According to our current understanding of physics, it is not possible for objects with mass to travel faster than the speed of light in a vacuum, as postulated by Einstein's theory of relativity. The theory of relativity states that as an object approaches the speed of light, its mass would become infinite, requiring an infinite amount of energy to continue accelerating.
If we consider a hypothetical scenario where an object could travel faster than light (FTL), it would lead to several consequences that are not yet fully understood. One such consequence is the violation of causality, which means that the order of cause and effect events could be reversed. This would result in paradoxes and contradictions in our understanding of the universe.
Regarding the question of time, according to the theory of relativity, as an object accelerates and approaches the speed of light, time dilation occurs. This means that time slows down for the object relative to an observer at rest. However, it's important to note that this time dilation effect only applies to objects traveling near the speed of light, not specifically to FTL travel.
In summary, based on our current scientific understanding, it is not possible for objects with mass to travel faster than light. If such a possibility were to exist, it would lead to several fundamental challenges and contradictions in our understanding of the universe.
