What does it mean to warp spacetime?

A time warp can be thought of as anything that disrupts the flow of time by making it go faster or slower. This effect is known as gravitational time dilation, and it results from distortions in space-time.

What is the elasticity of spacetime?

Considering the elasticity of spacetime we can refer to a very interesting idea: the elastic dark energy of the universe as the energy of the initially compressed, elastic spacetime of the actual universe (like an elastic strain fluid). The work of Riess and Perlmutter establishes that the universe is accelerated.

Can you stretch space-time?

Spacetime can be stretched as much as you want. Indeed, at the singularity in a black hole the stretching becomes infinite, though I’d guess most of us think some quantum effects become important near the singularity and prevent it actually becoming infinite.

What is stretching the universe?

The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand “into” anything and does not require space to exist “outside” it.

What is spacetime fabric made of?

The fabric of spacetime is made of density, pressure and flux of energy in all of its forms. Without energy there would be no spacetime.

Why is space expanding?

Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space. As a result, this form of energy would cause the universe to expand faster and faster.

What does space expand into?

The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.

Are space and time the same thing?

Back in the 1800s, there was space and there was time. Both were described by coordinates, and in some mathematical formalisms, both appeared in related ways. But there was no notion that space and time were in any sense “the same thing”.

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?

What causes the curvature of space time?

Massive objects — like the Earth, sun or you — create distortions in space-time that cause it to bend. These curves, in turn, constrict the ways in which everything in the universe moves, because objects have to follow paths along this warped curvature.

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.
