Re: To everyone concerned about a manmade black hole

Do you mean worm hole?^^
I've never heard of a whitehole, it might be something else or a typo.
but anyways im gonna look for some vids on blackholes on youtewb.
if anyone would please bare out a long 3 page essay on blackholes that would be nice.
i want to know abot them alot!.
brb searching.
oops offtopic but.
not back on, ive heard scientists were trying to create a wormhole.
you need a super hot ultraviolet light and it has to be very hott, and you shoot an atom or a bunch of them with it.
I can't really remember but scientists ''say'' they have seen or mapped a few.
This was on the science channel ftw.
and to what EnR said, if blackholes don't lead to anything, then where does all the stuff they suck up go?

Re: To everyone concerned about a manmade black hole

if you were to observe a spaceship enter a black hole, first the object would look like it is slowing down, but never reach the "event horizon". The event horizon is spherical area from which nothing can escape without accelerating beyond the speed of light. This is due to space-time sloping downward to infinity. At the center of the event horizon is a singularity (too complicated i dont really get what it is). If you happened to be on the space ship then you would experience time in the normal fashion and at the event horizon you would be ripped into subatomic particles as you fell into the singularity.

EDIT: when something falls into a black hole the mass is still there it doesn't go anywhere. It dissipates through hawking radiation as far as I know, however I am not too sure of how the black hole evaporates exactly.

Re: To everyone concerned about a manmade black hole

Not 100% about this, so correct me if I'm wrong but, black holes don't lead to anything. What they do is eat up anything nearby and then spit it out. Watch youtube videos about blackholes, pretty interesting stuff.

They spit out radioactive energy, actually. In other words, it keeps up with the conservation of mass.

What's stupid is how people are thinking this is going to create a big black hole. We are emitting something like 320-340 trillion protons into the LHC at 99.9 % the speed of light, and the result is going to be a collision that's so small and unnoticeable, nothing will happen. The experiment is being done with cameras that can take 1,000,000 pictures a second for viewing purposes, not purely experimental purposes. Think of the trillions of volts of energy that are running in this experiment. All this energy and ressources, and we're only able to create a pinprick-sized black hole. People need to realize that we really don't have the ability right now to create a big black hole. When you touch things, you're not actually touching them; the electrons on the surface of whatever you're touching is repelling away the electrons on your skin. The same holds true for anything. If we use how many trillions of units of energy at this speed just to collide mere protons, then how would we have enough energy and technology to collide things such as stars to create huge black holes? It just makes no sense and people need to use their head more.

Re: To everyone concerned about a manmade black hole

Sorry if this has been said before, but there are colliding particles on the atmosphere of the earth all the time that are equally, if not stronger, than the collisions that the LHC will be creating. I wouldn't worry about the creation of a black hole really.

Re: To everyone concerned about a manmade black hole

The problem is that black holes of that sort aren't of the variety people are trained to think of. They'll always think of the supermassive, galaxy centered type. They're going to think of the ones deep in space, collapsed stars, that suck in anything and everything.

Contrary to what you may think you know about quantum physics, we have no clue if black holes evaporate or if hawking radiation exists. It's actually part of the reason that we are doing this experiment in the first place. It's all contingents based on contingents based on contingents based on contingents. WHOO! SCIENCE!

Nonetheless, if it creates a small black hole it will probably destroy the whole facility. I'm not saying that this wouldn't be awesome, I'm just saying it won't be harmless.

Re: To everyone concerned about a manmade black hole

When I die I want my bodie shot into space headed torwards a real blackhole (collapsed star) and they people can say i was the first man to go into a black hole.
also where does a blackhole lead? people have said it leads to the other end of the universe or to a totally different one.
quite frankly space intreges me alot. and so do blackholes.

It leads to the ****ing center of the black hole. When matter gets sucked into a black hole, the matter compacts into the black hole.

You're thinking of wormholes. Also: white holes are a ****ing lie get that **** outta here

Same. I'd like to see a satellite get sucked in and see what happens. Of course even light would get sucked in which is why black holes appear black, there is no light. So I'm pretty sure the camera would just show pure darkness. UNLESS IT DOES lead to an alternate universe, dimension, or somewhere else.

hi19: Loved that game.

The camera would be crushed, so even if you could somehow retrieve it (impossible by simple nature of a black hole), all you'd get is a pile of matter with no recorded media. If the media was being recorded using radio signals and the media was being recorded by a device outside of the event horizon, the image would just cut out as the camera went beyond the event horizon.

If you happened to be on the space ship then you would experience time in the normal fashion and at the event horizon you would be ripped into subatomic particles as you fell into the singularity.

How the **** can you "fall" into a black hole? I think a better word would be "****-SMASHED". You even said "ripped apart into subatomic particles". How can you then follow that with a softcore verb like "fall"?

Contrary to what you may think you know about quantum physics, we have no clue if black holes evaporate or if hawking radiation exists. It's actually part of the reason that we are doing this experiment in the first place. It's all contingents based on contingents based on contingents based on contingents. WHOO! SCIENCE!

Yeah, I'm not a quantum physicist or anything. All my knowlege on the matter is pretty limited and has been picked up from shows on educational channels or while skimming wikipedia. Oh and what I've been able to piece together from various science fiction.

But I do know a lot more than the uninformed folks who have a tendency to talk a lot without doing the tiniest bit of research on the matter. I might talk a lot, but at least I've done the tiniest bit of research on the matter.

ps i think it's pretty obvious that hawking radiation exists **** you

oh. i'm sorry. i didn't realize you were more qualified than experts to tell me what is pretty obvious.

you are completely right. we shouldn't, as a society, be spending money to prove things that are pretty obvious already. small margins of error that we feel comfortable ignoring because of their abstract smallness should be ignored because it seems pretty obvious.

Does it mean I'm a more skilled humorist when my joke is taken as serious? Does it mean I'm too sloppy with jokes? Does it mean the reader is predetermined to take me seriously? Am I falling into the trap of an ironic serious response to my joke?

Nevertheless, if I suddenly drop capitalization and punctuation and curse in a more abrasive, offensive, and useless manner, I'm probably joking.

Re: To everyone concerned about a manmade black hole

Well most of the conversation in this thread has a scientific tone, it's not like sarcasm on the internet is easy to detect. Especially when people are posting in a somewhat serious manner.

Re: To everyone concerned about a manmade black hole

There is a 0.0000000001% the black hole will appear.

Of course this statistic is proven because we've already tried this sort of thing before.

Nonetheless, if it creates a small black hole it will probably destroy the whole facility. I'm not saying that this wouldn't be awesome, I'm just saying it won't be harmless.

It would take a while for ~10^32 atoms to collapse into a singularity if you're starting off with a few hadrons or w/e.

You are right about hawking radiation, but there's a problem with this reasoning.

Under the standard model the LHC cannot create mini black holes - the energies associated with it are far too small. The only conditions that satisfy mini black hole creation in theory are those that also require decay via hawking radiation >_>

Thus, as every qualified physicist has agreed, there is no danger here.

I was under the impression that the gamma radiation from the decay of a black hole would probably melt the equipment and the facility because of its intensity.
