That is very probable. I see that there is something wrong with everything, even my being here.Chris Peterson wrote:There's something very wrong with that concept...beyond wrote:... to obtain a brief period of perpetual motion...
Why do you say that? Did I say something that offended you? If so, it wasn't deliberate; I just found it amusing to think of something that was perpetual and at the same time occurring only briefly.beyond wrote:That is very probable.

No. I don't even think that would be possible especially following the rules of the forum. There could have been a period after the initial forming of the Universe where it would have appeared as though the Universe was a perpetual motion machine.......Until Entropy was realized and burst that Bubble. Now perpetual motion only shows up in the thoughts and dreams of men.chris peterson wrote: did i say something to offend you?
Hi! If you were referring to my statement; I don't recall saying that the universe was a machine. Rather; I said that it seems that it is in perpetual motion. I'm sorry if I misled you.beyond wrote:No. I don't even think that would be possible especially following the rules of the forum.

Everything is in motion, and always will be. It is the nature of the Universe. But that sort of perpetual motion is entirely different than the usual sense of the phrase, meaning a sort of machine that can do work without requiring an energy source, generate more energy than it consumes, or the like.orin stepanek wrote:Hi!

Yeah, but the Big Freeze is approached asymptotically. It will take forever for the Universe to reach absolute zero, so there will always be motion.neufer wrote:http://en.wikipedia.org/wiki/Big_Freeze wrote:

You did not mislead me. My Bad. I was thinking of a very young Universe and misspoke (i think) in replying because of what i was thinking of.orin stepanek wrote:Hi!
