I have heard that miniature black holes traveling through space might come in contact with the Earth.

Question

If this happened what would result?

Answer 1

Well, black holes is a region in space with a STRONG GRAVITATIONAL PULL THAT NO MATTER AND ENERGY CAN ESCAPE, EVEN LIGHT.

If black holes will come in contact in the Earth no one possibly what will happen to Earth. I think that there is a strong possibility that our life would be more in danger.

Answer 2

a minature black hole wouldn't do anything to us

however, there are roaming black holes, right in our own back yard of the galaxy, and some of them are of a pretty d**n substantial size...

enough of a size to actually pose a risk to us...

the first noticeable effect would be atmosphere being sucked off into space towards the black hole.... if you were still alive after this (very little would live if the entire atmosphere disappeared long enough to see the second stage)

then, essientially, earth's gravity would would be neutralized by the pulling gravity of the black hole. you, animals, plants, pretty much everything would become increasingly distorted (since most things on earth exist in the shape and form they do because of the force of gravity, the only things that wouldn't warp would be rigid objects/features, but eventually even those would be effected too)

this effect would just continue to increase, and first everything not nailed down would be sucked off into space, then would follow tall objects, like skyscrapers would be ripped off their foundation, but would likely just crash to the earth

eventually, even the shape of the earth alone would begin to distort and turn more into an oval

edit:

no i didn't get it from there... i've heard it used in number of documentaries (i've probably watched 400 or more in the past year) and it's the best way of describing distances that are close when compared to the size of the entire galaxy... because if you actually say how far away they are (in miles) it sounds REALLY far.... and in this case, it being 'really far away' it would seem as they pose no threat to us whatsoever... these distances aren't as far as they seem becuase how fast everything moves.... much much faster then anything moves here on earth... (that we see anyways) so it just adds to the effect of thinking those things are at an unfathomable distance, when in actuallity, they're not.

Answer 3

where did you hear that? If any black hole came near Earth we wouldnt be able to talk about it

If a black hole were anywhere NEAR the sun or Earth we would die and not to mention if one were near a planet gravity would mess up and fling stuff everywhere.

AND THERES NO SUCK THING AS A SMALL BLACK HOLE CUZ AS IT GOES IT BECOMES MORE MASSIVE

Answer 4

There might not be any cookies left.

Answer 5

Nothing would happen. They have very small masses, and wouldn't do anything. Black holes don't automatically suck things in. If a black hole were to replace the sun, but had the same mass as the sun, we would just orbit like any other day. Now, no sunlight would mean all of life would die, but we wouldn't be sucked in. Only supermassive stars collapsing, thus forming supermassive black holes suck things like stars and planets in. There are some black holes that are the size of a tennis ball, and because they have such a low mass, we wouldn't be sucked in at all. The gravity has to be great enough, and with a tennis ball sized black hole, nothing would happen because it isn't massive enough to have anything close to a significant gravitational pull.

EDIT: Maybe BANG should take 10th grade ASTRONOMY.

EDIT 2: BANG, you saying that small black holes grow just proved my statement above. Thanks! And next time, take some astronomy courses.

EDIT 3: Yes, as another person said, there are roaming black holes in our "cosmic backyard" (love the wording, did you get that from NOVA's episode on black holes?) that are pretty large, and could affect the Earth.

Look, the common misconception about black holes is that no matter how big or how small they will suck everything that comes in their path. That is not true. Their gravitational pull is based on their mass, just like Earth's and everything else in the universe... even you and me. Minature black holes simply aren't massive enough to suck in stars or planets.

Supermassive black holes are the ones that light can't escape. Those are created when huge, supermassive stars, collapse under their own gravity leaving something called a neutron star, which is only 10 miles in diameter, but is so dense that a teaspoon of its matter would weigh over 100 tons. Thats how dense it is. All of this matter is pulling towards the core under extream pressure and gravitational force. Eventually the gravity is so great, that it collapses under its own weight, leaving this HUGE rip in spac time. These black holes are so powerful that they approach an infinite amount of force. Equations no longer work when it comes to these black holes. These things are so mysterious that Albert Einstein said they were freaks of nature and that "nature simply wouldn't allow them."

Supermassive black holes are a fairly common thing. There is believed to be one in the center of all spiral galaxies, and most other galaxies. And our galaxy is no exception.

So how would we know we were being pummled by a big black hole? First off, our moon wouldn't probably start acting strange, followed by the atmosphere being sucked in, and from there its a bit of a mystery. Potentially, the enitre Earth could be swallowed. But this black hole would have to have a mass much greater than that of the sun.
