Calculate mass from time dilation
Hi not a physicist in any way so was wondering if I know the age (time passed) and mass of an one object and the age (time passed) of another object, can I calculate its mass?
So Object 1 is Earth:
...

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 ...

Is time dilation due to relative velocity equivalent in principle to time dilation due to relative gravitational strength?
Is time dilation due to relative velocity and relative gravitational strength equivalent? That is, similar to Einstein's thought experiment where an observer in an enclosed capsule with no windows ...

Does Gravity Causes Time Dilation?
Let's say there are 2 people, A and B. They both are at the sea level. A gets higher than B. Does time moves faster to A then B? (Does height -in other words gravity- causes Time Dilation?)

Time dilation in the center of the earth [duplicate]
The time dilation seem to slow time in stronger gravitational fields.
Lets say we put a person with a clock in the center of the earth.
It will feel no gravity since it's pulling from every direction ...

Gravitational time dilation and power beaming
Consider this thought experiment that kept me awake for far too long last night.
Two spacecraft are located near a black hole, and their relative positions are such that, due to the gravitational time ...

Are we gaining or losing time as our planet revolves around the Sun?
I understand that the Earth (or someone standing on our planet) will undergo time dilation due to a number of reasons compared with someone hovering in interstellar space. I would like to focus on two ...

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 ...

If an astronaut orbits earth, can both Time Dilation and Gravitational Time Dilation affect it? [duplicate]
I am very new at all of this stuff and this one thing bugs me very much...
If an astronaut is orbiting earth, it should be experiencing Time a bit faster than those on earth, correct?
Well then ...
