Based on our current understanding of physics, it is not possible for any object, including human beings, to travel faster than the speed of light in any medium, whether it be on Earth or in space. The speed of light in a vacuum, denoted as "c," is considered to be the ultimate speed limit of the universe according to Einstein's theory of special relativity.
As an object with mass approaches the speed of light, its energy requirements to continue accelerating increase infinitely, and its relativistic mass also increases. This makes it impossible to reach or exceed the speed of light without violating the known laws of physics. Consequently, it is not feasible for a human being or any physical object to achieve superluminal (faster-than-light) travel on Earth or anywhere else.
While science fiction often explores imaginative concepts like faster-than-light travel, it is important to distinguish between scientific speculation and the limitations imposed by our current understanding of the laws of physics. As of now, traveling faster than light remains firmly in the realm of speculation and fiction.
