The concept of time travel, often explored in science fiction, is rooted in Albert Einstein’s theories of relativity. These theories revolutionized our understanding of time and space, suggesting they are not fixed but can be altered by speed and gravity. According to Einstein, time moves slower for objects in motion or under strong gravitational influence. This means that traveling at high speeds, like near the speed of light, could allow someone to experience time differently than those on Earth, effectively traveling into the future. This phenomenon was observed with astronaut Scott Kelly, who aged slightly less than his twin after spending time in space. Einstein’s insights into the nature of time and gravity continue to intrigue scientists and fuel discussions about the possibilities of time travel.
