Hi jack,
"In other words the spacetime separation need not be spacelike. It can be timelike."
What is your idea about what time is? Is it a measure of object activity that can be reversed. Or, is it a unique fundamental property that exists independently of object activity? If so, what empirical evidence do you know of that shows that unique fundamental, independent of object activity, time suffers effects? Is there a controlled specimen of this unique fundamental time held in a laboratory that you know of? Which kind of time is involved in your view of 'timelike'? In case there is any uncertainty about what I mean by 'unique fundamental time', it is not a measure of object activity. The unit of second does not measure it. The unit of second is a measure of object activity. It is defined as such. My reason for asking this question is that I find physicists' claims that a measure of object activity is the property of time, empirically unsupportable. The empirical evidence for object activity contains an indefinable property of time as part of its basis. What time is your time?
