## What is the fabric of space and time?

spacetime
The biggest lesson from Einstein’s general theory of relativity is that space itself isn’t a flat, unchanging, absolute entity. Rather it’s woven together, along with time, into a single fabric: spacetime. This fabric is continuous, smooth, and gets curved and deformed by the presence of matter and energy.

Is spacetime really a fabric?

There is no “fabric” to it. Spacetime isn’t “made of” any material or substance, i.e. it is an immaterial, insubstantial thing.

### How do you explain time and space?

The general theory of relativity suggests that space-time expands and contracts depending on the momentum and mass of nearby matter. The theory was sound, but all that was needed was proof. That proof came courtesy of NASA’s Gravity Probe B, which demonstrated that space and time were indeed linked.

Can space/time fabric be broken?

According to Einstein’s general relativity, it is impossible to tear the fabric of space. They performed a series of mathematical manipulations called flop transitions, which means that the original Calabi-Yau space is flopped over into a new configuration.

## Why is it called the fabric of space-time?

Any mass in a region of spacetime will lead to a distortion / curvature of space-time. Empty spacetime is flat, whereas spacetime in the presence of masses is curved due to gravity. Scientists treat spacetime as a smooth ‘fabric’ which is distorted by presence of mass. Thus the term the fabric of space and time.

What is meant by the fabric of space?

In Einstein’s theory space and time is single entity called spacetime. We treat spacetime as a smooth fabric which is distorted by presence of energy. Thus the term the fabric of space and time. The term fabric is used to help us visualize how spacetime works in GR.

### Why is it called spacetime?

Nowadays, when people talk about space-time, they often describe it as resembling a sheet of rubber. This, too, comes from Einstein, who realized as he developed his theory of general relativity that the force of gravity was due to curves in the fabric of space-time.

Why is it called space-time?

This new reality was that space and time, as physical constructs, have to be combined into a new mathematical/physical entity called ‘space-time’, because the equations of relativity show that both the space and time coordinates of any event must get mixed together by the mathematics, in order to accurately describe …

## What is the concept of space?

Space is the boundless three-dimensional extent in which objects and events have relative position and direction. The concept of space is considered to be of fundamental importance to an understanding of the physical universe.

Why is space a 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 a black hole a tear in the fabric of space?

While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.

What does the fabric of space mean?

## Is space-time a fabric?

Einstein called it a distortion of space caused by large astronomical objects such as stars. Now the media has everyone calling space-time a fabric. A curvature of the fabric of space-time as the cause of gravity.

Why does space-time look like a rubber sheet?

Nowadays, when people talk about space-time, they often describe it as resembling a sheet of rubber. This, too, comes from Einstein, who realized as he developed his theory of general relativity that the force of gravity was due to curves in the fabric of space-time.

### What is the fabric of the universe?

The fabric of the Universe, spacetime, is a tricky concept to understand. But, thanks to Einstein’s [+] general relativity, we’re up to the challenge. The biggest lesson from Einstein’s general theory of relativity is that space itself isn’t a flat, unchanging, absolute entity.

What is the theory of space-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. Who discovered space-time?
