the claim that something moving faster than light perceives spacetime as having three dimensions of time and one dimension of space is not supported by mainstream physics.
According to our current understanding of physics, as described by Einstein's theory of special relativity, the speed of light in a vacuum is an absolute speed limit. It is commonly referred to as "c" and is approximately 299,792,458 meters per second. Special relativity establishes that nothing with mass can reach or exceed the speed of light. As an object with mass approaches the speed of light, its energy and momentum increase, and its time dilation occurs. However, it does not change the fundamental structure of spacetime.
The claim you mentioned seems to contradict the principles of special relativity, which forms the foundation of our understanding of space and time. According to the theory, spacetime consists of three dimensions of space and one dimension of time, and the geometry of spacetime is consistent for all observers, regardless of their relative motion. The concept of perceiving additional time dimensions while moving faster than light is not a widely accepted or supported idea in mainstream physics.
It's important to note that scientific claims should be critically evaluated and subjected to rigorous scrutiny before accepting them as true. Extraordinary claims require robust evidence and confirmation from the scientific community through peer-reviewed research. If there has been a recent study making the claim you mentioned, it would be necessary to review the specific details and evidence presented in that study to evaluate its validity and its implications for our current understanding of physics.
