When Cooper returned from a space mission to save humanity in the film Interstellar, his daughter Murphy had already grown old and was lying on her deathbed. This dramatic time gap was due to the extreme gravitational conditions near a black hole, where time flows much more slowly than on Earth. According to Einstein’s theory of general relativity, time dilates in regions of strong gravity or near-light speed travel. In fact, astronauts aboard the International Space Station (ISS) age slightly more slowly than those on Earth, gaining mere fractions of a second during long missions.

And yet, paradoxically, those who spend extended periods in space often return looking as if they’ve fast-forwarded through time. NASA astronaut Sunita Williams, for example, came back from a nine-month mission with noticeably grayer hair and deeper wrinkles. This contradiction reveals an unsettling truth about life beyond our planet: ______________________________. While time may bend in our favor, the body pays its own price. Microgravity causes muscle and bone loss, vision issues from fluid shifts, and significant changes to gut bacteria. Exposure to cosmic radiation and psychological stress further strain the body — all of which may accelerate physical aging.

As humanity sets its sights on Mars and beyond, the key question becomes not just how to travel far, but how to arrive whole. Scientists are now exploring hibernation-like states as a possible way to shield the body from the rigors of long-duration spaceflight.
