I don't know as 'escape' is the best term for it though. It's not like the planet vents it into space. It definitely moves around though, good old thermodynamics keeping us above absolute freezing. All the more reason it was funny that article I read while living in Pacific Grove out in Cali that mentioned the weather being "predictably unpredictable." As far as I can tell because it was less foggy some days, and more foggy other days? temperature was 50s to 60s regardless so that's the only 'unpredictable' I could come up with. Pretty sure it's still like that there right now. And to be fair we didn't have as many truly cold days this winter (or so far this swinter) as in years past here. |

well, we do have convection heating :> lol but let's not nitpick on words >n> technically speaking it escapes the area, doesn't mean it leaves the atmosphere XP i'd say the weather is normally predictably unpredictable, though :Y how often is the weatherman right? slightly more than the groundhog on groundhog day, but i'd say, not significantly XD ahh, so overall winters are still warmer than usual in many places (excepting the areas that got hit with the most horrible snow stroms recently) |

Eventually all heat radiates out into space though. We get radiation heat from the sun, and we radiate out a 'lower quality' heat (i.e. more entropy). The greenhouse effect makes it so that we need to be hotter than before to radiate out as much heat as we get from the sun (plus a bit extra from nuclear fission within the earth and left-over heat from its formation). |

And because it's tenuously related and I still find it funny, I present the Three Laws of Thermodynamics as explained to me by David Morgan-Mar (here)

I'm not sure that third one is correct.. Besides, recently scientists reached a temperature below absolute zero http://www.theepochtimes.com/n2/science/gas-atoms-cooled-below-absolute-zero-333044.html (So much for absolutes) |

Heh. Absolutes described by humans are silly. Like we know. Still, that is definitely interesting. |

i never quite understood why people made such hype over absolute zero...but as i understand it, the part that's impossible to reach is knowing beyond a shadow of a doubt that there are no digits past the decimal point and THAT is what is unreachable since you either get a value below it or above it, but never absolutely at that point... (sometimes scientists obsess over the most ridiculous things....ok, very often) |

I'm still a little, well kind of a lot, unsure of the science saying they passed below absolute zero and actually have this 'infinitely' hot gas - as my understanding of 'absolute zero' that means we still can't get there. Because at absolute zero all motion, even sub-atomic, ceases. And that sounds nothing at all like what those scientists are saying they got. |

It's quantum mechanics, it's weird. This article might explain it better. Basically maximum temperature = maximum entropy; if you force atoms to an even higher energy level, then entropy has to decrease, because there are fewer states for them to occupy. So you can reach a point where heating (adding energy) decreases entropy, the opposite of what happens at normal (positive) temperatures. |

i still can't imagine subatomic particles ever sitting still 100% but people always invent new ways to look at things XD |

Due to Heisenberg's uncertainty principle if a particle was absolutely still, it would have to be everywhere at once (or perhaps, rather, it has an equal probability of being anywhere at all). Great for fast travel If you want to get somewhere quickly, don't move!

At least as long as you don't care where it is you end up. |

are you thinking...6 feet under? cuz...we all end up there eventually, anyway :Y inescapable, really.... ...but i guess slow and steady wins the race? ^^; Edited by Snofox Kari, Mar 29 2013, 01:01 AM.

No, he means that indeterminacy literally means you don't know where you end up. Though considering the universe at large it will likely not be a place hospitable to life. But it's more likely to be somewhere in space rather than under the surface of a planet. |
