In 1967, Gerald Feinberg, a physicist at Columbia University, proposed the existence of these faster-than-light particles. "Since one of the guiding principles of relativity is that all physical laws are the same to all observers, this violation of causality would be a big problem."Īnother oddity: tachyons. "Some observers would see the bullet hit the target before they saw the shooter fire the gun," he said. Schneider uses an example of hitting a target with a gun that shoots bullets faster than the speed of light. Time travel, for one thing, and a breakdown in cause and effect. "Theoretically, strange things happen when you exceed the speed of light," Schneider added. We have accelerated sub-atomic particles to well over 99 per cent of the speed of light, but not equal to or exceeding the speed of light. "There is no experiment that has contradicted special relativity. One hundred years of testing have only reinforced what Einstein wrote, said Donald Schneider, professor of astronomy and astrophysics at Penn State. By the time an object reached the speed of light, Einstein calculated, its mass would be infinite, and so would the amount of energy required to increase its speed. The more mass, the more energy is required. The same theory says that objects gain mass as they speed up, and that speeding up requires energy. ![]() That speed, explained Einstein, is a fundamental constant of nature: It appears the same to all observers anywhere in space. ![]() According to Einstein's theory of special relativity, published in 1905, nothing can exceed the speed of light.
