Does the clock tick faster when falling? [duplicate]
I just read this answer that explains that the time dilation due to the gravity and the time dilation due to velocity are the same thing.
Does that mean that, if I fall from the top of a skyscraper on ...

Question about time dilation and what an observer sees
This is a soft question I was discussing with a friend. Suppose a portal opens up (I know this is fiction) but for the sake of argument, let's suppose something like that happens. And the observer can ...

How is time dilated in a gravitational field?
I picture a box that contains a particle that travels back and forth at the speed of light. One round trip is a unit of time. We place this box on the surface of a large planet. The particles run ...

Why would spacetime curvature cause gravity given that the value of gravitational time dilation is so small?
In this question, mpv provides the clearest explanation of the operation of gravity in his answer:
The apple moving first only in the time direction (i.e. at rest in space) starts accelerating in ...

How does gravitational time dilation affect matter?
Einstein successfully melded together space and time into one entity called spacetime in his General relativity theory and gave us further insight into how matter affects spacetime.
John Wheeler said “...

How does gravity affect time dilation? [duplicate]
I understand that the faster you move through space the slower you move through time, but how does gravity play a role in that?

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?

Is time dilation reduced when two opposing gravitational forces equally pull on an object? [duplicate]
(I apologize for my naivete in advance.)
The Lagrange points around the earth and the moon provide a semi-stable space to put objects because the gravitational pull (combined with centripetal force) ...

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 ...

Do freefalling clocks within a small region of spacetime undergo gravitational time dilation?
I have several times seen explanations of gravitational free fall (eg, of a small object toward earth with no air resistance) that begin with the following claim about the particles of the free-...

Bell's paradox but with acceleration caused by a uniform gravitational field rather than rocket engines
Bell's paradox has in the past been the topic of quite heated discussions. It is posed in the context of a silk thread connecting two identical rockets whose engines are ignited at the same instant. ...

Gravitational Time Dilation and Equivalence Principle
My question relates to page 118 of these notes, which is reproduced below for your convenience. Specifically, I have difficulty understanding the line "This shows that time slows in a region of ...
