Summations Only

Hi there So Goku - good to see you back again.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).

Thanks :-)Might have a look at trying to learn the maths when I retire :-)

Thanks again - just found it on line to read through. Looks like I’ll need to roll up my mental sleeves :-)
