@Deepak. True, but then I think about blindfold chess. With practice, people can run in their mind's eye a little simulated world with its own peculiar rules of time and space.

@dmckee - That's won't be a problem: the maths is unexpectedly benign.

This answer is somewhat over my head at the moment. But it is appreciated, and I will be sure to come back to it when I am more enlightened.

Fix inaccuracy - was assuming spacelike interval

comment How do I develop an intuitive model of spacetime?
Well, I have looked now, thank you. Indeed, a couple of 'aha!' moments so far have been finding out about events separated by a spacelike interval appearing simultaneous for at least one frame, and events separated by a timelike interval, which never appear out of order for any frame. For a while it looked like some kind of structure was emerging, but I have never been able to arrange these local insights into a coherent picture of the whole.
