The day I woke up Faster Than Light

I heard this on the radio just when I was about to have a shower. I stared at the mirror, and I was already naked and wet. I wondered if this had to do with this amazing discovery or with the terrible hangover I had this morning.
Are we starting to enter a world full of FTL paradoxes?
The most popular FTL paradox is the grandfather paradox: an astronaut leaves Earth in a spaceship than can travel faster than light (if such thing ever exists, we're not massless photons, you know), and when he returns, he finds that he has travelled back in time, and he is living in a time where his grandparents are yet to give birth to his father (or mother). So he could kill them and enter the realm of FTL paradoxes...

This astonishingly finding was announced yesterday in the Nature magazine by Lijun J. Wang and his team from the NEC Research Institute at Pricenton (New Jersey). Wang warns that Einstein's special relativity theory and the principle of causality aren't being infringed:

"you can make light pulses travel faster than c. This is a special property of light, which is different from a known object like a brick, as light is a wave without mass".

There's an explanation, but it's kinda complicated. Everyone knows that light travels as both a wave and a particle, right? The wave part allows for funky things to happen.

When two waves overlap they create an interference pattern. To help visualize an interference pattern, take two similar hair combs and overlap them (really, this will help). Note the dark and light bands caused by tines and spaces overlaping; these bands are an interference pattern. Now move one horizontally with respect to the other and watch the bands of light and dark move. You should observe that these bands move faster then either comb.

The combs have mass, and thus cannot move at speeds greater then that of light is a vacuum. The bands, however, do not. By moving the combs fast enough you could make the pattern move faster then c. You'd have hard time using them to carry a message from one end of the comb to the other, however.

Because photons travel as a wave, they have crests and troughs (much like the combs have tines and spaces between the tines), so they too create an interference pattern. This pattern (called a wave group) can also move at a different speed (called the group speed then the photons composing the light.

It is this pattern, rather then the photons themselves, that scientists have made move at speeds far greater then that of light. Certainly an impressive feat, but does not violate the known laws of physics.
