Beautiful pictures of the Large Hadron Collider, the worlds largest and highest energy particle accelerator, which is about to start operation outside of Geneva Switzerland. The internet is full of theories about how the LHC is going to destroy the world, but it doesn't seem like any respected scientists are worried about that. But two well known physicists are speculating about something less troubling, but quite possibly much more weird: The authors of this paper claim to show that other terms can be added to the quantum mechanical action that are consistent with current theory and experiment. However, some of these possible terms include conditions in the future that need to be taken into account and summed over. That is to say, what happens in the future could (according to this paper) affect what happens in the present. |
