According to our current understanding of physics, nothing can travel faster than the speed of light in a vacuum. The speed of light in a vacuum, denoted by the symbol "c," is approximately 299,792,458 meters per second (or about 186,282 miles per second).
This limitation on the speed of light is a fundamental principle in Einstein's theory of relativity, which has been extensively tested and confirmed by numerous experiments and observations. According to this theory, as an object with mass accelerates, its energy and momentum increase, approaching infinity as the object's speed approaches the speed of light. Therefore, it would require an infinite amount of energy to accelerate an object with mass to reach or exceed the speed of light, which is considered impossible.
It's worth noting that there are certain phenomena, such as the expansion of the universe, where the space between objects can appear to be expanding faster than the speed of light. However, this is a result of the expansion of space itself and not the motion of objects within space.
To date, there is no experimental evidence or scientific consensus supporting the existence of anything that can travel faster than the speed of light. The speed of light serves as an important cosmic speed limit in our current understanding of the universe.
