OK, so you admit time is real but unknown. I guess your "illusion" claim was due to schitzophrenia on your part. = - - - - - - - Jacques Mallah ([EMAIL PROTECTED]) Physicist / Many Worlder / Devil's Advocate "I know what no one else knows" - 'Runaway Train', Soul Asylum My URL: http://hammer.prohosting.com/~mathmind/ __ Do You Yahoo!?

Of course Turing Machines have clocks They perform their operations sequentially and need a "clock signal" to move from one step to the next. The duration between the clock pulses can vary and can be entirely arbitrary, one picosecond or ten milleniums. But they don't have REAL TIME CLOCKS, Jacques You know the kind that tells computers the time of day and the date... And of course they also don't have interrupts! George

This is certainly true, but on the other hand between any two rational numbers there are also an infinite number of irrationals. But even if this were not the case, the fact that any two rationals have other rationals in between would not make Hal's claim of continuity true; rather it would prove the opposite, discontinuity. Seems to me we have here a demonstration that, as in physical reality, continuity cannot exist. What could it possibly mean? -dlj.

It means "nonsense." OK. This is your opinion. First sentence: The comp hypothesis depends on Turing Machines which are inherently discrete. A continuous universe would not by emulable by a Turing Machine. Read Bruno's latest post. He has a much better grasp of this issue then me. Second sentence: To prove that if physical constants are to take any definite value, the universe must be quantized. Let us say that there exist a TOE based on one single physical constant X (for example Planck's constant). Without loss of generality, we can say that the value of X is 1, since there is no other constant to compare it to. Assuming that a Turing machine is used to apply this TOE to solve poblem and calculate any quantity in the world then any quantitiy derived from this TOE would have to belong to the set of integers -- including space time and energy. We can extend this reasonning to TOE's that include n arbitrary physical constants. George Levy
