So you contradict yourself. Two waves do not produce a black ring,
they produce two rings (one dark, one bright) ...

Don't know what planet you live on, Richard, but on this one if there
are two rings, one dark and one bright, there exists a dark ring. No
contradiction at all. Please sober up and try to do a better job next
time.
