ty up there. All great stuff.

Yes! time and gravity change depending where you are. How close you are to the center of the earth, etc. Fly in a plane a lot and you live a tiny tiny bit longer ’cause you age less. it’s too small to matter but still interesting. GPS units have Einstein’s relativity plugged into them because the GPS satilite clocks are running at a different speed than the receivers here on earth ’cause of less gravity up there. All great stuff. “
