Is it possible to have (G)ravity independent of the existence of
Matter?

A bit more, if Matter never existed, would there be Gravity?

Weyl tensor. No mass is required for gravitation.

The property that is invariant is self referential. Same chicken and

Gravity sure seems to be dependent on mass if one looks around a bit,
at least out to the causal horizon, that is..

Know something tehnically valid before you speak,

Yes, I agree. Gravity, as explained, is not technically valid.
