Howdy.

I was a sometimes-reader of Overcoming Bias back in the day, and particularly fond of the articles on quantum physics. Philosophically, I'm an Objectivist. I identify a lot of people as Objectivist, however, including a lot of people who would probably find it a misnomer.

I created my account pretty much explicitly because I have some thoughts on theoretical (some might prefer the term "quantum", but for reasons below, this isn't accurate) physics and wanted (at this point, needed might be more accurate) feedback, and haven't had much success yet getting anything, even so much as a "You're too stupid to have this conversation."

So without much further ado...

Light is a waveform distortion in gravity caused by variation in the position of the gravitic source; gravity itself has wavelike properties at the very least (it could be a particle, it could be a wave, both work; in the particle interpretation, light is a wavelike variation in the position of the particles, caused by the wavelike variation in the originating particle's position). Strong atomic forces, weak atomic forces, gravity, and the cosmological constant/Hubble's constant are observable parts of the gravitic wave, which is why the cosmological constant looks a lot more variable than it should (as it varies with distance). A lot of the redshifting we see is not in fact galaxies moving away from us, but a product of that the medium (gravity) that light is traveling in is spreading out (for reasons I'll get into below) as it attenuates. Black holes are not, in fact, infinitely dense, but merely extremely so.

Gravity moves at the speed of light - light is, in effect, a shift in gravity. This is why matter cannot exceed the speed of light - it cannot overcome the infinitely high initial peak of its own gravitic wave. I believe this is also the key to why the wavelength of gravity increases with distance - the gravitic wave is traversing space which has already been warped by gravity. The gravitic wave moves slower where gravity is bending space to increase distance, and faster where gravity is bending space to increase space. This results in light becoming spread out in certain positions in the spectrum, and concentrated in others; a galaxy that appears redshifted to us will appear blueshifted from points both closer and further away on the same line of observation, and redshifted again closer and further away respectively yet still. Most galaxies appear redshifted because this is the most likely/stable configuration. (Blueshifted galaxies would either be too far away to detect with current technology, or close enough that they would be dangerously close. This is made even more complicated by the fact that motion can produce exactly the same effects; a galaxy in the redshift zone could appear blueshifted if it is approaching us with enough velocity, and the converse would also hold true.)

The nomer of quantum mechanics is fundamentally wrong, but accurate nonetheless. Energy does not come in discrete quanta, but appears to because the number of stable configurations of matter is finite; we can only observe energy when it makes changes to the configurations of matter, which results in a new stable configuration, producing an observable stepladder with discrete steps of energy corresponding to each stable state.

I go with a modified version of Everett's model for uncertainty theory. The observer problem is a product of the fact that the -observer's- position is uncertain, not the observed entity. (This posits at least five dimensions.) Our brains are probably quantum computers; we're viewing a slice of the fifth dimension with a nonzero scalar scope, which means particles are not precisely particulate.

Dark matter probably has no special properties; it's just matter such that the substructure prohibits formative bonds with baryonic matter.

Particularly contentiously, there probably are no "real" electrical forces, these are effects produced by the configurations of matter. Antimatter may or may not annihilate matter; I lean towards the explanation that antimatter is simply matter configured such that an interaction with matter renders dark matter. (The resulting massive reorganization is what produces the light which is emitted when the two combine; if they annihilate, that would stop the gravitic wave, which would also be a massive gravitic distortion as far as other matter is concerned. Both explanations work as far as I'm concerned)

(For those curious about the electrical forces comment, I'm reasonably certain electrical forces can be explained as the result of modeling the n-body problem in a gravity-as-a-wave framework, specifically the implications of Xia's work with the five-body configuration. I suspect an approximation of his configuration with a larger number of his particles becomes not merely likely, but guaranteed, given numbers of particles of varying mass - which results in apparent attractive and repulsive forces as the underlying matter is pushed in directions orthogonal to the orbiting masses, an effect which is amplified when the orbits are themselves changing in orthogonal directions. The use of the word "particle" here is arbitrary; the particles are themselves composed of particles. Scale is both isotropic and homogeneous. As above, so below.)

Time is not a special spacial dimension. It's not an illusion, either. Time is just a plain old spacial dimension, no different from any other. The universe is constant, it is our position within it which is changing, a change which is necessitated by our consciousness. The patterns of life are elegant, but no more unusual than the motions of the planets; life, and motion, is just the application of rules about the configuration of contiguous space across large amounts of that space.

This means that the gravitic wave is propagated across time as well as all the other spacial dimensions; we're experiencing gravity from where objects will be in the future, and where they were in the past, but in most cases this behavior cancels out.

The general mile-a-minute solve-all-of-physics style of presentation here is tripping my crackpot sensors like crazy. You might want to pick one of your physics topics and start with just that.

Also, wondering how much you actually know about this stuff. I'm not a physicist, but ended up looking up bits about relativistic spacetime when trying to figure out what on earth Greg Egan is going on about these days. Now this bit,

Time is not a special spacial dimension. It's not an illusion, either. Time is just a plain old spacial dimension, no different from any other.

seems to be just wrong. A big deal with Minkowski spacetime is that the time dimension has a mathematically different behavior from the three space dimensions, even when you treat the whole thing as a timeless 4-dimensional blob. You can't plug in a fourth "spatial dimension, no different from any other", and get the physics we have.

Minkowski spacetime is primarily concerned with causal distance; whether event A can be causally related to event B. Time has a negative sign when you're considering causality, because your primary goal is to see whether any effect from event A could have been involved in event B. Using the Minkowski definition of time, an object A ten million light years away from object B has a negligible spacetime distance from that object ten million years in the future and ten million years in the past from any given point in time.
