    If the sun is constantly adding energy to earth at any givin time, and space is a vacum that does not contain particles with which to tranfer energy to, then why doesn't the earth, or why hasn't it already, superheated due to its inability to disperse energy to another source? Energy cannot be created or destroyed, right? Even if the earth is efficient at absorbing the suns energy, and making things like coal, oil, and plants (in part), I can't imagine that it could prevent radiant heat from being emitted and constantly sent into the amosphere.

    Am I missing something?

    radiant heat from being emitted and constantly sent into the amosphere.
    I guess then it loses the radiant heat (infra red) out into space.

    Two words, but anyway what other possible explnanation could there be? The think the greenhouse effect only slows the process down.

    How about time travellers? Their energy of their machine and the traveller increases the entropy of the past (or future).

    But then again it effects their present too, so :?.

    All of that energy changes form. Alot of the energy is turned into chemical energy by photosynthesis. some (not much) escapes back into space. The poles actually act to cool down the earth to, along with the ocean. Heat can be trapped in watter particles as they are evaporated, and then they cool down in the upper hemisphere. Where did all of that energy in petroleum come from? Stuff like that stores energy in a chemical form that in heat form would warm the planet.

    I agree with the rest, but:
    The poles actually act to cool down the earth to, along with the ocean. Heat can be trapped in watter particles as they are evaporated, and then they cool down in the upper hemisphere.
    The only way for the water vapor to cool down is by losing energy to other colder particles untill eventually they lose there energy to space in the form of infra red radiation. Also, in relation to the ice caps cooling the planet, that heat still stays part of the planet as the ice then melts if the heat energy stays there. Maybe you meant the ice caps reflect some of the sunlight back out into space, which is true.

    Just because space is a vacum doesn't mean it completely void of everything. light travels through space which is a form of radiation and there are particles in space. Like the particles that are realeased from comets and from exploding stars.

    In fact I don't think that there is a place in the universe where there is a perfect vacum a.k.a. nothing. Nothing doesn't exist, if that makes sense.

    Since there is a hole in the ozone at the south pole couldn't energy escape back into space through there? Just me wondering a bit.
