Is gravitational time dilation different from other forms of time dilation?

Is gravitational time dilation caused by gravity, or is it an effect of the inertial force caused by gravity? Is gravitational time dilation fundamentally different from time dilation due to ...

How can we explain the position of Mann's planet when travelling on Miller's planet in Interstellar movie?

In the middle of the movie Interstellar, a crew of astronauts land on Miller's planet. For them only one day passed. For the one astronaut left on the station, 23 years passed. Imagine both look at ...

Does Earth experience any significant, measurable time dilation at perihelion?

Is there any measurable time dilation when Earth reaches perihelion? Can we measure such a phenomena relative to the motion of the outer planets?

Are gravitational force and gravitational time dilation proportional?

Particles in gravitational fields are subject to gravitational time dilation. The closer a particle is near a gravitational source, the slower is running its clock. I would like to know more about the ...

Does a clock oscillating in a friction-free hole through the center of a planet run slower than a stationary clock on the surface?

Assume a clock is dropped into a friction-free hole through the center of a symmetric, non-rotating planet, far from any other massive object. Clearly, the clock oscillates from one end of the hole to ...

Would Gravitational Time Dilation still apply between two gravitational sources?

As explained on this Wikipedia page, when an object is experiencing strong gravitational forces, time passes slower for it. If, in theory, you had two objects exerting the same amount of gravitational ...

Is there a temporal difference between planets due to the sun's gravitational field?

since the Sun generates a gravitational field it also generates gravitational time dilatation. Hence, time further from the Sun should pass quicker than in its proximity. Can we, therefore, say that ...

Is an atomic clock itself affected by gravity?

Sometimes I read that only time flows at different rates in different conditions when atomic clocks shows a different time compared to atomic clocks at altitude. But sometimes I read that an atomic ...

How do gravitons make time go slower?

In the classical view of General Relativity, time moves slower near massive objects where the gravitational field (spacetime curvature) is stronger. In the quantum view however, the gravitational ...

How can the core of the Earth be younger than the crust due to gravitational time dilation if the crust experience more force than the core?

Gravitational force decreases with depth under the surface of Earth, and at centre, the surrounding forces cancel each other out effectively making it zero and hence a body at the center of gravity of ...

How do we age if we tunneled to Earth's core?

Scenario Suppose there exists an advanced technology that can hypothetically transport living humans to study the center of the Earth, as they goes deeper underground most of the Earth's mass would ...

How can time be curved?

Time isn't a physical object, but according to Einstein's theory of gravity, mass bends spacetime towards things with mass and makes them fall. How does a physical object affect something intangible?

Slowing of time under gravity

I am not calling this gravitational time dilation because that is a relativistic effect due to the equivalence principle. Now imagine two light clocks (a clock that ticks due to light) are placed ...

Time dilation for non-physicists

Apologies in advance, as I'm not a physicist, and may use terms incorrectly. In the movie Interstellar, the planet Miller has a time dilation of one hour to seven Earth years. This has brought up ...

How does exactly time dilate in a gravitational field, and how is it judged by different inertial observers?

When I tried to answer the SE question, Clock on a pendulum, I faced an ambiguity regarding time dilation in the gravitational field. To make the argument clearer, I designed the simpler thought ...
