Your life would be much easier if you simply admitted that you were wrong. If you have an arguement then present it. No decent scientist keeps repeating the same "There's no such thing ... there's no such thing ... there's no such thing.." I've provided you with proof. Perhaps you simply don't have the skills or the training to undersand it. If so then don't attempt to correct those who know better.

re - I didn't say that the Reimann tensor couldn't be related to tidal forces. - Reread the purpose of the post.

I said, the Reimann tensor is not "the tidal force tensor".

Proof of the use of  tidal force tensor. as a synonym for Riemann tensor

From Gravitation and Spacetime - Second Edition,  Ohanian,  Ruffini, page 54

================================================

"....according as the Riemann tensor* does or does not vanish."

*Tidal-Force tensor

================================================

re - There is no such thing as "the tidal force tensor".

A mathematical quantity is said to exists when it  has been defined.

It has been defined!!!!

Proof of the existance of the term  tidal force tensor.

From Gravitation and Spacetime - Second Edition,  Ohanian,  Ruffini, page 41

================================================

We will call the quantity

[51]            Rk0l0 = [mc2]-1 Fk,l = c-2 U,kl

the  tidal force tensor. The extra factor mc2 is provided and the extra indices 00 have been introduced for later convinience.  It turns out that the nine quantities Rmnab;

================================================

re - Now stop harrasing me. - I'm not harrassing you, I'm educating you. That is all in your mind. You're being paranoid. This is a physics discussion forum, remember? Plan on learning new things.

re - Go away. - No.

zc - Stop flaming and spamming or simply go away.
