Quick Answer: How Does Gravity Warp Time?

How does the warping of space cause gravity?

Gravity, Einstein asserted, is caused by a warping of space and time—or, in a language we physicists prefer, by a warping of spacetime.

The Earth’s matter produces the warpage, and that warpage in turn is manifest by gravity’s inward tug, toward the Earth’s center..

Is it possible to travel back in time?

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! We travel one year in time between birthdays, for example.

Does NASA have a warp drive?

IXS Enterprise is a conceptual interstellar superluminal spacecraft designed by NASA scientist Dr. Harold G. White, revealed at SpaceVision 2013, designed for the goal of achieving warp travel. … The Alcubierre drive uses exotic matter (not to be confused with antimatter) to travel faster than light.

How does gravity distort time?

This effect is known as “gravitational time dilation”. … Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.

How long is 1 year in space?

Why is that considered a year? Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. It’s not exactly this simple though. An Earth year is actually about 365 days, plus approximately 6 hours.

Why does Time never stop?

Cortês and Smolin suggest that the universe is made up of a series of entirely unique events, never repeating itself. Each set of events can only influence events in the next set, so the arrow of time is built in.

Can time be bent?

Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Also, under Einstein’s theory of general relativity, gravity can bend time. … When anything that has mass sits on that piece of fabric, it causes a dimple or a bending of space-time.

Can gravity be manipulated?

The better news is that there is no science that says that gravity control is impossible. First, we do know that gravity and electromagnetism are linked phenomena.

Does time cause gravity?

So time slows down in a gravitational field while objects fall down. … Both the slowing of time and acceleration occur simultaneously and don’t cause each other: it’s just the Natural state of gravity.

Do astronauts age faster?

Telomeres and aging Our study proposed that the unique stresses and out-of-this-world exposures the astronauts experience during spaceflight – things like isolation, microgravity, high carbon dioxide levels and galactic cosmic rays – would accelerate telomere shortening and aging.

How long is 1 hour in space?

That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour, while that person calculated that our clock ran for 59 minutes, 59.9974 seconds.

Can time machine be made?

To create a time machine would require negative energy, and quantum mechanics appears to allow only extremely small regions of negative energy. And the forces needed to create an ordinary-sized region with time loops appear to be extremely large.

What can warp space time?

The Alcubierre metric defines the warp-drive spacetime. It is a Lorentzian manifold that, if interpreted in the context of general relativity, allows a warp bubble to appear in previously flat spacetime and move away effectively faster than lightspeed.

Can time be stopped?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” The practice is, admittedly, a bit more difficult. … To phrase this tenet in a more friendly manner, it means that a light beam’s speed remains unchanged even if the observer moves relative to it.

Has anyone been lost in space?

Soyuz 1 dooms cosmonaut: The first fatal accident in a space mission befell Soviet cosmonaut Vladimir Komarov, whose problem-plagued Soyuz 1 capsule crashed onto Russian soil in 1967. … The resulting drop in pressure also exposed the crew to the vacuum of space — the only human beings to ever experience such a fate.
