If we could hypothetically travel faster than the speed of light, the concept of distance and travel time would change significantly. However, it's important to note that according to our current understanding of physics, objects with mass cannot travel faster than the speed of light.
For reference, the closest star to Earth (other than the Sun) is Proxima Centauri, located approximately 4.24 light-years away. This means that it takes light around 4.24 years to travel from Proxima Centauri to Earth.
If we assume a hypothetical scenario where we could travel at a speed faster than light, such as using a fictional FTL technology like warp drives or wormholes, the concept of travel time becomes uncertain. Since traveling faster than light would involve bending or warping space-time, the distance between two points could effectively be shortened or bypassed altogether.
In science fiction, FTL technologies often allow instantaneous or near-instantaneous travel between distant locations. However, it's important to remember that these concepts are purely speculative and not currently supported by our scientific understanding.
Until we discover or develop new physics or technologies that challenge our current understanding, the speed of light remains an ultimate speed limit, and the travel time to reach our closest star, Proxima Centauri, would be limited to the time it takes light to make the journey, which is approximately 4.24 years.
