When we gaze up at the night sky, we’re not just looking at stars and planets we’re peering into the past. The light from distant galaxies takes millions, sometimes billions, of years to reach us. This cosmic time-travel effect is a powerful reminder of the immense scale of the universe and the extraordinary challenge of crossing it. Even reaching the closest star, Proxima Centauri, would take tens of thousands of years with current spacecraft. Now imagine trying to travel to another galaxy, like Andromeda, which is nearly 2.5 million light years away.
At that scale, conventional physics reaches its limits. If humanity ever hopes to journey across the cosmic ocean, we’ll need more than faster engines we’ll need to rewrite the rulebook of physics itself.
