Does Mass Actually Displace Space-Time, or does Mass only Distort it?
1. Question
Given the plethora of space-time illustrations, there is a sense that space-time is actually being displaced by mass, (planets). But on its face, this doesn't really make sense because ...

How does a curvature in time equate to Newtonian gravity? [duplicate]
I often read that a curvature in time (the rate at which clocks tick) near a massive object, is considered to be the source of Newtonian gravity.
This got me wondering, does General Relativity use the ...

The apparent dilatation of time in General Relativity
Maybe this a dumb question, but, is the gravitational dilatation of time caused because a particle travelling through a geodesic in a curved space-time must cover a larger distance than the one ...

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 ...

Is it possible to observe Shapiro time delay if gravitational attraction is zero, but time dilation, as part of spacetime curvature is not zero?
I understand it might not be very clear what I mean by the title so I will try describe it using simpler (but less accurate words). Unfortunately I cant use math to describe it. Sorry about that - I ...

Time dilation at a point between two spherical masses that nearly touch
I need to apologize for asking the question trough very "blunt" and fantasy scenario, but I believe it will help me to understand better how the connection between mass and time works (well not mass ...

How is time affected by the bending of space-time?
By Newton's Laws, we can calculate the effect of gravity, but he didn't give the actual reason for gravity. I searched the internet for it, but all the answers have this "bending of space-time" stuff. ...

Can everything be described without anything needing to actually "bend"? [closed]
Is space bending because gravity actually causes small particles to move differently? If large source of gravity is somewhere are particles extending towards it, creating a "bend" in space? So "bend" ...
