I have just recieved word that the July 5 Science will have an article on
the evidence for an 18 hour day from the pre-cambrian era. For any
young-earther's that might be lurking, evidence of a drastically more
rapid spin of the earth in the past is quite widespread.
The article is by Charles P. Sonett and Aramais Zakharian. A couple of
quotes from the note I received. This is from
UASCIENCE@LISTSERV.ARIZONA.EDU.

They go on to note that the moon will reach synchronous orbit with the
earth in 15 billion years (given the present rates of recession). That
assumes, of course that the earth and moon are not swallowed in the death
of the sun in about 5 billion years or so.
