Doubly-special relativityDoubly-Special Relativity
is a new theory of special relativity
first postulated in a paper by Giovanni Amelino-Camelia. In this theory, he postulates that in addition to the speed of light
, a characteristic energy scale based on the Planck scale
should remain invariant
under relativistic transformations.
One of the motivations for this work is the observation of high-energy cosmic rays that appear to violate the Greisen-Zatsepin-Kuzmin limit: the so-called GZK paradox.
