  The high energy proton beams expected when the Large Hadron Collider (LHC)
comes online should provide a pass/fail test for a gravity-related explanation
of ultrahigh energy cosmic rays. The model predicts that particles have two
kinds energies, equal for null gravitational potentials and, in the potential
at the Earth, differing significantly above one TeV. If correct, a 7 TeV
trajectory energy proton at the LHC would deliver a 23.5 TeV particle state
energy in a collision.
