Think of a 3-D grid. that cover's every millimetre of our universe. One of the lengths is time-space, one is mass and energy and the other one is unknown.
The Space-Time continuum is the gathering of the three space dimensions (x,y,z) and the time dimension (t) used to localize everything and every interactions in our universe.

This depends upon the Theory of Everything (TOE) used to describe the observable physics of the universe.
In Extreme Relativity:
The observation of the connected systems of causal relationships forms the base of space/time.
The supposition is that since there exists instantaneous properties (quantum entanglement - electromagnetics, and gravitational aberration - gravity) that the foundations of observable physics are superimposed on an instantaneous foundation. This unifies all forms of physics.
This create an environment supporting extreme relativity.
In this environment space is infinite but relativistic. Look up at a star at night. The star is many millions of years since the photon began travelling. From your position move over some small amount, or a large amount, and you will see the same photons. No matter how close you get to each point of reference, you have the same causality; the same magnitude assertion for what you observe.
This is all based upon the causal properties of functioned quantum entangled systems.

Gravity is a force, not a bend in spacetime.
Look at this websitewww.spacetimemodel.com It says that mass is really just a 4d volume of spacetime displacing and therefore warping the spacetime around it and so the answer is all mass displaces and so warps spacetime.

There is no such thing as gravitational force. Mass curves spacetime and stuff moves through spacetime in straight spacetime paths. The effect of this is what we call gravity. The more the mass the greater the curvature of spacetime.

Time doesn't affect space. Space and time are the same thing in relativity; that's why we call it spacetime. Mass affects spacetime and spacetime affects mass.
Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
