there is no scientific evidence or established method to determine if a person has traveled through time from another dimension into our world. The concept of time travel and interdimensional travel remains speculative and largely confined to the realm of science fiction.
In the scientific community, the exploration of other dimensions, such as the possibility of additional spatial dimensions beyond the three we experience, is primarily studied in the context of theoretical physics, such as string theory or brane cosmology. These theories propose the existence of extra dimensions but are still speculative and lack empirical confirmation.
While it's interesting to consider the idea of people traveling through time from other dimensions, it falls outside the scope of current scientific understanding. Detecting or confirming such an occurrence would require concrete evidence and scientific investigation that goes beyond the existing knowledge and capabilities in the field.
It's worth noting that claims of time travelers or individuals from other dimensions visiting our world typically fall into the realm of anecdotal accounts, personal experiences, or works of fiction. As of now, there is no scientifically validated method to determine the authenticity of such claims.
