Thanks! That clears it up for me.
Now back to the speed of light. Are you saying that the speed of light is same in SP and GR but the velocity can differ?
That's very interesting. The only experimental evidence available is the local measurement of light speed. We can't meausure light speed in curved space. is that right?
that's fine, but it is determinstic insofar as an Event necessarily determines a result that must fall within a specifed range - if you replay the experiment, the result will always fall within the range. It's sort of a restricted casually determined relation
i'm a little confused. are we talking about the same thing?
i think i mistyped.
my question was really: why are people so sure that causes don't exist for apparently random behavior?
is that the question you were answering?
Certainly QM is deterministic in so far as an event determines a range of values that must fall within definite bounds.
But even a purely determistic theory can have probable outcomes which would be the case where we didn't know enough about the system to predict with accuracy. In the...
