I don't think that's a coherent division. Space is an aspect of spacetime, and motion isn't a 'thing' it's a contextual property of things.To my understand everything is either space, matter, or motion.
As I already said, current understanding is that motion doesn't determine the elapsed time before radioactive decay; once you start redefining your terms to include what appear to be exceptions to your argument, you're in fallacy territory.The isotope is matter, its process of decay is motion. The isotope's motion is consistent allowing for it to be a good standard of motion.
You may believe that, but you don't know, and as best we can tell, it's not the case - that's why QM events are said to be random.We use the isotope's movement to compare to the interval which I believe is a process of motion we can not yet detect. In this respect the isotope is like a clock because it is used to compare motion to its own motion.
Relative motion causes time dilation:Yes, I am not talking about observing time dilation. I am talking about what causes time dilation.
"Time dilation is a difference in the elapsed time measured by two clocks, either due to them having a velocity relative to each other, or by there being a gravitational potential difference between their locations" wikipedia
This is false (assuming you're not referring to air resistance). As I said previously, Lorentz invariance means that the laws pf physics are the same for you, moving uniformly relative to some observer, as they are for that observer. So once you stop accelerating, you will measure the same effort to move your hand as you did while sitting at the lights. But while you are accelerating away from the lights, you'll find it harder to move your hand, due to the acceleration.This is what I was trying to get at. I can explain time dilation without the need of space time distortion.
Imagine you are in the car and are moving fifty miles per hour. Let's say you move your hand to turn the air condition up. The movement of your hand requires a certain amount of energy. The amount of energy required to move your hand is more than if the car was not moving at all.
Nope- you seem to be confusing what you experience and what an observer in relative motion might observe.This gets exaggerated to the point that if somehow you got your car to let's say half the speed of light the energy required to move your hand would be a lot more. Since the motion of your hand only happens with so much energy the motion of your hand has to slow down.
It's a question of how 'absolute' is used in the physics of space & time. In Newtonian physics, space and time are separate, and time is 'absolute', meaning it runs at the same rate everywhere, any moment in time is universal (e.g. a universal 'now'), and events that are simultaneous for one observer are simultaneous for every observer.I apologize, this appears to be incident of the one those "language barrier" things I was talking about in a previous post. The additive nature of movement you and I have been talking about shows that movement isn't diminished in anyway, but simply built upon. I guess it depends on how you define absolute. Here's the definition from google that is most like mine,
"not qualified or diminished in any way; total."
Einstein's special relativity showed that this is not the case in the real world.
No. Both are right - an observer will obviously never see their proper time dilate - how could they? But one observer's clock really does run slow for another observer in relative motion (and vice-versa). That's why it's called relativity. It's not an illusion or a trick of the light, time is not absolute.From an observers point of view we are time dilated from our point of view we are not. Both are true, but who is right? We can't be both be time dilated and not time dilated. That is highly illogical. The answer is simple. We are time dilated its just that since we don't perceive it we do not notice it and therefore it is not a part of our point of view. Another way of saying it is, what we perceive as normal is relative to what level of time dilation we are currently affected by.
