Jeg surfede lidt og fandt dette på en side, men er det rigtigt?
Jeg troede kun man havde påvist at tid afhænger af hastighed
og endnu ikke tyngdefelt, men det er måske underforstået via
relativitetsteorierne..?
"We know that gravity distorts time by virtue of the fact that if we take
two devices which measure minute variations in time, and we keep one at sea
level and take the other to a high altitude, when we recompare them, they
reflect different times. The difference in this passage of time is caused by
the fact that a gravitational field weakens the further you get from the
source, and of course in this instance, the source of the gravitational
field is the earth. So the one device which was taken to the high altitude
was exposed to a less powerful gravitational field than the device which we
kept at sea level. One device used to make measurements like this is an
atomic clock and the most recent atomic clock is supposed not to vary more
than 1 second in every 1 million years, that's how precise it is. So the
effect of a gravitational field on space/time is something that we've been
able to observe but not experiment with. This is due to our inability to
generate a gravitational field."
