Why isn't the center of the galaxy "younger" than the outer parts?
I understand that time is relative for all but as I understand it, time flows at a slower rate for objects that are either moving faster or objects that are near larger masses than for those that are ...

Twins Paradox: Why is one frame considered to be the accelerating frame
Let me start by saying I understand the Mathematics behind the twins paradox and how it is resolved. I understand that due to the acceleration of one twin, time from their subjective experience is ...

A sees B's clock running slow and B sees A's clock running slow?
This paradox is very common it seems, in which A sees B's clock running slow and B sees A's clock running slow. Here is the question a little more concretely.
Let's say B flies by A's spaceship. If B'...

Twin Paradox Without Acceleration [duplicate]
So I've been doing a lot of reading about the twin paradox and have encountered several different explanations that strive to resolve it. First off let me start by saying general relativity is not an ...

The twin paradox and positively curved space
I'm reading about the twin paradox in special relativity - if there are two identical twins, one of whom who sets off in a high speed rocket to a planet, and then heads back, will find the twin who ...

Twin paradox with one twin in orbit, one in radial free-fall
Many questions on Physics SE relate to the twin paradox, but I did not find any that ask this specific question. Suppose that object A is in a circular orbit around a spherically symmetric, non-...

Time dilation for a clock in orbit
Suppose that we want to compute the total time dilation for a clock located in an orbiting satellite relative to the clock in our cell phone on the ground.
Consider two different approaches below.

Gravitational Time Dilation vs Acceleration Time Dilation
I might be a little dense to this subject, but I would like to ask a question relating to this one
( Is gravitational time dilation different from other forms of time dilation? )
but asking if this ...

The Time Freezing Room - Theoretically possible?
Imagine a room in your basement with a very special property: The time inside this room runs 60 times faster compared to the outside world. That means when you enter the room and spend there 1 day ...

Question about position dependence of time dilation?
I found this picture from a physics stack exchange question on time dilation: Time dilation all messed up!
I am now returning to it a few weeks later and was wondering if I am correctly interpreting ...

How relativistic Doppler effect interact with time dilation?
Knowing that a body in motion experiences time dilation, "also" knowing when two objects travel at a great speed away from one an other, both observers experience the others clock as moving ...

How close should you get to speed of light, in order for time to be dilated?
Recently I was watching Carl Sagan's Cosmos: A Personal Voyage. In episode 8 ("Journeys in Space and Time") there is a scene presenting the idea of time dilation, due to traveling close to the speed ...

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 there a location in the universe with the minimum rate of time dilation?
According to general relativity, time dilation occurs due to strong gravitational fields and high relative velocities, causing time to pass more slowly compared to observers in weaker gravitational ...

Why is light affected by time dilations in space-time curvatures
My previous question on this site gave me an answer to what affects light - space warping or time warping. The answer is- both. But what now doesn't make sense to me is why light is affected by time ...
