According to our current understanding of physics, it is not possible for objects with mass to travel faster than the speed of light. The theory of special relativity, which has been extensively tested and confirmed through various experiments, sets an upper limit on the speed at which information or physical objects can travel in a vacuum—this limit is the speed of light.
As a result, even if there were a hypothetical method for traveling faster than light, it is not currently within our technological capabilities. The immense amount of energy required to accelerate an object to such speeds is beyond our current technological capabilities, and it would violate our current understanding of physics.
Furthermore, traveling at speeds close to the speed of light would still present significant challenges. Time dilation, as predicted by special relativity, means that time would pass more slowly for the traveler compared to those in a different reference frame. This means that even if we were able to approach the speed of light, significant amounts of time would pass for those remaining on Earth while we traverse great distances. This would make interstellar travel impractical for human lifespans and communication.
It's important to note that our understanding of physics is constantly evolving, and there may be future discoveries or advancements that challenge our current limitations. But based on our current understanding, the speed of light remains an insurmountable barrier for practical interstellar travel.
