Dark matter – It's all about gravity

I wrote about dark matter research and what it could be. What I have not talked about is the concept behind our need to understand it … the links between matter (mass), gravity and energy. Scientists are aware that they have not quite connected the points yet.

All the materials we know (except perhaps photons) have mass and mass is associated with gravity. Gravity is currently described as a distortion (curvature) of space-time around the mass. All we really know is that this association exists and that, according to general relativity, it is considered a phenomenon and not a force. If it was a force, there should be a field / particle that makes it easier. Until now, no particle or field has been identified. Hmm, it looks like dark matter for me.
