The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. 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).
How long is 1 second in space?
Unit of: length
SI units: 299792458 m
How long is 1 hour in space?
One hour on Earth is 0.0026 seconds in space.
How long is 1 hour in space for Earth?
there are no hours in space. an hour is a not too convenient unit that is 1/24th of one revolution by the earth on its axis of rotation. Earth gravity is not that strong so it should only dilate time by a little bit.
Can you survive 1 second in space?
Could you really survive outer space without a suit? Yes, for a very short time. … At most, an astronaut without a suit would last about 15 seconds before losing conciousness from lack of oxygen. (That's how long it would take the body to use up the oxygen left in the blood.)
How long is 1 year in space on Earth?
How long is 1 year in space compared to Earth? **One year in space would be 365 days /1 year on earth…..
How is 1 hour 7 years in space?
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 day in space?
The definition of a day is the amount of time it takes an astronomical object to complete one full spin on its axis. On Earth, a day is 23 hours and 56 minutes, but other planets and bodies rotate at different rates….The Earth is the only planet with an approximately 24-hour day.

Do you age slower in space?
We all measure our experience in space-time differently. That's because space-time isn't flat — it's curved, and it can be warped by matter and energy. … 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.
