... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

God Science Forum Message . ... The Destropic Principle . ... Abstract: The “Destropic Principle” is an argument that establishes that every universe is equiprobable, and the possibility of life is not a more special feature than any other. This opposes to the “anthropic principle” when it is used to argue that there is a necessity for a divinity, or multiple universes, in order to explain the configuration of our universe, particularly, the capability of harboring life. ... www.astronomy.net . ...
