will undergo the same fate.

Answer 8

If a black hollow develops close to earth, what it is going to do is it is going to deliver each thing, and that i advise like planets, the solar, different photo voltaic structures, asteroids, meteors, each thing that has gentle and it will be beaten. No you gained't see each thing being sucked right into a vaccum because it's going to be truly quick (some seconds for each thing to bypass away). the in trouble-free words way a black hollow could improve close to earth, is that if the solar ran out of capacity, that isn't take position for yet another, what, 10 billion years? when you consider that there are not any stars that on the aspect persons, or to destruction, it isn't achieveable. No, you does no longer see some thing. regardless of if that did take position, you'd be lengthy useless.

Answer 9

A black hole is the last stage in a life cycle of a star.There will not be any light radiations, it is a region of very high gravity.therefore it would have swollen the earth and even the solar system.

Answer 10

Depends on how close. An object could orbit a black hole and remain in orbit without being pulled into it if it's at a far enough distance.
If close enough, the earth would get pulled towards it and turned to vapor.
