It's not a bad idea, Pete, but unfortunately the time dilation is really minimal unless you get up
to a substantial fraction of the speed of light. For instance, even at solar system escape velocity
at earth's distance from the sun (42 km/sec), a meteoroid's clock would be running at about
10 parts per billion slower than that of a stationary rock. (Additional note: due to general relativity,
a clock on a meteoroid would be running about 0.6 parts per billion *faster* than a clock at the
earth's surface, but that is more than made up for by the time dilation due to special relativity.)
Extra-credit question for the mathematically inclined: at what velocity relative to the earth
would a meteoroid have to travel to have its clock stay in sync with a clock at the earth's
surface? :-) --Rob

Subject: [meteorite-list] age of meteorites
greetings to all,
my background is in electronics. everything deals with either C or C2.
Einstein states that nothing goes faster than the speed of light and that as you approach the speed of light, things get older slower.
So this meteorite in it's travels is going at a rate that is a subtantual percentage of the speed of light. Has anyone taken this into consideration when placing an age on the meteorite?
Just a thought to tickle the old brain cells!!
