Does Mass Actually Displace Space-Time, or does Mass only Distort it?
1. Question
If a planet displaces space-time within it, and if a planet distorts the surrounding space-time surrounding it, then what does the phenomena of space-time look like from within that planet?...

Do you always experience the gravitational influence of other mass as you see them in your frame?
You see a galaxy far away. That galaxy is attracting you with a certain amount of gravity. I'm wondering if the gravity influence of the galaxy on you, as measured by you, always ends up being what ...

Time dilation in a centrifuge: effect of velocity and acceleration?
An object in a centrifuge has a tangential velocity of $v = \omega r$ and a radial acceleration of $g = \omega^2 r$. By itself, the velocity would cause a time dilation of $1/\sqrt{1-(v/c)^2}$ = $1/\...

Tug of war between observers in frames with different rate of time
You have a very dense hollow sphere of matter. Observer A is inside the sphere inside a rocket. Observer B is in an identical rocket outside the sphere where the ring's gravity is negligible. They are ...

Can there be a theoretical synchronised ‘now’ moment at all points across the universe?
Einstein’s relativity rejects the notion of a universal ‘now’ moment. It underlines how the concept of ‘now’ is compromised due to time passing at differing rates in differing frames of reference, ...
