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 much time on earth is 1 hour in space? Around eight minutes and twenty seconds.
No. The time-dilation effect of Einstein's relativity has nothing to do with space.
That's the time a celestial object rotates once around its axis. So of there's a very slow rotating object that takes a full earth year to rotate once around its axis then that 1 day is equal to an earth year. A Milky Way day, one complete rotation around its own axis, takes 225 million years.
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.
1 second in space is equal to 1 second in earth. Space time doesn't move any faster than earth time so we use earth time for all of outer 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.
It's estimated that the heart, blood vessels, bones, and muscles deteriorate more than 10 times faster in space than by natural aging.
Scientists estimate that the heart, blood vessels, bones, and muscle deteriorate about 10 times faster in space than in natural aging.
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.
Clocks on the International Space Station (ISS), for example, run marginally more slowly than reference clocks back on Earth. This explains why astronauts on the ISS age more slowly, being 0.007 seconds behind for every six months.
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...
We know the observable universe — the part we can visibly see and measure — began around 13.8 billion years ago with the Big Bang. So we know the age of the universe is finite at least from the time of the Big Bang.

In Earth's early history, a day was 23.5 hours and a year lasted 372 days.
The Earth orbits around the sun every 365.25 days.
It takes a little more than 365 days for the Earth to make a complete trip around the sun. Other planets have different orbital times.
Stars aren't visible during the sunlit hours of daytime because the light-scattering properties of our atmosphere spread sunlight across the sky. Seeing the dim light of a distant star in the blanket of photons from our Sun becomes as difficult as spotting a single snowflake in a blizzard.
People in a coma will not age like conscious people living life. Muscles weaken & emaciate. The damaged part of the brain might deteriorate as a result of inflammation to the area.
Ultimately, while astronauts' salaries are generally modest while they're working, they can still sometimes get a hefty payout once they retire from active duty. In short: no, astronauts do not get paid for life.
They won't live longer from their perspective, but observers will disagree with them on how much time has passed. Actually the astronaut doesn't experience time slowing down. From his perspective, time passes as usual. It's just that indeed he can measure time dilation by comparison with the earthlings' time.
The human body can grow up to three percent taller in space – that's about two inches for a six-foot astronaut.
Black holes are so massive that they severely warp the fabric of spacetime (the three spatial dimensions and time combined in a four-dimensional continuum). For this reason, an observer inside a black hole experiences the passage of time much differently than an outside observer.
But what of the average temperature of space away from the Earth? Believe it or not, astronomers actually know this value quite well: an extreme -270.42 degrees (2.73 degrees above absolute zero).
