According to our current understanding of physics, nothing can travel faster than light in a vacuum. In the theory of special relativity, proposed by Albert Einstein, the speed of light in a vacuum, denoted by "c," is considered to be the ultimate speed limit of the universe. The theory suggests that as an object with mass accelerates, its energy and momentum increase, and as it approaches the speed of light, its mass would effectively become infinite, requiring an infinite amount of energy to continue accelerating.
This concept is encapsulated in Einstein's famous equation, E = mc², where "E" represents energy, "m" represents mass, and "c" represents the speed of light. As an object with mass approaches the speed of light, the equation shows that its energy would tend toward infinity.
Therefore, based on our current understanding, it is not possible for anything with mass to reach or exceed the speed of light. However, it's worth noting that there are some theoretical concepts, such as the idea of wormholes or hypothetical particles called tachyons, that have been explored in the realm of theoretical physics. Still, their existence and practicality remain speculative and have not been observed or confirmed in experiments.
