The Ultimate VR Device

Light, thin, sturdy, mobile, supercapacitor-charged computer (PC/MAC/Linux/NET/Android/iOS) glasses, that covers both eyes (and ears) completely.

It must be possible to wear it even while lying on the bed, even for many hours everyday, w/o feeling sick or tired.

It could be letting no light from outside to to the either eyes.
Or it could set for any level of transparency wanted, from 0% to %100, together and/or independently, for the eyes.

Sounds coming from outside also must be fully adjustable.

It must have WiFi, Bluetooth, USB (at least two most common type connectors) for minimum.

It has all kinds of sensors for VR and smartphone applications.

It must have a good mouse (it could be something similar to a short and fat pen (USB-chargeable), with a track-point at top, for example).

For software, it must have all kinds of commonly-used remote desktop connection/access software, if possible.
Also it would be better, if it had its own virtual keyboard(s), internet browser, media player, text/document/image/video viewer(s)/editor(s).

It should use (at least one) standard removable solid state memory card, as for its on-board long term file storage drive.

Also it would be better, if it also supported AR.

Baryon Asymmetry Problem

One of the biggest unsolved problems in physics is the Baryon Asymmetry (BA) problem. Why the Big Bang (BB) created more matter than antimatter?

I think the first question for BA really is, what was the mechanism of particle creation? I think the assumption in the world of physics, since the beginning of BB Theory, was Pair Production (PP).
But PP seems to be always creating matter-antimatter particle twins, so always equal amounts of matter and antimatter. Then what was the reason, the balance tipped towards the matter side?

But, is PP, the only possible mechanism of particle creation we know?

When an unstable matter/antimatter nucleus or particle decays, it also creates new particles and/or antiparticles, true? If true then, is not it possible, BB created new particles like an unstable particle decay event? If so then I think the most reasonable assumption would be, the whole universe was a single unstable (elementary) quantum particle at the beginning. (Or multiple particles? (Then most likely, an odd number of particles!))

If our universe began as a single unstable quantum particle suddenly decaying, what set of particles/antiparticles were the decay products then? Since our universe contains much more DM than matter, one of the decay products must be DM particles. I think we need to find out for certain (if possible), how DM/M ratio of our universe changed since the beginning. I think if the ratio was always constant, then it would mean DM and M particles were created with that ratio right in the beginning. And if amount of matter (vs DM), kept increasing since the beginning, then would mean DM was creating matter, since the beginning. (So it would also mean BB only created DM, initially.)

Clearly, each unstable nucleus/particle decay event, is like a very powerful explosion, at its own scale. So our universe beginning as a single unstable quantum particle decaying, would be definitely the mother/father of all explosions, thus truly deserving the name BB!
Which I think would also explain how/why the era of inflation (hyperfast expansion) happened, in the beginning times of our universe.

If our universe started as a single unstable (elementary) quantum particle, the biggest question would be this:
What were its properties? (All possible sets of quantum elementary particle state values for energy, wavelength/frequency, rest mass, spin, charge, color charge etc.)
Obviously the main constraint of the problem, is that the final result of the initial particle decay process, needs to be able to produce all DM/M of our known universe. (And I think that requires us, first considering how quantum properties of particle decay products, relate to quantum properties of the initial unstable particle that decayed.)

I think this maybe implying another constraint for the problem:
From Wikipedia:
"The presence of an electric dipole moment (EDM) in any fundamental particle would violate both parity (P) and time (T) symmetries. As such, an EDM would allow matter and antimatter to decay at different rates leading to a possible matter-antimatter asymmetry as observed today."

A GUT OF QUANTUM GRAVITY

What really is spacetime and what really are elementary quantum particles?

Imagine spacetime is an emergent property which is a gas-like medium, created by virtual quantum particles keep popping in and out of existence for extremely short durations, which is also the medium of quantum vacuum. Imagine what flat spacetime is the volume where probabilities for creation of positive and/or negative energy/mass virtual particles are equal. Imagine positive curvature spacetime is the volume where probabilities for creation of positive energy/mass virtual particles are higher. Imagine negative curvature spacetime is the volume where probabilities for creation of negative energy/mass virtual particles are higher. (Realize then spacetime would be really a medium of probability.) Imagine when a region has excess positive energy available, positive energy/mass virtual particles are not just created more but stay in existence longer.
And whenever/wherever the energy is higher than necessary thresholds, virtual particles created as real particles. (And when a region has excess negative energy available instead, then negative energy/mass virtual/real particles are created similarly instead.)

Imagine when light passes thru spacetime regions with different positive/negative curvature, it is like passing thru gas/fluid regions with positive/negative index of refraction.

(So a positive energy/mass particle/object creates a field of positive spacetime curvature around of itself, which we call its gravitational field.)

Realize if gravitational field is polarization of virtual particles, then creating Casimir Force is actually creating artificial spacetime curvature/gravity!

Imagine all elementary quantum particles of Standard Model, which are used to create virtual particles, which create the gas-like spacetime medium, are really quasiparticles of a fluid-like medium, like bubbles created by a boiling fluid. Imagine that fluid-like medium is created by a Cellular Automaton Quantum Computer (CAQC) with Planck length scale cells of qubit registers. Imagine each elementary quantum particle is a like a cluster of information/probability. Probably like a spherical probability wave, traveling in the fluid-like medium created by the CA, maybe similar to CA used for fluid simulation, like LGCA(FHP)/LBM. (Also realize that what happens in CA used for fluid simulation, about predictability of the future (nature of time), is really similar to what happens in our real physical Universe:
In microscale future is unpredictable (particles move randomly), but it becomes more and more predictable with certainty, as we watch it in higher and higher scales. Imagine we just watch/observe that CA world by using bigger and bigger tiles, calculating average particle number/velocity/acceleration for each tile. Then the CA world starts following the rules of classical physics (Navier-Stokes Equation), better and better. Meaning the future becomes better and better predictable, as we observe the CA world in higher and higher scales.
Which is very similar to how future events are unpredictable with certainty in QM scale, compared to how future events are predictable with certainty in Relativity scale. And predictability of future events, is in between those two extremes, in Newton Mechanics (human) scale.)

