This is true. I'm not so much trying to understand how our particular 4-d space-time works but how n-dimensional space-times might work, especially 1, 2 & 3 dimensional space-times. Higher dimensional spate-times aren't really that much more difficult to work with but are much harder to...

Minkowski diagrams are good for plotting space-time displacements and showing the space-time 'history' of a particle. But relativistic effects occur due only to the rate of change of those displacements i.e. the velocities, and not the displacements themselves, so no, I wasn't trying to produce...

Thanks for the responses. I thought it would be apparent from the question that I was familiar with the 'linguini' model and I used to think in those terms until I started looking more deeply into relativistic time-dilation, where the sum of two rate of change of displacement vectors i.e. the...

Umm.. You Should Go Out On The Ale More Often?

I'm still working on it too.

While we regard spatial displacement and spatial length as distinct from each other we don't seem to treat time in the same way. Instead, when anything refers to temporal length it seems to actually be referring to temporal displacement. For example, a 5 metre long automobile may travel 100 km...

When I was about six or seven years old I found that, with my young, sharp eyesight, I could just perceive the movement of the tip of the minute hand against the wood-grain of the clock-face as it slowly crept around the face of the family living room clock. Although I knew the clock was...
