If, as we currently believe, the speed of light is constant and nothing can travel faster than photons, how did these heat-carrying particles have enough time to reach all the corners of the universe?
Although each single electron is not able to travel at the speed of light, a great number of slow electrons are able to produce a current as fast as an electromagnetic wave travelling at the speed of light in the conductor.
At the moment we have no way of even getting close to a 10th of the speed of light," he added.
The media across the globe went to town with the news in September last year that scientists at an underground laboratory in Switzerland, who have been looking for the elusive God Particle, had instead found a neutrino beating the speed of light by one billionth of a second.
Last year, a team of scientists in Italy made a rather startling discovery about the speed of light while working with tiny particles called neutrinos.
The speed of light is supposed to be the speed limit of the Universe but the latest tests open up the possibility of being able to send information back in time.
Scientists around the world were shocked in late September when results from Italy's OPERA (Oscillation Project with Emulsion-tRacking Apparatus) reported that subatomic particles called neutrinos sent there through the earth from CERN in Switzerland arrived faster than the speed of light in a vacuum.
Ten days ago, a group of European physicists with OPERA, the Oscillation Project with Emulsion Tracking Apparatus, made a shocking announcement: They had tracked neutrinos that appeared to exceed the speed of light.

As a star collapses and explodes at the end of its life, it spits out jets of material that can move almost as fast as the speed of light.
Heating the waveguide locally with a small electrical current alters the refractive index, allowing the speed of light to be quickly tuned over a large range with very low applied electric power.
Thus, if an astronaut traveled in a spaceship moving at the speed of light (186,000 miles per second), his trip to the stars and back would be measured on Earth in years, decades, or centuries, but the astronaut himself would not have aged much at all.
