Is dark matter's main rival theory dead?

Nice theory! That would help explain the Great Attractor. The Universe could actually be a deformed blob of spacetime and the Big Bang and its development just happens to be the result of this blob's movements.

There are rogue blackholes, maybe they leave spacetime deformations behind them that could be observed?

I wouldn’t expect to find any “empty” spacetime deformations, since by their very nature they would attract matter. I would however expect more gravity than the presently observable matter could explain.

I wonder if that can explain some of the large scale filament type structures we see.
