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 fairies, faster than witches,
Bridges and houses, hedges and ditches;
And charging along like troops in a battle,
All through the meadows the horses and cattle;”
—Robert Louis Stevenson (1850–1894)
“Wooing, wedding, and repenting, is as a Scotch jig, a measure, and a cinquepace; the first suit is hot and hasty, like a Scotch jig, and full as fantastical; the wedding, mannerly-modest, as a measure, full of state and ancientry; and then comes repentance and, with his bad legs, falls into the cinquepace faster and faster, till he sink into his grave.”
—William Shakespeare (1564–1616)
“The light that never was, on sea or land,
The consecration, and the Poet’s dream;”
—William Wordsworth (1770–1850)
