“Quantum physics is actually all about algebra.”Physicists have already managed to unite quantum theory with Einstein’s other big theory: special relativity (explaining how speed affects mass, time and space). If it could, it would indicate that quantum theory might ultimately be more fundamental than general relativity, accounting for four out of five forces – suggesting general relativity ultimately may need to be modified. So it’s not really a theory of everything if it’s not accounting for most of the matter energy content in the universe,” she argues. Another is loop quantum gravity, which suggests Einstein’s space-time arises from quantum effects. “One of the strengths that people will point to with string theory is that string theory built on quantum field theory,” explains Prescod-Weinstein.
