Amrit,
Yes, the plank scale is where things get "interesting". And this is the area where physicists become very defensive. I'm thinking of Einstein and Heisenberg and just about everyone that followed.
Vlatko Vedral in his FQXi blog summed it up with the statement: All physicists are realists deep down.
I interpret this as meaning everyone assumes the continuity of "stuff" (particles and matter and energy). Quantum mechanics makes this view hard to support. And yet we make "nutty" theories like multiple worlds so that we can have continuity of stuff.
I read your attachment and find I am in agreement with a lot of it, particularly you conclusion that gravity is an entanglement phenomena.
I would say that on the Planck scale everything is a clock (a mass that appears and disappears following the rules of quantum mechanics) and that this clock contains the primordial space and time for the object.
Thanks for you input.
Don L.
