Is it true that time dilation in a universe with no gravity could not be calculated without knowing how much mass is present in the universe?
Looking for a quick clarification on something. I am a layman and I have been trying to find out how much time dilation would exist if there was no gravity anywhere, and ignoring what seem to be ...

Understanding consequences of spacetime relativity
If I understood right, time flows slower where there is more gravitational force (or to be more precise, as it was pointed out to me, where gravitational potential is lower), compared to where there ...

What causes time warping in the space-time?
I was reading through some blogs/articles and watching youtube videos that explained to non-physicists such as myself - how time warping or a gradient in time flow around any object can create gravity....

Spacetime effects on human scale objects?
For a human standing upright on the earth, gravity would have a different value at the feet than at the head, and gravity influences the flow of time. Does the difference in the flow of time cause any ...

Why would time behave differently in different parts of the galaxy? [closed]
I watched Interstellar and I got really confused around different time thing. How can it be possible at all that time is different at different places in the universe?
Please explain.

How is time defined in time dilation?
It appears that there are two different concepts of time dilation (in my amateur point of view):
Time delation due to relative velocity. Let‘s say a second is measured by the time it takes for light ...

Time dilation : Hourclock on Jupiter
Time slows down on Jupiter because of higher gravity, but Hourclock(sand clock) run faster due to higher g. If I am correct than how?

Instead of warping spacetime, can gravity be represented by locally varying time rates?
Instead of thinking of gravity as mass warping spacetime, could it be thought of as mass warping only time, whereby time would advance at faster rates at locations where more mass is present?

Can we travel forward in time like this?
An object in spacetime warps it and creates like a pit. If the object had such a huge mass and gravity that the pit edges were touching or were anyway very close would it be possible to skip a portion ...

Center of Earth effects Time [duplicate]
I was watching this documentary about time:
https://www.youtube.com/watch?v=v99-S4_IvVg
It shows that gravity does effect time, and the higher the force the slower time will pass and slower you will ...

Where does time fit into Einstein's theory space and time?
I have been looking at and researching Einstein's theory space and time more and cannot find an explanation for where time fits into his fabric of spacetime. I can see how space fits into it via ...
