Quantum Gravity and String Theory


Eight Assumptions of Modern Physics Which Are Not Fundamental

Authors: Juan Ramón González Álvarez

This essay considers eight basic physical assumptions which are not fundamental: (i) spacetime as the arena for physics, (ii) unitarity of the dynamics, (iii) microscopic time-reversibility, (iv) the need for black hole thermodynamics, (v) state vectors as the general description of quantum states, (vi) general relativity as a field theory, (vii) dark matter as real matter, (viii) and cosmological homogeneity. This selection ranges from micro-physics to cosmology, but is not exhaustive.
