What would happen if you were teleported to pluto/sedna for 1 to 1/2 a millisecond.. then back

 

i duno.. this topic just popped into my mind.. would you freeze to death even with the 1ms? would you even feel as though you were there? would you see black space?

no. Freezing to death isn't too much of a problem, because the energy would have to be lost by radiation, which is quite slow. assuming you held your breath and had earplugs in, you should be ok. It would be quite bright actually because of the masses of starlight.

ah, interesting, thx for that, so.. if you were teleported there for 1ms.. you'd still be quite warm

yeap. one concern though might be your feet. In the time you were there, the heat from your feet would probably boil away a good bit of the methane ice underneath you. (I think that methane ice is proposed on the surfaces of these planets). one ms wouldn't be much though. I have held my hand in liquid nitrogen for alot longer than that.

I have held my hand in liquid nitrogen for alot longer than that.

 

say, are you trying to get a Darwin Award or something? j/k

How long have you held it?

Holding your breath would be tough, and possibly cause damage. I don't think it would be particularly bright - not much different than a moonless night away from light pollution here on earth.

Iirc you are meant to vent as much air from your lungs as possible if sudden decompression is likely. Or maybe I dreamed that.

No, you're right. If you experience sudden decompression, the presence of air in your lungs coupled with no atmospheric pressure outside would cause them to expand quite rapidly, and hence they'd probably explode within a matter of a few seconds. Not pleasent.

a couple of seconds. I was perfectly fine.

1ms is not too bad to hold your breath for though. and moonless nights are quite bright, at least I find so anyway. perhaps I have good night vision.

the only really dangerous bit is your nose, ears, mouth and eyes since that is where the air will get out, anywhere else, the pressure is pushing against your internal organs, ribcage and so on - kind of like an inflated football. also your bottom and other assorted plumbing might need sealing too. We are only talking about a millisecond or so though, however I think that sayonara is correct in that you should expel as much air as possible first though. There is less to expand that way.

haha, naah, just mucking around. Liquid nitrogen is excellent stuff to play with and throw at people. Just don't drink it though.

You'd be fine for a couple of milliseconds, I don't think it'd leave any permanent damage at all.

yeap. I would rather be wearing strong rubber pants though.

Indeed, or some kind of tight pressure suit.

Doesn't liquid nitrogen do damage, like making a freshly picked garden flower become frozen solid that it breaks on any form of impact?

Humans are better insulated than flowers. Plus we generate heat, which helps to evaporate that pesky nitrogen.

So, if i stuck my hand in liquid nitrogen, for about a second, then pulled it out, nothing would happen???

Don't think so - just don't go and do it.

Holding some is one thing - immersing your hand in what is essentially a giant heat sink is another matter.

oh, so Radical Edawrd was talking about holding liquid nitrogen? or immersing his hand in it? 'Cause i think imay have understood wrong!

okay, so if you stayed for about 5 seconds on the planet.. you would explode..die from radiation.. i wish i were on pluto, itd be so nice and pretty

No, if you were exposed to vacuum for a length of time, you would most decidedly NOT explode. Some tissue damage might occur from your compulsion to exhale, but that's not the same thing. You's asphyxiate after a short while.

 

Your body is mostly water, the coefficient of expansion for water is really, really small, and it's only a 1 atm difference in pressure. Diving to 30 ft doesn't crush you for similar reasons.

if you put your hand in liquid nitrogen, the liquid doesn`t even touch you, the heat of your hand creates a barrier of nitrogen gas as the liquid evaporates on contact

it`s quite safe for a second, maybe two, then it gets cold as too much heat is being removed from your hand, a flower will have this effect for a fraction of a second also, but it will start off at room temperature and has a greater surface area and less mass than your hand, hence crispies in seconds
