Shalom All:Scientists Mess with the Speed of Light

Using a technique called Stimulated Brillouin Scattering, the researchers were able to slow down or ratchet up the speed of light like the gas pedal on a car. They succeeded in reducing the speed of light by almost a factor of 4 (although that's still plenty fast at 46,500 miles per second), but even more dramatically, the team was also able to speed up the speed of light.By tweaking the relationship between phase velocities, it's possible to adjust the group velocity and create the illusion that parts of the pulse are traveling faster than the speed of light.
---end clip---And what else of "science" is really an illusion?
