AI Thread Summary
Gravity influences time by causing it to slow down in stronger gravitational fields, as described by general relativity. The equation t = t_f sqrt(1 - 2GM/rc^2) illustrates this relationship, where M is mass, r is the distance from the center of mass, and c is the speed of light. This effect is significant for practical applications, such as adjusting GPS satellite clocks and understanding time dilation for those living at different elevations. While the fundamental reasons involve complex concepts like spacetime tensors and relativistic effects, the core takeaway remains that gravity affects the passage of time. Overall, the relationship between gravity and time is a fundamental aspect of how the universe operates.

If gravity slows time, how and are they linked?
 
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

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
