Intergalactic travel refers to the hypothetical journey between galaxies, which are vast collections of stars, planets, and other celestial bodies. Currently, our technology allows us to explore only our own galaxy, the Milky Way, and reaching other galaxies, such as Andromeda, would require advancements far beyond our current capabilities. The challenges of intergalactic travel include immense distances, as the nearest galaxy is about 2.5 million light-years away. Concepts like warp drives or wormholes are often discussed in science fiction as potential methods for faster-than-light travel, but these ideas remain theoretical and have not been realized in practice.
