So we are studying special relativity physics at school right now and I have a question and was hoping you could answer it for me, this is not homework related.

Lets assume that there is only movement along the x axis.

A is positioned at x = 100 (arbitrary)

At t = 0 for A (and B) B is moving towards A from x = 0, with constant velocity 0.999.

Now lorentz tells me that A will observe that B spends lets say 5 seconds to reach him, while B will observe a much shorter time.

1) Now how will these 2 ever meet??

2) Will A say that he met B after 5 seconds and B will say a much shorter time? In that case, who is right? Is the whole point that both of them are right?

3) Their meeting is inevitable so they must meet but a meeting requires time and space to be equal for both, how does this work out?
