According to our current understanding of physics, specifically the theory of relativity, it is not possible to travel faster than the speed of light in a vacuum. In special relativity, the speed of light in a vacuum, denoted as 'c', is considered an absolute speed limit. As an object with mass approaches the speed of light, its energy requirements become infinite, making it impossible to reach or exceed that speed.
If we were to consider the hypothetical scenario of an object traveling faster than the speed of light, it would lead to several consequences that violate the principles of relativity. One of these consequences is the violation of causality, which refers to cause and effect relationships. If an object were to travel faster than light, it would be possible for events to occur in which the effect precedes its cause, leading to logical inconsistencies.
Additionally, as an object with mass accelerates towards the speed of light, its relativistic mass increases, requiring more and more energy to continue accelerating. This increase in mass leads to an increase in the object's inertia, making it increasingly difficult to achieve higher speeds.
It's important to note that the theory of relativity has been extensively tested and confirmed by various experiments and observations. To date, there is no empirical evidence to support the existence of particles or objects traveling faster than the speed of light within the framework of relativity.
