How would you age in space?

In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.

How do we age in space?

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. First, time appears to move slower near massive objects because the object's gravitational force bends space-time.

How long is 1 hour in space?

The time dilation on that planet—one hour equals 7 Earth years—seems extreme. To get that, you'd apparently need to be at the event horizon of a black hole. Yes.

What happens if you stay in space for 5 years?

Astronauts who have stayed in space for long periods have problems with their circulation and eyesight. That's in addition to losses in bone and muscle tissue. Kelly has collected fluid samples and undergone rigorous medical testing to document these changes over the course of his trip.

Do you live longer in space?

Both athletes & astronauts had a lower risk of premature death than the general population: Study. Although space travel exposes astronauts to forms of radiation that are uncommon on Earth, and that are linked to cancers and heart problems, a US study suggests this doesn't significantly shorten their lives.

Do you age 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.

Is time slower on Earth than in space?

Time is measured differently for the twin who moved through space and the twin who stayed on Earth. The clock in motion will tick more slowly than the clocks we're watching on Earth. If you're able to travel near the speed of light, the effects are much more pronounced.

How close would a human get to the Sun?

You can get surprisingly close. The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up. That said, an astronaut so close to the sun is way, way out of position.
