Mass - Energy
What is mass? Let's start knowing that energy in General Relativity bends space-time, and the bent space affect objects with mass. Question. If the photon has not mass, why does it gets affected too by huge bending of space-time? Because as stated here space-time affects all energy. So yes gravity affects energy. And if a particle like photons are energy, their motion gets affected. Because mass = energy. Mass energy moving gets the shortest path in the bent space-time. This is so, because equations of General Relativity say so. And this shortest path, is the shortest path of equations that they use to visualise reality. What is behind this space-time? Why does it curve? Why the curvature affects all energetic moving objects, which in essence are all particles? Because we must understand what is behind everything. Higgs is space-time. The amount of Higgs per absolute infinite 3 dimensions normal Euclidean space - density. Now. All particles travel at infinite speed. ...
