Perhaps the fundamental description of the universe does not include the concepts of “mass” and “length,” implying that at its core, nature lacks a sense of scale. 'Supersymmetry posits the existence of a missing twin particle for every particle found in nature.' But there's 'one big problem with supersymmetry: in the particle physics that is observed in today's accelerators, every boson most definitely does NOT have a matching fermion with the same mass and charge. So if supersymmetry is a symmetry of Nature, it must somehow be broken.'
'Scale symmetry[warning: slow-loading pdf], constitutes a radical departure from long-standing assumptions about how elementary particles acquire their properties. 'With their field stuck at a nasty impasse,' 'researchers have returned to the master equations that describe the known particles and their interactions, and are asking: What happens when you erase the terms in the equations having to do with mass and length?'...MORE
