Quark-faster than the speed of light?

I've heard a bunch of things that scientists supposedly proved that quark is faster than light in speed?
True,false?

I don't think so, wouldn't they have to be mass-less to travel faster than C?

Wouldn't have thought so. Quarks are bound inside atoms and can't exist by themselves, I don't think their speed can be measured as a result.

IIRC, quarks travel just below the speed of light. The only thing I am aware of which can travel faster then light is patterns within a light beam. no physical thing (NRG or Matter) can travel faster then a particle of EM radiation.

 

What's the speed of quantum echoing effects and how do they propagate?

Indeed. What are quantum echoing effects?

 

Are you thinking of tachyons?
