what would happen if I stuck my finger in a tiny black hole!?p.a ...don't be dirrrty!?

Question

welll I was talking to my sis about something amazing that Swiss science people are doing somthing with atoms trying to spilt them and there is a small chance that they could make small black holes and I thought cool! I wonder what would happen if I stuck my finger in one ? Got any ideas I'd love ta know! How cool tho!x!

I probably have this wrong so if you know about this please correct me. Also they say there is a small chance that there could be a black hole that would engulf the world!.what about this!.

Answer 1

black holes radiate away energy over a long period of time.

theres 3 things wrong with what most people think when they hear about the mini black holes.

1) a normal black hole has no more gravity outside of the event horizon than the star that went into making it, so these mini black holes would have no more gravity than an atom.

2) it would be small. the size of a few atoms at most.

3) it would disappear in probably a billionth of a second. we've all be told that black holes dont let anything out of them. well now we know thats not true. all black holes radiate away a stream of particles constantly, but very slowly and in small numbers. with a mini black hole all of its mass would radiate away in the tiniest fraction of a second.

so i guess if your finger is the size of an atom and u are amazingly fast with your hands then it could effect u in someway...

Answer 2

Actually, no, they wouldn't be of the Planck Mass. Just to, "humor" you, how could they?
How can subatomic particles gain so much mass that they would weight about 1/4000th of the weight of the flea?

What would happen if you stuck your finger into a tiny black hole would be that you finger be sucked in, slowly but surely. The gravitational energy would be too small to do anything, but maybe a few atoms would fall in.

To give you an idea:
The Planck Mass is the minimum mass for a black hole to have a radius equal to its Compton wavelength, and would have a lifetime equivalent to the Planck Time (which is 10^-43seconds).

The black holes produced in the LHC would be unstable, but they would exist for a finite (although a non-recordable amount) amount of time. Why? Because a particle that has a non-zero mass, the faster it goes, the mass increases. Its the same principle that dictates that one cannot go at or faster than the speed of light. Because a photon is massless, it can. A neutrino, which travels at almost the speed of light, has a non-zero mass.

So yeah, its not going to happen.
The smallest stable black hole that would have a lifetime of about the age of the universe, you would have to compact Mount Everest, into a really, really, really small space. To put it in proportion: If Earth was to turn into a black hole, it would be about the size of a marble.

Answer 3

Not much on the size scale that they are making them...

The black holes that CERN and FermiLab are attempting to create would not last long enough for you to get your finger to the event horizon and get it sucked in.

(They are expecting the duration of existence of these black holes to be on the order of 10^-30 seconds to 10^-43 seconds (the Plank time).)

Answer 4

The black holes you're thinking of would be infathomably small and exist for an infathomably short amount of time (and believe me, "infathomably" is a very conservative description.)

But just to humor you, a microscopic black hole is predicted to be about
.000000000000000000
000000000000000016
meters wide, have a mass of about .000002 grams, and would last for about
.000000000000000000000000
000000000000000000000000
000000000000000000000000
0000000000000000000000000001 seconds.

Answer 5

Maybe not as "cool" as you think. Your finger and the rest of your body would be sucked in and squished down to a size to fit in the black hole.

Answer 6

ur body would be squished into the black hole and it would most likely hurt

Answer 7

Your finger would get stretched into infinity..as it pasted "event horizon" ....
