New Scientist(link is external) explores whether there’s a deeper level of the universe beyond Einstein’s theory of relativity, citing research from Professor Shahn Majid in the School of Mathematical Sciences.
Professor Majid suspects that the relationship between curved momentum space and quantum uncertainty “works two ways: the curvature of space-time, a manifestation of gravity in Einstein’s relativity – implies that momentum space is also quantum”.
