Oh dear, what is it this time.

So we have a 'divide by zero' case.

Good grief. People with ZERO understanding of mathematics try to
critique Einstein's paper. Brilliant.
One HUGE difference between a genuine expert and an ignoramus is that
the expert always *knows EXACTLY the boundaries of his knowledge*.
An ignoramus OTOH always assumes he knows everything and everyone else
is stupid.
