"Physicists Propose Existence of Superluminal Matter in the Universe"
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.
