Why does time go by faster on Earth than in space?

Why does time go by faster on Earth than in space?

This form of time dilation is also real, and it’s because in Einstein’s theory of general relativity, gravity can bend spacetime, and therefore time itself. The closer the clock is to the source of gravitation, the slower time passes; the farther away the clock is from gravity, the faster time will pass.

Are the clocks on the ISS faster?

Clocks on satellites tick faster due to less gravity, but slower due to more velocity. At the ISS orbital altitude, velocity wins out and clocks run slower. At the GPS altitude, gravity wins out and clocks run faster.

Why is time slower on the ISS?

Why? Well, according to the theory of relativity, astronauts on the ISS age more slowly due to the spacecraft’s high orbital speed. It’s called time dilation, and it means that when they return they’re a bit younger than they would have been—as if they’ve traveled into the future.

Why does time run slower on the ISS?

The ISS orbits 255 miles above the Earth at 8000 m/s, so time runs approximately 0.0000000014 percent slower. Today, GPS satellites are adjusted to account for this distortion of space time, both for the effect of time dilation from their velocity (special relativity) and their reduced gravity (general relativity), when they are put into orbit.

What would happen if the ISS was to orbit the Earth?

If the ISS were to orbit the Earth at 1.5 times the Earth’s radius (5,900 miles or 9500 km) then the effect of velocity and gravity on time would cancel each other out. At orbits greater than 5,900 miles, gravity is stronger and speeds up time, below 5,900 miles, velocity is stronger and time slows.

Why does time go faster on Earth than in space?

As per Einstein’s law of relativity time goes faster at the place where gravitational force is high .As on earth the gravitational force is more than in space. So on earth time goes faster.

Does gravity slow down the speed of the International Space Station?

ISS Science Officer Ed Lu independently confirms the ISS math, concluding the astronauts age 0.007 seconds less than people on Earth. So these two sources have figured out how the ISS’s velocity slows down its relative time, but there’s no mention of gravity in their math.
