Whilst I’ve got you on this thread, can I ask a quick question about our velocity through space time. Is my recollection correct, that we (and I guess I should include every particle in that term) are moving though space time at a uniform velocity equal to the spatial velocity of the speed of light. And that that velocity is equal to the sum of our spatial and temporal velocities ? (This being a way, for me, as someone who has no chance of doing the maths, without some serious study to catch me up, to get to grips with how time dilation works, for people (or particles) experiencing different relative spatial velocities).
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
