unanswerable questions

[clootch]

so you mean to say i just forked out money i could have spent on my girlfriend for weights when i could have used toast

 

[staytrue]

Doesn't work. Shouldn't buy girlfriends anyhow.

 

[loco]

haha

Four options:

1- You create a perpetual motion engine... (i.e. cat and toast spin in mid-air)
2- The cat lands on it's feet, the toast doesn't land buttered side down. The theory that buttered toast always lands buttered side down has evidence against it. We now have a paradigm shift
3- As above, but the inverse
4- The cat and toast separate, they both land the way they are supposed to

The cat lands on it's feet then flip over.

lol

i tried this in my back garden and inadvertently created a small black hole. I have had to move a fence panel to cover it so the neighbours don't suspect their dog was sucked in at the weekend.

lol I love the imagary of this!

Do black holes make noise? Obviously they wouldn't in space, but what about if there was one somewhere else? Say, in your back garden perhaps?

Interesting question. I'm tempted to say "no, nothing can escape a black hole, not light, and certainly not sound." But in my imagination I could imagine it making one quick godawful "SCHLWEPPPppp..." sound for the brief fraction of a second that it took to devour us all.

Why do women take so long to get ready?

Why aren't all rooms room temperature?

 

[January20tha2009]

no idea. you can't improve perfection. (yes my girlfriend is looking over my shoulder)

 

[tracdoor]

That's not a theory.


There's no such thing as a "subatomic molecule"
not only that, but the ONLY place where we notice any kind of change in distance is between galaxies (or galaxy clusters), not between molecules, atoms, or subatomic particles.


The distance between planets is not changing.


No, there aren't.

Interesting question... while true that a black hole in space would now make noise... on earth, I would propose that you would hear it.

Reasoning thus: a black hole is a very small volume, very high mass object. In fact, the mass is so great the gravitational attraction will not even allow light to escape. As such, it would not allow sound to escape either (sound travelling much slower than light).

That said, a sound wave beyond the event horizon would still be able to escape. As air is drawn towards the event horizon, the rapid contraction and movement would cause the molecules to vibrate, thus making a sucking sound (unless the attraction were so fast it would make a loud series of bangs as the molecules broke the sound barrier).

Problem is, the more matter the black hole absorbs, the larger (in mass) it gets. The larger it gets, the larger its gravitational attraction. The larger its gravitation attraction, the more matter it attracts. The more matter it attracts, the larger in mass it gets... (by now you should be getting the idea)

A microscopic black hole would absorb the earth fairly quickly, I would suggest the atmosphere first... with a schwelp sound

Quarks? Leptops?

[brailleonsundays]

Not physics but biology. Most black holes make this sound sooner or later

 

[AlexisInfectious®]

Subatomic *particles* but not *molecules*.


I assume you mean "leptons". See above.

 

[mrsjoejonas24]

Actually, the amount of Hawking radiation is inversely related to black hole size. A microscopic black hole, if such a thing were even possible, would radiate all of its energy away in a fraction of a second, not to mention that even before radiating, it's gravitational pull would be immeasurable at any reasonable distance (even intermolecular distances).

 

[Blacklashes]

What I've posted is proven (Hawking radiation from black holes has been measured). What Spinal has been posting is. . . wrong. . .

 

[sicily]

Having reread your posts on the subject that's more positive for survival in the long term?

 

[UrBestFriendttt]

I guess you could say that.

There was a lot of talk from people when they were building the LHC (Large Hadron Collider, a big particle accelerator) that we could create a black hole that would destroy the earth, or something, until it was pointed out

1) cosmic rays collide with the outer atmosphere with even higher energies, and as far as we know, it doesn't produce black holes, and in fact, there's good reason (having to do with quantum mechanics) to believe that you CAN'T make such small black holes.

2) Black holes that size would evaporate almost immediately due to Hawking radiation.

It's also important to remember that when you make a black hole, the gravitational attraction doesn't suddenly become stronger than before the consituant matter was in a black hole. The only difference is, you can get "closer" to the object. Gravity falls off as 1/r^2 (approximately) and the only difference is that you can get close enough that the gravitational force becomes high.
