There are many theories and facts which seem to be different but really very tightly connected. I am enlisting them here for future reference:
- Light is affected by the geometry of space (gravity).
- Gravity is proportional to the mass of the matter.
- Mass is an unknown property. We are only expecting the Higgs to be found at LHC. But, if I am not going in wrong direction then we will never find Higgs. See: Higgs Boson
- Magnetic Flux
- Electric Flux
