In the article here a theory is discussed that particles, including specifically a hypothetical type of neutrino, could travel through time, as well as through space. The article mentions that the Large Hadron Collider could begin detecting such particles before they are created in subsequent experimental events.
Very interesting, but my question is: Why would one expect a neutrino generated by an event in the future, in the Large Hadron Collider at it’s location in the future, to be detectable in the current location of the Large Hadron Collider? Even if current motion is conserved across temporal travel by some bizarre characteristic of spacetime, we know for a certain fact that the current LHC has a rapidly changing motion due to dozens of forces acting on it in the current frame of reference.
So, it seems to me that the LHC is the one place you could be fairly certain would not show the creation of particles created by the LHC. Is the proposed temporal displacement some quantum quantity, Like one planck interval? In that case, I suppose it might be indetectably altered in its location and vector. Indetectable seems to have drawbacks as well.
I hate time travel stories.
