According to our current understanding of physics, specifically Einstein's theory of relativity, it is not possible to travel faster than the speed of light in a vacuum. In relativity, the speed of light, denoted by "c," is considered to be an absolute speed limit in the universe.
As an object with mass approaches the speed of light, its energy and momentum increase dramatically, making it increasingly difficult to accelerate further. As an object with mass approaches the speed of light, its relativistic mass increases, requiring a greater amount of energy to continue accelerating. At the speed of light, an object with mass would require an infinite amount of energy to reach or surpass that speed, which is considered unattainable.
Moreover, as an object accelerates closer to the speed of light, time dilation occurs. Time appears to slow down for the moving object relative to an observer at rest. This effect becomes more significant as the object approaches the speed of light, and at the speed of light, time dilation would be infinite.
Attempting to exceed the speed of light would lead to several consequences, including violation of causality, where events could be observed to occur before their causes, as well as the breakdown of other fundamental principles of physics.
Therefore, based on our current understanding, it is not possible to go faster than the speed of light while remaining within the framework of relativity.
