Since "Space" is just a Distance between 2 objects , isn't "Space" just equal to Distance ? If so , then the term "SpaceTime" can be called DistanceTime . Which I think clarifies what is meant . And I think it's meaning is thus a Distance Time . In other words , it just refers to the TIME it...

By "sooner" , in my context , I mean its clock can show less ticks elapsed than the clock on the other object , even though the other object may be travelling at a faster speed .

I think the simple explanation is >>>>>>>>>>>>> You said , " If two particles or objects (represented mathematically by worldlines) start out at the same event (same location at the same time), and take different paths through space-time to meet again at another event, when they meet up...

Maybe I'm not being clear enough . Let's see if we can simplify it . I'm at rest Relative to a Source object . The object shoots a bullet directly towards Me . I measure the speed of the bullet from one position in its path at a certain Time , and its position at a later Time , all Relative...

So , throw all Clocks out the window into the " hyper plane of simultaneity" ???

If you are at rest Relative to the source that fires a bullet directly towards you , and it attains a constant speed of 600 mph towards you while you remain at rest . If you then move directly towards the bullet , does the bullet itself then gain speed relative to its source ? I think not ...

Well , all Measurements are done in an instant of Time . So everything is virtually "at rest" / "frozen in time" at the moment of measurement .

Well of course , everything is in relation / Relative to the Observer .

What ??? So how can you measure anything if you can't determine where an object is ???

Can't you measure an objects location in space at one Time , to its next location after x amount of time ?? So you're measuring it Relative to its original location , and basically irrelevant to your location or motion after x amount of time . As you say , bullet relative speed is very slow...

Well , all speed is relative to some point in space/time . An object moving from point A in space to point B in space , would have a "speed through space" .

That's what I mean by "making sense" though . As you say , Physics can explain or describe something which "matches" observation . If it matches observation , then I would say it "makes sense" . Why would the bullet have to move at speed c , before all observers , regardless of their speed...

I guess my point is , ANYTHING moving through space at some distinct speed , has that speed . And any moving or stationary observer does not affect or change that speed . Relative Measurements of the speed can produce different "Relative speeds" . But those are only "Relative Measurements...

Yes I agree that light has a certain speed . A bullet flying through space at some constant speed , also has a certain speed . Any observer , moving or not , does not affect the speed of either light or the bullet .

Well , the bullet or the light doesn't change their speed , whether I'm moving or not .
