Faster Than Light
It is possible for spin zero particles to travel faster than the speed of light when tunnelling. This apparently violates the principle of causality (physics), since there will be a frame of reference in which it arrives before it has left. However, careful analysis of the transmission of the wave packet shows that there is actually no violation of relativity theory. In 1998, P.E. Low reviewed briefly the phenomenon of zero time tunneling. More recently experimental tunneling time data of phonons, photons, and electrons are published by G. Nimtz.

Famous quotes containing the words faster than, faster and/or light:
“Faster than springtime showers comes thought on thought.”
—William Shakespeare (1564–1616)
“General statements omit what we really want to know. Example: “Some horses run faster than others.””
—Mason Cooley (b. 1927)
“The eastern light our spires touch at morning,
The light that slants upon our western doors at evening,
The twilight over stagnant pools at batflight,
Moon light and star light, owl and moth light,
Glow-worm glowlight on a grassblade.
O Light Invisible, we worship Thee!”
—T.S. (Thomas Stearns)
