No I don't think I said that. What I said was, there were different epochs and different things happened during those epochs. As I understand things, the laws of Physics in each epoch came into effect simultaneously. Both heat and light are different parts of the electromagnetic spectrum which differ only in frequency and wavelength. As soon as Maxwell's equations are valid for one they must be valid for the other.Mr. beenthere plz mention those few cases where light exists without heat and vice versa
Absolute zero is a theoretical extreme with complications in the bizarre world of quantum mechanics, therefore it is unlikely ever to (read as never) be achievable in practice. Even the Bose-Einstein Condensate is factionally above absolute zero.and all objects we know of are above absolute zero

Oh, and the Chicken came first!
Well a photon doesn't intrinsically have heat, but energy which can be transfered to produce heat. As an example, think of your porridge in your microwave oven, the microwave has energy which is transfered into lossy materials heating the food volumetrically.Dave...Had you given any thought to the definition of light as that which eminates from the atom from the moving of an electron from one level to a higher level and/or the same electron falling back. The movement of the electron is the result of energy being added or taken away and I'm not sure whether the amount of energy would be enough to necessarily create any heat. If what I stated is true and the electron movement can be without heat...then we have light without heat...???LINDSROTH@yahoo.com
Its ok, I wasn't challenging your original statement regarding absolute zero, more-so adding some further information.You are correct, Dave. I wasn't trying to hint that absolute zero was an achievable temperature, rather that nothing was at absolute zero, therefore everything has both heat and light.
Thanks for the clarification!
