Space is unimaginably vast, stretching beyond anything most humans can easily comprehend. Scientists estimate that the observable universe is about 93 billion light-years across—an expanse so immense that even light, traveling at 299,792 kilometers per second, would need billions of years just to cross it. This sheer scale makes even our solar system seem almost…

Einstein’s theory of relativity reveals that time is not absolute; it varies based on speed and gravity. Astronauts aboard the International Space Station (ISS) experience time differently than those on Earth. Orbiting at approximately 7,700 meters per second, they age about 0.005 seconds less over six months compared to people on Earth. (en.wikipedia.org) This phenomenon,…

Embarking on a journey beyond Earth’s atmosphere exposes the human body to unique challenges. The microgravity environment, increased radiation, and confined living conditions aboard spacecraft and space stations can lead to a range of physiological and psychological changes. These adaptations underscore both the marvels and obstacles of extended life in space. Understanding these effects is…
