## Do clocks go faster in space?

The clocks on the satellites are orbiting Earth at a speed of 14,000 kilometers per hour and are moving much faster than clocks on the surface of Earth. According to Einstein’s theory of relativity, the clocks on the satellites are ticking more slowly than Earth-based clocks by about 7 millionths of a second per day.

## How much does time speed up in space?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

## Can time be slower on another planet?

yes, minimally. the density of earth is not too uniform and the speed of time depends on how far you are away from large masses (and how fast you move relative to the maximum relative speed). makes for some millisedonds per year for of time dilation for satellites in low earth orbit.

## How does time work in outer space?

The general theory of relativity suggests that space-time expands and contracts depending on the momentum and mass of nearby matter. … Four gyroscopes were pointed in the direction of a distant star, and if gravity did not have an effect on space and time, they would remain locked in the same position.

## Is an hour in space 7 years on Earth?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

## How long is 1 second in space?

It is defined as the distance that light travels in free space in one second, and is equal to exactly 299,792,458 metres (983,571,056 ft).

Use in astronomy.

## How long can a human live in space?

Astronauts need space suits to stay alive. You could only last 15 seconds without a spacesuit — you’d die of asphyxiation or you’ll freeze. If there’s any air left in your lungs, they will rupture.

## How did Einstein prove relativity?

Einstein postulated three ways this theory could be proved. One was by observing the stars during a total solar eclipse. The sun is our closest strong gravitational field. Light traveling from a star through space and passing the sun’s field would be bent, if Einstein’s theory were true.
