This looks like the most natural question regarding ultra-high energy cosmic rays, but it’s also one of the hardest ones to be answered.
The possibility of some level of Lorentz invariance violation at very-high energies has been proposed in the context of theories beyond the Standard Model, quantum gravity and string theory.
