physics

Symmetry is fundamental to physics. The Standard Model of particle physics is based on the concept of symmetry: the behaviour of particles is a direct consequence of the symmetries they posess (or lack, depending on which way you look at it). General Relativity is founded on notions of symmetry. As proved by Emmy Noether, all conservation laws - the conservation of energy, the conservation of momentum, and the conservation of angular momentum, to name a few - are the expression of underlying symmetries.

What we need to explain about space

Any theory of gravity would need to account for the following observations:

The primary phenomena we are concerned with in the domain of physics are very basic: space, particles, non-locality, gravity,  motion and the fact that symmetry is a good signpost for understanding the universe. For each of these phenomena, QO has an explanation that differs substantially from that of mainstream science.

QO turns mainstream physics upside down. It provides new and simple explanations for the genesis of the universe, the reason why symmetry is a good signpost towards understanding the universe, the behaviour of spacetime as described by General Relativity, and the arrow of time. It demonstrates why we can do without the concepts of dark matter and dark energy in order to account for the motions and structures of galaxies.
