The discussion centers around the effects of high-speed flight on aging, specifically examining how time dilation might impact an airline pilot's age relative to ground-based colleagues after a career of flying. The scope includes theoretical considerations of time dilation due to velocity and gravity.
Participants generally agree that the effects of high-speed flight on aging are trivial, though there are nuances regarding the direction of travel and the interplay of gravity and velocity that remain unquantified.
The discussion does not resolve the specific impacts of gravity and velocity on time dilation at cruising speeds and altitudes of commercial aircraft, nor does it clarify the assumptions behind the calculations presented.
This discussion may be of interest to airline pilots, physicists, and individuals curious about the implications of relativistic effects in everyday scenarios.
They do, and that's a good point, although as you also note, that doesn't change the conclusion that in any case it is a trivial amount. What you've pointed out, in fact, makes it even more trivial.jackwhirl said:Gravity and velocity both play a role, don't they? And fight each other in this case, iirc.
