What is the spacetime fabric?

Space-time can be thought of as a ‘fabric’ in which the objects of the Universe are embedded. Those objects – stars, planets, black holes – make space-time curve in upon itself, just as an elastic fabric holding a ball would do. The more massive the object, the deeper the curve – the same as in a fabric!

Is it possible to bend the fabric of space and time?

Spacetime, however, is the combined concepts of space and time into a four-dimensional continuum. You may have even seen spacetime portrayed as a fabric, manipulated by energy. If spacetime can be bent, Beacham continued, it’s theoretically possible that time can be bent.

How is time and space related?

Einstein, however, introduced the concept of a fourth dimension — time — that meant that space and time were inextricably linked. The general theory of relativity suggests that space-time expands and contracts depending on the momentum and mass of nearby matter.

What causes the bending of spacetime?

Gravity is the curvature of spacetime Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.

What means bending time?

To bend time means to travel from one point to another on the space-time continuum. which means moving through time and space.

What is the fabric of space-time?

The fabric of space-time is a conceptual model combining the three dimensions of space with the fourth dimension of time. According to the best of current physical theories, space-time explains the unusual relativistic effects that arise from traveling near the speed of light as well as the motion of massive objects in the universe.

What is curved spacetime?

Curved spacetime often gets called the aether of Einstein. But it is a little misleading, since the aether of old is out the window. To once again quote the http://itss.raytheon.com/cafe/qadir/aphyrel.html: ” ….First of all, space-time is not a fabric. Space and time are not tangible ‘things’ in the same way that water and air are.

How does spacetime affect objects outside of spacetime?

So, to more explicitly answer your question, spacetime is all around – there is nothing outside of spacetime, and there is merely the objects within it. These bend and twist spacetime, therefore affecting other objects. Hope this helps; I’d be glad to clarify further if necessary.

What is the difference between space-time and a rubber sheet?

A rubber sheet is two dimensional, while space-time is four dimensional. It’s not just warps in space that the sheet represents, but also warps in time. The complex equations used to account for all of this are tricky for even physicists to work with.
