Question

Do you think one must posit the existence of two time axes—a view you’ve written about here several times—in order to reject the frozen-time theory, which is the accepted interpretation of the spacetime conception in general relativity? Or perhaps there’s no need to resort to that, and it’s enough to say, as Avshalom Elitzur tries to argue (in various strange models), that “the universe is a four-dimensional spacetime containing events and world-lines, as relativity says, except that this universe expands—not only in its spatial dimensions but also in its time dimension: it ‘grows’ toward the future.” And does this have implications for the possibility of free choice (and perhaps also for the quantum probability function—whose genuinely probabilistic aspect does not fit so well with the description of spacetime in the frozen relativistic view)?
