In the meantime, further research is needed to determine whether or not particles can break the speed of light. However, there is no consensus on this among physicists, and it will take quite some time before this question can be answered definitively. Some scientists argue that the speed of light is not a constant in all cases. “Whenever you’re in these circumstances, you’ve got to go to the community,” he concludes. “I welcome outsider skepticism,” Ereditato adds, “but the researchers have been unable to uncover any other explanation for our remarkable finding.” “I don’t think it’s time to panic quite yet.” “It’s tough to reconcile with what OPERA is saying,” says Kyle Cranmer, a physicist at New York University. The fact that a separate study of a pulse of neutrinos from a nearby supernova known as 1987a revealed anomalies raises concerns about OPERA’s findings. Many experiments have searched for particles traveling faster than light speed in the past and found nothing. Many scientists, on the other hand, remain doubtful. If you eliminate the speed of light, according to string theory, neutrinos that are faster than light may be slipping through extra dimensions that we cannot see, which would mean that our current understanding of the universe is incomplete.Īntonino Zichichi, a theoretical physicist and emeritus professor at the University of Bologna If MINOS confirms OPERA’s findings, the consequences will be significant. Without concrete proof, they believe that it is best to stick with the current understanding of the universe. They argue that the theory of relativity has been tested and found to be accurate in all cases and that there is no evidence to suggest that it is flawed. Some scientists are not convinced that particles can break the speed of light. The trick would be to find the specific laws in each of these universes that govern particles’ behavior, which might allow them to exceed the speed of light without breaking any physical laws. Scientists believe that there is not just one universe but many parallel universes. Violating this law would mean that the particle could move faster than light without breaking the cosmic speed limit.īut so far, no one has created a particle that breaks this law. The problem is that such a particle would have to violate the law of energy conservation, which states that energy can neither be created nor destroyed. Many scientists believe that particles can exceed the speed of light.Ī recent Nasa study carried out by Marc G Millis, who was formerly in charge of research into ultra-fast propulsion at NASA’s Breakthrough Propulsion Project, claimed that if a particle were to move slightly faster than it should relative to Earth, but slower than the speed of light, it would create a warp field that could travel to other galaxies in minutes. Is It Possible to Travel Faster Than the Speed of Light - The Universal Speed Limit?
It’s as though space and time have been mixed up with each other so that moving objects are squeezed differently from those standing still. He would see everything squashed in his direction of motion, and time slowing down for everyone else. To someone traveling near the speed of light, time would slow down, while to an observer stationary on Earth, the traveler’s time would speed up.Īnd what would the traveler see if he looked back at a stationary observer? In the world of relativity, there is no such thing as absolute velocity. Only massive particles could approach it but never surpass it.Īccording to Einstein, the speed of light was the same for all observers, regardless of their relative velocity.īut what if a particle could break this speed limit? What would happen then? This was Einstein’s unchanging axiom when he developed his theory of relativity: that there existed an ultimate cosmic speed limit, and that only massless particles could ever reach it. Nothing can travel any quicker than the speed of light.
