Oh yeah it appears in Wiki therefore it must be true. Doubly true because not only are there words but there's a picture of a spray of massive particles to look at. I don't know what's wrong with you wiki-heads feeling the compulsion to constantly go off topic chasing squirrels. The topic here is what is relative velocity. Now, Victor, you correctly said c+c is a CLOSING SPEED. Please inform GAHD that closing speed is not a relative velocity and that the max relative velocity is limited to c not 2c. Can you do that for me please. Since he can't google the words closing speed and since you like calling up useless wiki articles, could you post one on closing speed for GAHD to take a gander.
PS. I once sent money supporting Wiki but never again. It's a serious threat to world intelligence.
