I imagine some of you guys won't believe it, but I've nailed it. I've developed a unified model that is in effect the "theory of everything". It's based on relativity, it's totally in line with Einstein, and it explains quantum mechanics in very simple terms. Time travel is out, we don't need extra dimensions, parallel worlds are kicked into the long grass, and it unifies the forces via geometry. The main points are listed below, please PM me if you want a copy of the paper or the draft book.

In barest essence energy is a volume of stressed space.

Mass is a measure of the amount of energy that is not moving with respect to the observer.

Charge is curl, charge is twist. An electric field is an isotropic region of twisted space, and if we move through it we perceive a turning action which we then identify as a magnetic field.

Time exists like heat exists, being an emergent property of motion. It's a cumulative measure of motion used in the relative measure of motion compared to the motion of light, and the only motion is through space. So time has no length, time doesn’t flow and we don’t travel through it.

Gravity is an extended tension gradient opposing matter/energy stress, wherein the speed of light varies resulting in gravitational time dilation and attraction through refraction.

Space is a one-trick pony, and the only trick is distance. The photon is energy, and is a rippling change of distance that makes for more volume. A change of distance is a distance, so space and energy are the same thing.
The photon is a wave of gauge change. We can tie it in knots to make particles with mass and charge. The electron is a trivial knot, the positron is its mirror image. So matter is just space with a twist that’s tied in a knot.

The common photon amplitude is a spatial extension of 3.86 x 10-13 metres, and is the quantum of quantum mechanics. The wave function doesn't describe where a point particle can be found, it describes where the particle is.

The electron is a trivial knot, a turn and a twist. The proton is a trefoil knot, three turns and a twist. The neutron is a proton plus a twist and two turns. The neutrino is a turn, a mere running loop, and muon and tau neutrinos have more loops, as do the muon and tau themselves. The antiparticles are mirror-image knots that go the other way, and the unstable particles are not knots, so they always come undone.

The weak interaction is mere friction, the residual strong force is mere neutron linkage. The electromagnetic force is caused by twisted space, whilst the strong force is the stretch that keeps space together. Gravity is the reaction, and a gradient in the relative strength of the electromagnetic force and the strong force.

The Universe expands because space behaves like a compressed elastic solid, but there is no substance, and there's nothing outside to hold it in. There is no space beyond the universe, there is no distance, there is no there. So the universe is unbounded, but finite and flat. More space expands more, so the expansion is going exponential and gravity is losing its grip. It expands between the galaxies but not within, so space is not homogeneous. It's dark, it's energy, it causes flat galactic rotation curves and gravitational lensing, so we don’t need dark matter.

Black holes are frozen stars, where gravity is so strong because space is so strong that c is zero, so light can’t move, nothing can move, and nothing can fall through the event horizon. It's the end of time, the end of events, and there is no singularity and never will be. There's nothing inside it because there is no inside it, it’s a something and nothing, a bubble a shell, a hole in space, like the universe inside out.
