Mollyann Wingerter In classical physics a bit is information. In quantum physics information is a qubit. In a quantum computer, a quantum logic gate processes both up and down or zero and one bits at a time. This leads to increase in processiing power provided it does not effect the system. In a qubit all directions are possible because it is a particle that is behind it therefore it has the ability to exist as a superposition of different states.

Michael McNeil Geometrodynamics is simply another name for general relativity. See, e.g., Misner, Thorne, and Wheeler's massive tome Gravitation from the 70's, where the two terms are used interchangeably.

Leonardo Varesi and other attempts to unify the gravitation with Maxwell field as a 5dimensional KaluzaKlein, a unified field theory of Einstein........

Jack Sarfatti Wheeler's GMD is based on GR of course, but goes beyond Einstein's 1916 version as Ulla correctly descirbes above. Of course Wheeler was with Einstein at Princeton and Einstein knew what Wheeler was doing.

Jack Sarfatti Yes, GMD was a failed program as Ulla says, though parts of it may rise again, but of course, with quantum theory in Bohm's ontological interpretation and Abdus Salam's strong shortrange Yukawa fgravity that has reappeared in the extraspace dimensions of string theory.
Maybe he used the wrong concept for the unification? Why are forces qubits? Behind a force is a particle!
