Wormhole

A wormhole is a theoretical shortcut connecting distant points in spacetime, functioning like a tunnel through the universe's fabric. Imagine folding a sheet of paper with two dots on it; a wormhole would be like creating a tunnel between those dots, reducing the travel distance. While rooted in Einstein's theory of general relativity, wormholes remain speculative, with no experimental evidence yet. If they exist and can be stabilized, they could potentially allow near-instantaneous travel across cosmic distances, offering fascinating possibilities for future space exploration and understanding the universe's structure.
