If gravity slows time, how and are they linked?
 

Discussion

Physics news on Phys.org
How :
t = t_f sqrt(1 - 2GM/rc^2) M is the mass, r is the distance from centre of mass

Why :
simple answer - because that's what general relativity says.
complex answer - because that's the way the universe works.
 
Yep that clears it aaaaall up.

Lol

If you want to work out how much to adjust your GPS satelite clock, or how much longer you will live on the top floor of the apartment - then the equation tells you.
As to why, there are answers involving space time tensors, kerr metrics, relativistic frame dragging etc - but they pretty much come down "because it does" but with more maths.
 
Ok it's complicated.
Thanks
Chris
