Most still do not get -- understand -- the two state energy-less "time crystal" state recently modelled by Google. Nothing better demonstrates the beginning state / end state of the time-scape better than this binary "and/or" state. It is both here and there state, and, here or there state.... both past and future state, and, past or future state. No it is not cyclic ("and" state), and, yes it is cyclic ("or" state). How else an energy-less state than both states at once in the "and", the "or", the "and/or", binary state?
Only the finally realized existence of the "and" state realizes the whole -- all at once a constant of 'binary' state -- to be forever an energy-less state: Universe (one world state (the finite-singular observable universe state... an energy state)) and/or Multiverse (many worlds state (the infinite-multiple unobserved and unobservable universes state.... altogether a reductionist -- overall an energy zeroed out -- state)).
