How long is 1 hour in space?

There are 24 * 60 minutes in a day (without taking into account the imperfection of the natural world, the Earth and the Sun). If our definition of a day were indeed based on the full rotation of the earth around the earth's axis—a rotation of 360 degrees—then a day would be 23 hours 56 minutes and 4 seconds long. It takes 940 million kilometers to go once in our orbit around the Sun on a path around the Sun.... [+] That's why our day is longer than 23 hours and 56 minutes, that is, the time required is 360 degrees. Time on the Moon flows about 0.66 parts per billion faster than on Earth because it is not in such a strong gravitational field.

For example, on the International Space Station, time passes more slowly, delaying by about 0.01 seconds for every 12 Earth months that have passed. Depending on our position and speed, time may appear to move faster or slower than others in another part of spacetime. Time is measured differently for an identical twin and a twin left on Earth.

In your question, an astronaut returning from space travel at "relativistic speeds" (where the effects of relativity begin to show - generally at least one tenth of the speed of light) would be younger on his return. Stayed on earth. Scientists recently noticed for the first time that astronauts age more slowly during simulated long space travel than if their feet were on planet Earth. If you were born at sea level, you have already lived about 360 hours a year, or 2160 hours of your life.

If you were on an extremely fast planet in space, like in the movie Interstellar, you could lose 7 years on Earth every hour. You may have seen Christopher Nolan's film Interstellar, here getting close to a black hole causes time on another planet to slow dramatically (one hour on this planet equals seven Earth years). Its proximity to a supermassive black hole has also caused a huge time dilation, with one hour on a distant planet equaling seven years on Earth.

When you're outside the expansive International Space Station, you're effectively a separate celestial body, a tiny satellite on Earth, spinning at 17,500 miles per hour. The word "space" also has a vague definition, but it usually means "outside the Earth's atmosphere," which means that if you go up enough, you'll be there.

A person in this position in deep space would have a watch running for one hour, while this person calculated our clock to run 59 minutes 59.9974 seconds. You travel through time at the same speed almost all the time, whether you're watching paint dry or wanting to spend more time visiting a friend out of town. Long ago, a NASA astronaut attempted a spacewalk on Earth five or more times in a huge pool. I hope you get some important information. Thank you.
