Do you think our understanding of gravitation is good enough that we can make bold proclamations about nature such as darkmatter, the Big Bang etc?

I ask this question because as demonstrated in my paper here, we can define four more components of the gravitational field and this have the potential to explain the Rotation Curves of Spiral...
