Smooth or grainy?

A SISSA paper reviews research on the grain of space-time A paper by Stefano Liberati from SISSA has been selected as one of the 2013 Highlight papers (the best papers of the year) of the journal Classical and Quantum Gravity. The paper is a systematic review of the methods devised by scientists since the 90s to test Einstein’s laws of Special Relativity, up to the highest observable energies. These types of tests are important: deviations from Special Relativity could in fact indicate that space-time is not continuous but grainy.
