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:
“When words fail us or, quite the opposite, when they rush from our mouths faster than we would like, we can console ourselves that if no single moment is going to define our relationship with a child, neither can a single lapse of good judgment or patience destroy it.”
—Cathy Rindner Tempelsman (20th century)
“Love’s heralds should be thoughts,
Which ten times faster glides than the sun’s beams,
Driving back shadows over low’ring hills.”
—William Shakespeare (1564–1616)
“O thou immortal light and heat!
Whose hand so shines through all this frame,
That by the beauty of the seat,
We plainly see who made the same.
Seeing thy seed abides in me,
Dwell thou in it, and I in thee.”
—Henry Vaughan (1622–1695)
