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.

Do you biologically age slower in space?
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.
Why do you age slower at the speed of light?

How much slower do you age in space?
Scientists estimate that the heart, blood vessels, bones, and muscle deteriorate about 10 times faster in space than in natural aging.
Do you age during time dilation?
Albert Einstein’s 1915 theory of general relativity proposes an effect called time dilation. This means that you would age slightly slower or faster depending on the gravitational field, an effect that can be measured with atomic clocks located at different elevations.
Do you age slower if you travel at the speed of light?
Changes to time and distance. Perhaps one of the most famous effects of special relativity is that for a human moving near the speed of light, time slows down. In this scenario, a person moving at near light speed would age more slowly. This effect is called time dilation.
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.
Do you age faster in Mars?
Humans taking the 40 million mile trip to Mars may age faster than people remaining on Earth, according to scientists, who are hunting for a way to stop it happening.
Do you age while in a coma?
the cellular mechanism for ageing has been associated with progressive shortening of telomere length on the ends of each chromosome with each cell cycle.. in the contect of this, a coma wouldnt necessarily keep you young, but you would age just the same.
Why do we age biologically?
Cells are the basic building blocks of the body. Your cells are programmed to divide, multiply, and perform basic biological functions. But the more cells divide, the older they get. In turn, cells eventually lose their ability to function properly.
Do you age 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.
Does gravity affect aging?
The conclusion is that gravity accelerate biological aging, not chronological aging.
Do you age slower in a black hole?
In short, a person near a black hole will age slower compared to someone far away from the black hole. This is because the passing of time is slowed down due to the extremely strong gravitational field near the black hole and thus, any physical aging processes will also happen slower.
Does time stop at the speed of light?
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.
What happens if someone dies in space?
Short Answer: Depending on the circumstances of your death, you would be frozen, dried out, slowly rotting, or decomposing normally, in which case the rest of the crew would need to find a way to store or dispose of you.
Do you age faster higher up?
Using a pair of the world’s most precise clocks, physicists at the NIST, discovered that simply going upstairs will make you age faster. If one of the clocks was moved just a foot higher, then it ran a little bit faster – albeit by a tiny fraction of a second, they found.
Why do you age faster at higher altitudes?
The NIST experiments focused on two scenarios predicted by Einstein’s theories of relativity. First, when two clocks are subjected to unequal gravitational forces due to their different elevations above the surface of the Earth, the higher clockโexperiencing a smaller gravitational forceโruns faster.
Do people age faster at higher elevations?
Technically yes, relative to an observer on Earth, a person at higher altitudes will age faster.
Do pilots age quicker?
Chou did the math, and it turns out that frequent fliers actually age the tiniest bit more quickly than those of us with both feet on the ground. Planes travel at high enough altitudes that the weak gravitational field speeds up the tick rate of a clock on board more than the high speeds slow it down.
What did Einstein say about time travel?
For example, physicist Albert Einstein’s theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.) much more slowly than an observer at rest.
What is twin paradox theory?
In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more.
Do bodies decompose in space?
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.
How much do astronauts get paid?
Astronauts who work for civilian agencies like NASA earn a base salary of $104,898 per year. However, their salaries can increase to $161,141 per year.
Is Interstellar a paradox?
The ending of Interstellar seems to present a “bootstrap paradox.” In short, this is a type of time paradox in which a chicken sends an egg back in time, which egg then becomes that chicken.
Would you age faster on Jupiter?
On Jupiter you would age only slightly more slowly than on the earth.
