An international team of physicists has proposed that tachyons, hypothetical particles that travel faster than light, could be compatible with Einstein's special theory of relativity. Their research suggests that incorporating both the initial and final states of a system into calculations resolves previous theoretical challenges, potentially allowing tachyons to exist and offering new insights into quantum theory and the formation of matter.
Physicists propose that the universe may be filled with particles called tachyons, capable of traveling faster than light, which could potentially make up dark matter and explain the universe's ongoing expansion. This hypothesis challenges the current cosmological model and raises fundamental questions about causality. While the evidence is limited and the existence of tachyons remains unproven, the idea offers intriguing possibilities for further research into the nature of dark matter and the fundamental phenomena governing the cosmos.
A new paper suggests that the universe may be dominated by tachyons, hypothetical particles that move faster than light, potentially explaining dark matter and dark energy. The physicists propose that an expanding universe filled with tachyons can initially slow down in its expansion before reaccelerating, aligning with observations of Type Ia supernovae. While the tachyon cosmological model is unorthodox and unlikely to pass rigorous experimental tests, exploring new and unorthodox directions in cosmology is important as it may lead to breakthroughs in understanding dark matter and dark energy.
