Description: Tachyon is a hypothetical particle that, according to some physical theories, could travel faster than light. Its existence stems from Einstein’s relativity equations, which suggest that while massive particles cannot reach the speed of light, massless particles could theoretically exceed this speed. Tachyons are characterized by having an imaginary mass, implying that their energy and momentum behave differently from conventional particles. This peculiarity has led to debates about the implications of their existence in modern physics, especially in the context of quantum theory and relativity. Although tachyons have not been observed in experiments, their study has stimulated interest in theoretical physics and inspired various speculations about the nature of time and space. The idea of tachyons has also permeated popular culture, appearing in science fiction works and theories about time travel, reflecting their appeal as a concept that challenges our traditional notions of physics.
