A reader forwards this from a “prize-winning, Ivy League physicist”:

“Actually, the real impossibility is to transmit INFORMATION faster than the speed of light. Super-luminal “collapse of the wavefunction” has been known for a long time, I haven’t read what is in the link, but it sounds like they are really claiming the latter. We’ve known that the idea that “particles can’t travel faster than the speed of light” is based on pre-quantum mechanical ideas of particles.”

Me: I’m not sure what to make of any of this, but it sounds a bit like the EPR paradox which fascinated me in high school.
