What Is Gravitational Time Dilation and How Does It Work?

AI Thread Summary
Gravitational time dilation occurs when a clock positioned in a stronger gravitational field runs slower than a clock in a weaker field, a phenomenon confirmed by experiments. This effect is closely related to gravitational redshift and blueshift, which describe how light waves change frequency in varying gravitational fields. The concept is rooted in the principles of general relativity, emphasizing the relationship between gravity and time. Numerous discussions and resources are available in specialized forums for deeper understanding. Gravitational time dilation is a fundamental aspect of modern physics with practical implications in technologies like GPS.
Astronomy news on Phys.org
If you have two precise clocks, and you position one of them further away in the gravitational field, say some tower if your experiment is here on earth, it will run faster then the other one. It is been experimentally verified on numerous occasions.

Gravitational time dilation is inseparable from gravitational redshift/blueshift.

You have many threads about it in SR/GR forum.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Thread 'Visible light Over Large Distances'

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
