Okay. So, |x2'-x1'| != |x2-x1|, even for very, very small v.
Does |t2'-t1'| ~= |t2-t1|, for very, very small v?
What is the magnitude of the four-vector? Is it (x2'-x1')^2 -
c^2(t2'-t1')^2 for F' and (x2-x1)^2 - c^2(t2-t1)^2 for F?
Is the magnitude invariant?
I know these questions are pretty naive and, perhaps, a tangent
to the thread, but I've been reading this thread for a while
and I'd like to be able to follow it.
