[I just happened to see this.]

This is just plain wrong. The Schwarzschild manifold has Ricci=0 everywhere, and

Riemann!=0 everywhere. Indeed EVERY vacuum region of EVERY manifold of GR has

Ricci=0, and most of them have Riemann!=0 (only a handful are flat).

It's remarkable how much effort Koobee Wublee expends while trying to pose as

knowledgeable; he actually knows almost nothing about GR and its mathematics.

Essentially everything he says is wrong, with the exceptions being

indistinguishable from occasional lucky guesses.

That's why I rarely respond to his nonsense. He has repeatedly

proven he is incapable of learning....
