According to our current understanding of physics, it is not possible to travel through time by moving faster than light. The theory of relativity, formulated by Albert Einstein, sets a universal speed limit in the universe, which is the speed of light in a vacuum. This speed limit, denoted by 'c,' is approximately 299,792,458 meters per second.
As an object with mass accelerates, its energy and momentum increase, requiring more and more energy to continue accelerating. As an object with mass approaches the speed of light, its energy and momentum would become infinite, which is not physically possible.
Moreover, the theory of relativity also introduces the concept of time dilation. It states that time can appear to pass differently for objects that are moving relative to each other. As an object approaches the speed of light, time dilation becomes significant, causing time to pass more slowly for the moving object relative to a stationary observer.
However, even with time dilation, it does not allow for "time travel" in the sense of freely moving back and forth through time. It only affects the perception of time for the moving object and does not enable travel to past or future events.
The topic of time travel is still an active area of scientific research, and theories such as wormholes, black holes, and spacetime curvature are explored in the realm of theoretical physics. However, currently, there is no scientific evidence or widely accepted theory that supports the possibility of traveling through time by exceeding the speed of light.
