What can warp space-time?

What can warp space-time?

Large objects such as the Sun and planets aren’t the only masses that warp the fabric of space-time. 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.

What phenomenon can warp space-time according to general relativity?

According to general relativity, the curvature of space-time is determined by the distribution of masses, while the motion of masses is determined by the curvature.

Is warping time possible?

Well, possibly, but it’s not likely. “The general consensus is that these really bizarre solutions of general relativity that include time machines are almost certainly impossible in the real universe,” said Benjamin Shlaer, a research fellow in physics at the University of Auckland in New Zealand.

Can you distort space-time?

Since matter carries energy (via Einstein’s famous relation that energy is mass times the speed of light squared), such objects will have a gravitational field and so they will distort space-time. So one way in which a charge or a magnet will distort space-time is by virtue of its matter.

Who can bend space-time?

Space-time can be bent by mass, but we know famous Einstein equivalence principle between mass and energy : E=mc2. So seems that energy,- including moving object’s kinetic energy can bend spacetime too.

Can we alter space-time?

“If space can be bent, then spacetime can be bent.” One proposed method of time travel is via wormholes. “We know that space can be bent. If space can be bent by, say, gravity, then spacetime can be bent,” Beacham said.

Can time be warped by gravity?

Yes, time goes faster the farther away you are from the earth’s surface compared to the time on the surface of the earth. This effect is known as “gravitational time dilation”. It is predicted by Einstein’s theory of General Relativity and has by verified multiple times by experiments.

What did Einstein mean by curved spacetime?

Gravity feels strongest where spacetime is most curved, and it vanishes where spacetime is flat. This is the core of Einstein’s theory of general relativity, which is often summed up in words as follows: “matter tells spacetime how to curve, and curved spacetime tells matter how to move”.

Why did Einstein not believe that general relativity Geometrizes gravity?

Einstein never thought of GR as “geometrizing” the gravitational field. He actively considered such an interpretation of the formalism, and rejected it. Instead, Einstein saw GR as unifying gravity and inertia. The unification manifested in the geodesic equation.

Why does mass warp space time?

A mass that accelerates through a changing gravitational field will radiate energy away, and that radiated energy is a rippling through the fabric of space known as gravitational waves. Without matter or energy there any longer, there’s nothing to maintain the curvature to space.

What is warp theory?

To bend time and space, large amounts of energy are needed. For the time being, that remains an indisputable fact. But if we had a spaceship that could bend time and space, we could potentially travel faster than the speed of light. That’s what’s referred to as a Warp Drive.

What cosmic body can distort space-time?

Gravity is the curvature of spacetime It is here that Einstein connected the dots to suggest that gravity is the warping of space and time.

Do magnets bend space-time?

By reanalyzing the basic equations of general relativity, a researcher has discovered that magnetic fields tend to flatten and stiffen the fabric of space-time. The finding might force cosmologists and astronomers to reexamine how magnetic fields have shaped the evolution of the cosmos.

Why can’t we reverse time?

Going back in time is unmixing; it can’t be done. The universe can’t be ‘unmixed’. What this means, ultimately, is that time only exists because the Big Bang created a universe that started out ordered. If the universe was disordered from the beginning, there would be nothing left to mix and time would not exist.

Why does time distort in space?

According to the theory, matter and energy distort space-time, curving it around themselves. ‘Frame dragging’ theoretically occurs when the rotation of a large body ‘twists’ nearby space and time. It is this second part of Einstein’s theory that the Nasa mission has yet to corroborate.

How does time distort space?

Relativity says that when two observers are in different frames of reference, each observer considers the other one’s perception of time to be distorted. We’ll also see that something similar happens to their observations of distances, so both space and time are distorted.
