Hello Meteorite Enthusiasts!
Hope you are all having a great week!
I was able to produce some lovely and affordable specimens of my newly
classified Eucrite NWA 10667. Please see the link below for photos. I think you
will find it has an incredible brecciated appearance.

Hi Rob, and fellow time pirates,
That's one interesting calculation and I'd have thought the latitude was
slam-dunk 90 N, because that's over 20 km closer to the center of gravity all

Turns out the combination of 1/r GR effect from mass, a latitude-dependent
quadrupole
component, and the centripetal term (special relativity) due to the earth's
rotation nearly
compensat
Hi Doug -- you are very close to the correct altitude of ~3167 km (~1.4965 *
earth equatorial
radius). I'm now working through the math to figure out the latitude on earth
where you
age the slowest. ;-) --Rob

Hi Rob and the other meteoroidal travelers,
I'd say a good mean altitude for government work would be about half of Earth's
radius, and that ought to smooth out any technicalities to gain an
understanding of the magnitudes which is what is interestng about the new
question.
A shortcut to calcu
For the satellite, it varies according to the gravity field it flies over.
Technically none exists because the gravity field is never constant. It

Hi Doug,
I think you would have come up with the correct answer if I had given
a more precise value for the clock slow down relative to a stationary
clock in deep space: it should be 0.69693 parts per billion relative to
a clock at sea-level on the earth's equator, or 60.2 microseconds per
day. I
