Space is relative, it contracts at high speeds. Mass is relative: fast moving objects have a larger inertia. Rest-mass (m0): matter has rest mass and always moves slower than c radiation has no rest mass and always moves at c. E = mc2: energy has mass (inertia) and mass has energy (can do work) There are no things, only processes; no objects, only fields. General relativity: accelerated observers (relationship between acceleration and gravity) Newtonian physics breaks down when particles are very small, very large, very fast, or the. The birth of the universe: the big bang gravitational field is very large. Due to the uncertainty principle, you cannot have things moving if they are very, very small (the forbidden ranges) If a person is standing and has gravitational force acting on them, there is also a normal force acting on them.
