Is there ever a chance that a blackhole could come by Earth?

Question

If so, when or how?

How are they formed for that matter as well?

Answer 1

no there is no chance. the closest black hole seen that could actually suck the earth in is the supermassive black hole in the center of our galaxy. the sun isn't close to being massive enough to collapse under its own gravity into a black hole. i don't think the earth will be swallowed up by a black hole anytime soon.

as for how they form:

the leading theory sugests that black holes form as a result of collapsation of a red supergiant. when a red supergiant dies, it sometimes will become a neutron star which is so massive, it has close to an infinite gravitational pull. the neutron star is very small... it is only about 10 miles in diameter. but it is so massive, and dense that it has a very large gravitational pull... close to infinity. this neutron star's gravity will eventually cause it to collapse under its own weight. because it was so dense, it creates a rip in space time, which inturn is a black hole. thats the idea in a nutshell.

Answer 2

well dude i got news for you, the other day i was watching the science channel and they said that theres a black hole in the center of our galaxy, also that were getting closer to collide with andromeda which occur in a few billion years now andromeda has a massive black hole inside and so do we so if in that collision we happen to get drawn inside the galaxies black holes we could end up in one, chances are slim but the chances are there

Answer 3

No

Answer 4

have I got a story for YOU!

Answer 5

Slim, extremely remote.

The fact is that black holes that are formed by the collapse of a star having gone supernova have to be more massive than the sun is, so way before it would get close enough to the earth, it would measurably affect the whole solar system (remember that the sun's influence, by definition, extends past Pluto already). For the record, small red dwarf star, much smaller than the sun, outnumber star like the sun  3 to 1, while stars capable of turning into a black hole are outnumbered by sun like stars by at least an equal margin. So, in effect, you'd have much more chance of a red dwarf passing trough our solar system and disrupting it that of a black hole ever doing the same.

And of course, this would have to imply that stars (and black holes alike) are roaming about the galaxy, usually they pretty much remain where they are, the stars essentially move in the same general direction, with rather low relative proper motion.

Answer 6

i dont think so

Answer 7

Not in our lifetime.  There is a black hole in the center of Milky Way galaxy, but we are on the outside edge of the galaxy and we're too far away from it for it to suck us in.

Black holes are formed when an object's internal pressure is insufficient to resist the object's own gravity. For stars this usually occurs either because a star has too little "fuel" left to maintain its temperature, or because a star which would have been stable receives a lot of extra matter in a way which does not raise its core temperature. In either case the star's temperature is no longer high enough to prevent it from collapsing under its own weight.

Answer 8

Not really.  Our Sun isn't massive enough to become a black hole, and the only natural black holes are formed when a massive star dies (or two collide).  That happens about once a century in our galaxy.  Not very common.  Not to mention the fact that the black hole that forms from that would just continue on the star's path around the galaxy - it's not like it suddenly veers off to go hunting for planets.  We really don't have anything to worry about.

Yes, CERN and the LHC might create mini black holes.  But we've done that before - at Brookhaven National Labs less than an hour from NYC.  They evaporate instantly, and were only made out of a few atoms to begin with.  They pose no danger to the Earth at all.

Answer 9

yes there is

Answer 10

A fact that was recently discovered is that there are over 30 known "Supermassive Black Holes", and they are much more common than previously percieved. Scientists suggest there is one at the centre of pretty much every galaxy.
