## Why do clocks in space run slower?

That’s because of time-dilation effects. First, time appears to move slower near massive objects because the object’s gravitational force bends space-time. Public Domain The phenomenon is called “gravitational time dilation.” In a nutshell it just means time moves slower as gravity increases.

## How is 1 hour in space equal to 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.

## Does time run slower on the ISS?

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.

## Is time slower on the moon?

Time passes about 0.66 parts per billion faster on the Moon than on Earth, due to not being in as strong a gravity field.

## How long is 1 hour in space?

Answer: 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 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. Addressing this issue requires a more thorough exposition on Special Relativity, the first of Einstein’s two Relativity Theories.

## 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.

Unit light-hour 60 light-minutes = 3600 light-seconds 1079252848800 m 1.079×109 km

## How long is a day in space?

She previously worked on a Hubble Space Telescope instrument team. The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis.

The Earth is the only planet with an approximately 24-hour day.

Planet Length of Day
Neptune 15 hours, 57 minutes
Pluto 6.4 Earth days
