[FOM] closing thread on speeds exceeding speed of light

[Joe Shipman]

I'm sorry to see this thread closed before anyone mentioned the work of Scott Aaronson, who showed that closed timeline curves allow for the feasible solution of PSPACE-Complete problems, along with many other connections between the foundations of mathematics and the foundations of physics. A good introduction is his paper "NP-complete Problems and Physical Reality", available here:
