What will happen if you put a massive object in spacetime?

Imagine two very massive objects, such as black holes. If those objects were to collide, they could potentially create an extreme disturbance in the fabric of spacetime, moving outwards like the ripples in a pond.

Why do massive objects distort spacetime?

Anything with mass—including your body—bends this four-dimensional cosmic grid. The warp, in turn, creates the effect of gravity, redirecting the path of objects that travel into it. The strength of gravity depends on the size of the space-time warp.

Does light bend space-time?

Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time.

How does curved space affect time?

The curvature of spacetime (not just space) is responsible for gravity. Literally, near heavy objects, the “future direction” points slightly down. So anything that moves forward in time will find its trajectory pointing down slightly.

How do objects move through space and time?

Even objects “at rest” (in a given reference frame) are actually moving through spacetime, because spacetime is not just space, but also time: apple is “getting older” – moving through time. The “velocity” through spacetime is called a four-velocity and it is always equal to the speed of light.

Why does a stationary object not follow the curvature of spacetime?

Only “freely” falling particles follow Spacetime curvature available to them. So, when you see a stationary object not following Spacetime curvature, it’s because an external force is preventing it from going to it’s inertial trajectory… Means, it’s not in “Free Fall”.

What determines the curvature of the universe?

The Universe is out there, waiting for you to discover it. The spacetime curvature around any massive object is determined by the combination of mass and distance from the center-of-mass.

What is the difference between action-at-a-distance and spacetime curvature?

Action-at-a-distance was here to stay, but Newton’s “infinite-range force through static space” was replaced by spacetime curvature. more severely curved space — run at a different rate than ones in a shallower, less-curved portion of space.
