interstellar travel

Interstellar travel refers to the hypothetical movement between stars or star systems. It's a significant challenge due to vast distances and current limitations in technology. For instance, the nearest star, Proxima Centauri, is over four light-years away, meaning light takes over four years to travel there. Potential methods of interstellar travel include faster-than-light concepts, like wormholes or warp drives, which remain theoretical. Current exploration efforts, such as the Breakthrough Starshot project, aim to send small spacecraft to nearby stars using powerful lasers. Ultimately, while exciting, interstellar travel poses immense scientific and engineering hurdles that we have yet to overcome.
