    Falling observer has finite time? Can u clear this doubt?

    Was that last question asked by Maldacena?

    The original word best fitted, (by function), to the detailed content in this discussion, was "Omnipresence of Eternity-now", because the ground state is the least size and change, .ds/.dt aspect in zero-point/adibatic reference frame of spacetime functions assumed for all coordinates. It's an "un-natural" act to differentiate the history of a measured/calculated point of relative position-history by indiscriminate identification, but that is the process of science-math in practice, to rearrange the perceived reality by effective and affective mechanism.
    Recovering the observable, established universal properties, (by converting metaphysics to quantum chemistry), from the mish-mash of social histories, intact, is risky business career-wise.
    Or, is it yet possible to say that gravity is simply an aspect of the solid, liquid and gas or plasma states of entanglement? (In principle, it's the Quantum Chemistry of Superposition)

      +eric taylor don't say that, Plochinski is a very good physicist, and the best Professor , he patiently answer all the questions, and do care about students!

      If you listen at 1.5x, none of that matters
