According to our current understanding of physics based on the theory of relativity, it is not possible for humans or any other object with mass to travel faster than the speed of light in a vacuum, which is approximately 299,792,458 meters per second (or about 186,282 miles per second).

As an object with mass accelerates towards the speed of light, its relativistic mass increases, and the amount of energy required to accelerate it further also increases. At the speed of light, the relativistic mass would become infinite, requiring an infinite amount of energy to continue accelerating. This phenomenon is known as mass dilation.

Moreover, according to the theory of relativity, as an object approaches the speed of light, time dilation occurs. Time slows down for the object relative to an observer at rest. This means that if an object were somehow able to travel at the speed of light, time would effectively stop for it.

Additionally, other effects such as length contraction and the breakdown of causality, as we understand it, would come into play. Length contraction means that an object moving at relativistic speeds appears shorter in the direction of its motion to an observer at rest. Causality refers to cause and effect relationships between events. The theory of relativity suggests that faster-than-light travel would allow for violations of causality, leading to paradoxes.

While there are speculative concepts such as wormholes and the Alcubierre drive that have been proposed in science fiction and some theoretical physics, these ideas rely on hypothetical and currently unproven phenomena such as negative energy or exotic matter. As of now, we do not have any confirmed means to travel faster than the speed of light, and the known laws of physics present significant barriers to achieving such speeds.
