Does mass compress space?

As space-time is in effect the one entity, space and time itself gets “smaller” as an observer gets closer to the centre of a large mass.

Does mass displace spacetime?

When on exist in the same region as the other, the total energy of the region increases. This means that each energy makes up a certain percentage of the total energy. A change in the percentage along a distance means that there is an energy gradient of each energy. Mass does not “push” on spacetime.

Does gravity stretch or compress space?

It is here that Einstein connected the dots to suggest that gravity is the warping of space and time. 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 is the relationship between space-time and mass?

Einstein discovered that there is a relationship between mass, gravity and spacetime. Mass distorts spacetime, causing it to curve. Gravity can be described as motion caused in curved spacetime .

What is mass in spacetime?

We are taught that mass warps spacetime, and the curvature of spacetime around mass explains gravity – so that an object in orbit around Earth, for example, is actually going in a straight line through curved spacetime.

What force is explained by general relativity?

It was conceived by Einstein in 1916. General relativity is concerned with gravity, one of the fundamental forces in the universe. Gravity defines macroscopic behaviour, and so general relativity describes large-scale physical phenomena.

Why does mass bend space?

When a smaller mass passes near a larger mass, it curves toward the larger mass because spacetime itself is curved toward the larger mass. The smaller mass is not “attracted” to the larger mass by any force. The smaller mass simply follows the structure of curved spacetime near the larger mass.

Does gravity expand space?

In addition to slowing the overall expansion, gravity causes local clumping of matter into stars and galaxies. Once objects are formed and bound by gravity, they “drop out” of the expansion and do not subsequently expand under the influence of the cosmological metric, there being no force compelling them to do so.

Is space and mass related?

Completely interchangeable. And finally, Although energy and mass are related through special relativity, mass and space are related through general relativity. You can define any mass by a distance known as its Schwarzschild radius, which is the radius of a black hole of that mass.

What is distorted in space-time based on the general theory of relativity What causes it to be distorted?

As he worked out the equations for his general theory of relativity, Einstein realized that massive objects caused a distortion in space-time. The object would press down into the fabric, causing it to dimple.

Does general relativity lie on special relativity?

Hence, General Relativity lies on Special Relativity. If the latter were proved to be false, the whole edifice would collapse. In order to understand General Relativity, we have to define how mass is defined in classical mechanics.

Is gravity the warping of space and time?

The equivalence principle tells us that the effects of gravity and acceleration are indistinguishable. In thinking about the example of the cylindrical ride, we see that accelerated motion can warp space and time. It is here that Einstein connected the dots to suggest that gravity is the warping of space and time.

How does gravity affect the passage of time?

Gravity slows the passage of time. Similar to how the passage of time is changed under special relativity, general relativity predicts that massive objects will also dilate time. The more massive the object, the more noticeable the effect.

Does space-time get smaller near a singularity?

Dimensions (x,y,z) also get tighter near a singularity. As space-time is in effect the one entity, space and time itself gets “smaller” as an observer gets closer to the centre of a large mass. Can this shrinkage constitute a compressibility of space-time?
