Coldest place in the universe discovered. Boomerang Nebula ~1.1°C above absolute zero. - Polidicks

[QUOTE=Chernobyl426;42672607]Still learning about it & and trying to manage it with shitty educational resources. Definitely interested in it.[/QUOTE] If you want help with understanding it or improving your knowledge base, don't hesitate to drop me a PM :)

[QUOTE=Chernobyl426;42672607]Still learning about it & and trying to manage it with shitty educational resources. Definitely interested in it.[/QUOTE] also thermodynamics, the science of energy transfers, with pertinence to heat, gives the background to explain the properties of the OP nebula every particle in the universe, every single piece of matter regardless of size, vibrates and moves around at some intensity. more movement indicates a greater amount of energy held by the particle. now when a number of particles are bound to a volume, or each other, and are interacting with each other, bouncing around, and knocking against themselves, the friction between the particles releases some of their energy as heat. when a gaseous mass like a nebula is very, very, very cold, it's because the (absurdly massive number of) particles are barely registering on the grand scale of particle motion. their thermal energy is extremely low--since the point of the Kelvin scale is to have a "floor" at the absolute lowest imaginable temperature, 0K, a nebula with a reading of 1.1K is impressively cold.

[QUOTE=Falubii;42661626]Is that a serious question? I really can't tell when people are joking in these threads. You'd die very quickly.[/QUOTE] "very quickly" is the biggest understatement of the universe

[QUOTE=J!NX;42678743]"very quickly" is the biggest understatement of the universe[/QUOTE] Not really: [quote]A rough estimate is that a human will have about 90 seconds to be recompressed, after which death may be unavoidable.[2][3] The low pressure outside the body causing rapid de-oxygenation of the blood (hypoxia) is the primary reason for unconsciousness within 14 seconds.[4] In 1965 Jim LeBlanc lost consciousness after approx 15 seconds of being depressureised.[5][/quote] [url]http://en.wikipedia.org/wiki/Space_exposure[/url]

[QUOTE=J!NX;42678743]"very quickly" is the biggest understatement of the universe[/QUOTE] You probably wouldn't freeze to death actually.

[QUOTE=LarparNar;42678779]Not really: [url]http://en.wikipedia.org/wiki/Space_exposure[/url][/QUOTE] thats for our space yes, but in absolute zero I imagine you would turn into ice extremely quickly [QUOTE=Falubii;42678815]You probably wouldn't freeze to death actually.[/QUOTE] if you don't then shattering would be the worst of your worries :v:

[QUOTE=J!NX;42678975]thats for our space yes, but in absolute zero I imagine you would turn into ice extremely quickly [/QUOTE] Temperature doesn't matter as much as the quantity of matter. A handful of sparse atoms, no matter how low in temperature, won't be felt by a human body. You'd be better off being in contact with 50000 atoms at 10K than being in a vat of water at 273K.

[QUOTE=J!NX;42678975]thats for our space yes, but in absolute zero I imagine you would turn into ice extremely quickly[/QUOTE] Doesn't matter in a near vacuum, there's very few particles there to steal energy from the particles in your body, so few it probably wouldn't even have any effect within 90 seconds.

I imagine that in space, if we somehow managed to fix all the other lethal environmental conditions, you'd probably die of heatstroke since your body can't dissipate heat well enough sooner than you'd die of hypothermia.

[QUOTE=acds;42679114]I imagine that in space, if we somehow managed to fix all the other lethal environmental conditions, you'd probably die of heatstroke since your body can't dissipate heat well enough sooner than you'd die of hypothermia.[/QUOTE] This. There's a reason spacecraft are mostly white/reflective. Anything else would absorb too much heat from the Sun and create a whole shit-ton of cooling issues.

[QUOTE=Kirbyfactor;42661452]Wonder how it feels to be there.[/QUOTE] Probably feels kinda like chewing 5 gum.

[I]♩You're as cold as the Boomerang Nebula♩[/i] [i]♩You're willing to sacrifice our dust♩[/i]

[QUOTE=LarparNar;42678779]Not really: [url]http://en.wikipedia.org/wiki/Space_exposure[/url][/QUOTE] that's pretty interesting actually. I thought death was near instantaneous after space exposure. thought your head would blow up due to the pressure difference? I take back all of my angry words in dead space 3 where Isaac [sp]is thrown out into space without his helmet, thought he'd die[/sp]

How can they be so sure this is the coldest place in the entire Universe? What's stopping there from being a place with ~1.0 C above absolute zero?

I don't think that was the astronomers words. They probably meant coldest place discovered so far.

The question at hand [I]is[/I].... How plausible is creating a freeze ray

[QUOTE=J!NX;42678743]"very quickly" is the biggest understatement of the universe[/QUOTE] In space there's so few molecules that you'd probably loose more heat to thermal radiation. And if you were in the sun you'd probably overheat in a pretty short timespan. Neither is what will kill you, though.

Seems like a cool place to stage a Doctor Who episode. 'We're going to the coldest place in the universe!'

[QUOTE=Laserbeams;42665795]Light doesn't freeze, it doesn't have a temperature. Only matter can have temperature, if it's not made of molecules it can't be hot or cold[/QUOTE] Matter doesn't necessarily need a temperature. At a hypothetical state of absolute zero, that is, the total absence of heat energy, electrons would still move within an atom, photons would still propagate as waves, gluons would still whizz around inside hadrons, etc. You only speak of there being absence of motion in tangible things (interestingly, fundamental particles, such as electrons, photons and gluons don't have a "size" - it's part of the definition of a fundamental particle); so atoms wouldn't move at 0K, but the electrons within would.
