"She has also connected Planck-scale physics with physics at scales that are easier to study" - Hm, I hoped she would list a lot of phenomenons that are recognizable all the way down.
If everything are emergent fractals from a core equation, then all fractals will be variations of the first (+neighbor fractals) and contain the same-ish mechanisms/phenomenons - just 'mixed' with prior fractals. In most fractal equations we get a pattern that repeat it-self over scales, and for instance the mandelbrot 'bulb' pops up at different scales, and certain shapes re-surface, so I would expect the same type of fractal patterns in the universe where phenomenons show a steady or 'punctuated' path all the way down. They are a little hard to see though - likely because of noise and compounded complex systems that contain many phenomenons at once.
Ignoring std consensus for a sec: I see 'charge'/polarization all the way down, 'pull' forces like gravity/magnetism might be the same core equation and the same for all the other high-level phenomenons. Energy pr. volume space goes up when going down, phenomenons get 'sharper'/more defined and simpler. All point - lightly - towards a fractal universe.
Maybe the proto-equation of the universe looks like x=x² + y (y=noise). Not far from E=mc² + noise.
