This has been known for over three hundred years. An elementary       textbook which discusses Newton's law of gravity should show why this       happens.              > The big bang theory postulates the matter came into       > being from a single point in space and is forever ex-       > panding.

An elementary textbook on astronomy       which discusses the cosmological red shift will give the details.              > Perhaps someone can help me with that one.

You could be thinking of the brane theories. If so Steven Hawking's       Universe in a Nutshell might give you a start. If you aren't, it looks as       if you have been watching too many third-class science fiction films.              > Following this, logic, perhaps many of these events occured       > and continue to occur (black hole?).

The earth       wasn't formed until about 9,000,000,000 years after the big bang. Gamow       wrote a book entitled The First Three Minutes, a popularisation of the big       bang theory, published in the late 1940's IIRC. This gives half the story.       Fred Hoyle wrote a popularisation in the 1960's that give the other half,       but I can't remember what its title was. A textbook on cosmology will give       you the details, but it is unlikely to be elementary.              > So, Perhaps what we would find at the center of the moon would be       > space/time rip, in which case, anything not solid enough to       > resist destruction might be sucked into an altenate dimension       > with super-pressure.

I seem to remember something in       Twilight Zone like this, but that was 40 years ago and my short term memory       isn't what is was.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
