Exploring the Possibility of Antigravity
The concept of antigravity, popular in science fiction, is not feasible under current physical laws, as it would require negative energy, which doesn't exist in our universe. General relativity shows that gravity is a result of spacetime curvature caused by mass and energy, and all known entities have positive energy. While antigravity remains impossible, artificial gravity can be achieved through constant acceleration, such as in a rotating spacecraft, to simulate Earth's gravity for long space journeys. Addressing the health issues from prolonged zero-gravity exposure should be prioritized for future space travel.
