If the Universe is everything, then how can it expand?
The Universe is in flux in a Magnetic pattern and nothing more.
If you go far enough to the edge of the universe you will move through the magnetic field from one pole to the other and end up on the other side. No wormhole no warped space, just physics.
Not magnetism but perhaps black matter behaves the same way. On a grander scale.
Creating the inertia for all Universe movement and orbits. The planets are on a cosmic mag-lift.
