exactly Bill. spot on. I used the flip book to describe it to someone yesterday. when you're flipping the pages it appears to have motion but while still there is nothing. I think this might be the illusion spoken of by Buddha in the Dhamapadda and Adi Shankaracharya in his Vivekachudamani reference. I actually like your film analogy better because the "roll it up" makes sense. My analogy only gets to that by talking about linear time not being binding past the 3rd dimension - yours is easier to grasp for illustration. This is similar to motor action field strength calculations done in calculus because they are only an issue at all when there is relative motion between a magnetic field and a current carrying conductor. Absent that differential a field doesn't exist. So the calculation is delta this and delta that blah blah blah. I need some math skills. This is the same theory some are projecting for the hard gravity problem in quantum states. In classical physics we use newton to solve it ... but when you add in time it doesn't even exist. That was Einstein's relativity discovery. namaste.
