New Results in Quantum Tunneling vs. The Speed of Light

New efforts in quantum tunneling - both theory and experiment - show that superluminal motion may be possible, while still managing to avoid the paradox of superluminal signaling. Paradoxically, the most promising prospect for moving matter around faster than light may be to put a metaphorical brick wall in its way.
