This question I see relevant to him:
The LAR and the light speed principle, they are not reconcilable, something has to give. What probability he assigns that the speed limit c has already gave up, last year in Gran Sasso? Especially in the light of current doubts about how good the cable connection was in the measuring equipment.
I don't think he predicts that returns will accelerate literally forever, so I don't see the contradiction.
I realize this is late notice, but I just found out. He goes on at 8pm and will likely be answering questions by 9:30. I would like to ask him some great questions and I will ask as many of the best that I see here as possible. Any ideas?
