I read in article done by prof. Tom Weiler and Chui Man Ho that suggest the possiblity to use the LHC in CERN as a time machine. The concept is using the LHC to send messages back in time with use of LHC and particle that migth exist, called singlet bosson. That said, both emphasizes that this could be a long shot. But my questions is: Could it be done? Is it even possible to do it? I have heard of Dirac's phone. That makes it possible call back in time. But I never seen reseach who acctually tried that. I know it sounds weird and it is on the edge of all known physics. But I see on treads before that some of the issues concerning this topic has been discussed before but not accutally this one.
