Connection between kinetic and gravitational time dilation [duplicate]
I am learning about relativity and am interested in time dilation. I now exactly understand where the formula of kinetic time dilation comes from and wondered about gravitational time dilation. I have ...

When two neutron stars collide to form a black hole, for how long will last the emitted signal from the very vicinity of the new formed event horizon?
When two neutron stars collide they may form a black hole which is not a supermassive black hole but it should provoke that outside its newly formed event horizon photons are emitted as a consequence ...

Light Travel Delay in Kerr Render Engine
me and a friend are working on a render engine which can visualise Kerr Black Holes with a volumetric accretion disk and astrophysical jet. So far, this is what we got;
As you can see, we have the ...

Why don't two accelerated clocks behave like two clocks in a gravitational field?
If we immerse two clocks in a gravitational field at different altitudes (with the approximation that both heights share the same g for equivalence to be true), the falling and Schwarzschild observers ...

Relativistic Time-Keeping and Sharing
Suppose there are 2 ships which keep time using atomic clocks. The atomic clocks are the same build so it is know that the two keeps keep proper time at the same rate. Suppose that the two ships ...

Question about gravitational time dilatation
For $g_{00} = 1 - 2GM/c^2r$ , the time interval $\Delta T$ measured in a stationary frame at a distance $r$ from the source and the time interval $\Delta t$ measured by a frame at $r= \infty$ are ...

Is there gravitational time dilation as we look further out into space (and therefore further back in time)?
There is a formula for gravitational time dilation which relates the slowing of time to a changing force of gravity.

Acceleration and gravitation are locally equivalent ? I find not
In a gravitational field, the above and below clocks do not run at the same rate.
The acceleration equivalent means that the simultaneity changes. During acceleration there would be a gravitational ...

How would a clock with hands behave if half of it is outside a black hole and half inside? [closed]
I am thinking of a clock moving close to the speed of light at a tangent to the event horizon so it doesn't fall in instantly Would the time like spacetime inside the black hole be reflected in the ...

Hafele–Keating Experiment. What are the forces acting on the moving clock?
According to the Hafele–Keating Experiment, time dilation is the reason for the differences between the earth bound clock and the moving clock.

How do we know the assumptions of the Schwarzschild solution are valid?
The Wikipedia article on the derivation of the Schwarzschild solution (https://en.wikipedia.org/wiki/Derivation_of_the_Schwarzschild_solution) lists 4 assumptions. The second of which is:
A static ...

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 ...

How can I calculate gravitational time dilation between two planets? [duplicate]
I am writing a school paper and chose to do it about gravitational time dilation. I wanted to calculate the time that passed on Mars when 1000 years on Earth went by. (probably a tiny difference). I ...

Quantum Theory and Time [closed]
I read somewhere that quantum theory requires absolute time and not a dynamic time as described in relativity. Can anyone confirm this and further describe in laymen's terms what quantum theorists ...
