I am the Doctor (Nintendo Remix by Steve.xR1P) - FINAL VERSION by stevexr1p. Time Travel More Complicated Than Previously Thought. In a blow to science fiction writers and daydreamers all over, it appears that the hopes of building a time machine may be dashed once and for all, reports the Los Angeles Times (LA Times) and other media outlets.
Physicists at the Hong Kong University of Technology and Science have just proved that no machine will ever allow a person to travel through time because time travel is flat-out impossible and beyond the limits of the physical laws of the universe. Until now, it was thought that even though light is the ultimate speed limit of the universe, experiments in recent years suggested that single photons might be able to pass that limit. If they could, theory allows for the prospect of time travel. However, a paper in Physical Review Letters shows that individual photons too are limited to the vacuum speed limit.
