Why does mass make curvature in spacetime? [duplicate]
According to Einstein's general relativity theory, matter with mass makes curvature in spacetime. The greater the mass, the curvature in spacetime will be greater.
My questions:
Why will mass make ...

How exactly does matter cause spacetime curvature? Is it the result of another force?
In general relativity matter is said to curve spacetime. But I am still not sure how to physically visualize it. Is it an expansion or contraction? Is space being pulled in or is it being pushed out? ...

If gravity is curvature of space why are more massive objects "heavier?"
How does curved space explain why a denser object of the same shape and volume feels heavier?

When we say energy curves spacetime, which is the cause and which is the effect?
I read that energy is one of the parameters (physical properties) that contributes to the curvature of spacetime, then there is the math proof using General Relativity. I was wondering because common ...

Does Electrostatic potential energy bend Space-time? [duplicate]
Okay, there are various questions.
First, "matter and energy bends space-time" does this mean any form of energy can bend space-time?
Does theory of relativity assume that there is no other form of ...

Is there a known mechanism for mass-energy distorting spacetime?
I’ve been really interested in learning about the mechanisms behind physical phenomena that go beyond just learning to manipulate the equations and give a physical intuition about HOW something ...

Does kinetic energy warp spacetime?
My interpretation of GR leads me to think that energy (namely kinetic) also adds to the curvature of space-time. Which, has raised a thought experiment. If a $10000$ kg ship closely passed a $1$ kg ...

Do mass and motion affect space-time differently?
Mass is said to create curvatures in space-time thereby creating gravity, yet technically the smallest movements, even on Earth, create gravitational waves. Are there different "types" of disturbances ...

What (& why) exactly does a massive body curve/bend in General Relativity?
So, in General Relativity a massive body bends, curves the spacetime continuum...
But WHAT exactly is it that "thing" that gets curved? What exactly is empty space? Does it have a real, physical ...

Intuition for why mass and energy curve the space-time fabric and for why this relationship is linear?
The force of gravity does not exist
I understand(-ish) that, following general relativity, an apple falls onto earth, not because there is a force pulling earth and the apple toward each other but ...

Why mass & energy bend spacetime? [duplicate]
I understand how light / matter bend spacetime but I'd like to understand WHY. Is there some kind of interaction?

Mass curves spacetime, there is no such thing as gravity?
It is said that there is no such thing as gravity. Mass/energy curves spacetime and a body follows this curvature so gravity is basically the geometry of spacetime. If there is no force of gravity why ...

Why does two masses with energy attract each other?
I have heard that every mass attract another mass with a force directly proportional to the multiplication of their masses and inversely proportional to the square of distance between them, but newton ...

Can energy bend space? [duplicate]
I know mass bends the space around it and I also remember matter can be converted into energy and vice versa, so my question is: can energy interact with space in a similar fashion as matter does?
