# Is each level of a group of systems representative of gravitational time dilation?

• NWH
In summary, time would continue to tick faster and faster as you move further away from each gravitational source but the effect would be very small.

Okay, this is a hard question to phrase, so I apologise if I'm off course somewhere. One could say our world around us is built up in different levels. We live down here on a planet, orbiting around a star, flowing around a galaxy and so on. What I'm wondering is how time would be effected through each of these levels if we took a (hypothetical) measurement at each one. Time up in space is faster than it is on Earth. Now, if we escaped further out of the sun's gravitational field into deep space and stopped at rest, would time tick even faster relative to Earth because we're further away from the sun? Now, what if we went even further and escaped out of the gravitational field of the Milky Way into deep, deep space. Would time continue to tick faster and faster relative to the Earth until we started entering another gravitational field?

Anyone?

Yes, but the effect would be very small as you get far away from each gravitational source. Gravitational time dilation is noticeable only when you're reasonably close.

Oh, I see. Okay, thanks...
