Obviously, any measurement of earths rotation has to involve circular logic :-) If time changed rate fast enough to explain the observed changed rate of earths rotation, we would long ago have measured drifts in other fundamental natural constants which involve time. For instance spectral emission lines from atoms in distant astronomical objects. If these other constants "magically" changed at the necessary complimentary rate, then we are back at the old joke: "If somebody took away all of reality last night, and replaced it with an exact copy, how could you tell ?" -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
