As to the 4-D geodesics ... I have read all your posts on this theory. I am a bit ambivalent about it at the moment. I am trying to find a flaw in it. Its tantalising. In short, you base your belief in this on the fact that it is undetectable. A closed system cannot be measured from the inside. Is my interpretation correct?
My initial opening 'attack' on this idea is that a closed system is detectable from the inside if it is continually expanding, including its mass. Because its mass increases continually its opposition (in time .. 4D) to acceleration will change between any two measured points in the systems expansion.
But I am unsure of my own ideas which are a bit hazy around this at the moment and I need more time. Perhaps that polymath of a moderator, not being a science novice like me, will read this and give me a few pointers on how to dissemble your 4-D geodesics. (no offence Dave)