If what are above are assumed to be true, then it would mean somehow quasiparticles of the Planck-scale medium, are allowed to exist only as a discrete and limited set, which are the elementary quantum particles of Standard Model. (So nothing like soap bubbles, which have a continuous size range, and also have identical/similar nature.)

Also obviously this Planck-scale medium has a limited max signal/information travel speed which we call the speed of light (c). So quantum particles without rest mass always travel at c.
And quantum particles with rest mass travel at lower speeds depending on their rest mass plus kinetic energy. What slows them down I am guessing is the Higgs particle field across our Universe.

So rest mass is like a binary property of elementary quantum particles, with possible values of 0 or 1. So if it is 1 then it creates a drag, moving thru the Higgs Field, because of interaction with it. Then its speed thru the Higgs field depends on its total energy (rest mass/energy plus kinetic energy, which determines size (wavelength) of the particle). And if its total energy is greater, then its size/wavelength is smaller, and it moves faster thru the Higgs field and so thru spacetime.

I think Standard Model is not complete and there are at least two more elementary particles to be discovered. I think one of them is Planck Particle and it must be what Black Holes are made of. I think the other must be the particle of Dark Matter (could it be graviton?).

Based on the ideas above, I think the recent discovery of "hot gas" in DM clouds/filaments, must be because of DM creating a positive spacetime curvature, which means higher probabilities for positive energy/mass virtual particles of quantum vacuum. (So it is a similar phenomenon to Hawking Radiation.)

But why elementary quantum particles have quantum properties/abilities like entanglement? I think it could be because reality is created by a Cellular Automaton Quantum Computer (CAQC) with Planck scale cells. So, since elementary quantum particles of SM are the quasiparticles of this CAQC, they also have quantum properties, since they are clusters of qubit information processed by a (CA) QC.

If gravitational fields are fields of (positive) spacetime curvature, and spacetime is a medium created by virtual particles, then how objects would attract each other? Obviously, a vacuum region with higher probabilities for positive energy/mass virtual particles, must be like a low pressure gas region of spacetime medium. And a vacuum region with higher probabilities for negative energy/mass virtual particles, must be like a high pressure gas region of spacetime medium. (Imagine each particle with positive energy/mass, is a region of positive curvature (of the Planck-scale medium), so when they group together in clusters (objects with mass), then they create a macroscale positive curvature region, like a low pressure gas region of the gas-like spacetime medium.)

The Table Of Elementary Quantum Particles

I think discovery of the Periodic Table (PT) of chemical elements, allowed accurate prediction of many new/unknown elements and their various properties. (If we are given, only atomic number and mass number of an element, can we accurately predict all its properties (nuclear, chemical, physical, electric, magnetic), using only Quantum Mechanics?) So the set of all chemical elements clearly have a basic (and standard) order (PT)! But there are also many known (and useful) alternative periodic tables (APT). (Isn't there any precise (and unique) mathematical/geometric object/structure/group/graph for the set of all chemical elements other than various table structures?) (And if so, then that object can explain all basic properties of all elements?) So we could say, the order of the set of all chemical elements is not really unique!

Do we really have any true equivalent of PT/APT for elementary quantum particles (of Standard Model)? I think the answer is really no! Because we could not found any clear order for energy/mass of elementary quantum particles, so far!

I think if there is truly no order (can we ever hope to prove that mathematically?), then it could be viewed as a sign of multiverse (or Intelligent Design?)! And if there is an order and its unique, then it could be viewed as a sign of natural inevitability of our reality/universe. My guess is, it will turn out similar to PT/APT situation of the set of all chemical elements (a non-unique order)!

What we can do to find it/them, if really exist?

I think as a first step, we should try to create a basic (and standard) table for elementary quantum particles. It needs to be sorted by particle (rest) energy (since we are trying to explain order of that primarily), and it surely needs to be simplified using Planck Units.

Here is a proposal for a basic (and standard) table of elementary quantum particles:

Column 0: Name/symbol of the elementary particle

Column 1: Compton Wavelength of the elementary particle in Planck Length Units

Column 2: Corresponding Compton Frequency of the elementary particle

Column 3: Is the elementary particle have rest mass?: Y/N

Column 4: Electric Charge (in Electron Charge units) (Or, is there a Planck unit for electric charge?)

Column 5: Spin

Column 6: Color Charge

(Table needs to be sorted (ascending/descending) by column 1 values, by default.)

Production Of Quantum Particles

How quantum particles maybe produced by our Universe?

Assume our reality is created by a CA QC operating at Planck Scale.
Assume it creates a Planck Scale Particle based fluid medium, just like LBM (CA) creates 2d/3d fluid simulation.
Assume, when that fluid medium starts boiling, it creates bubbles (which are its quasiparticles).
And since the cells of the CA QC are qubit (register(s)) based, those bubbles/quasiparticles have quantum properties.

So assume, our universal fluid medium, creates bubbles/quasiparticles (quantum particles),
as (positive/negative energy) virtual/real single/pair particle/antiparticle, depending on local conditions.

Assume, our perception of spacetime is created by virtual particles of quantum vacuum.
Assume, gravitational field is polarization of spacetime.
Assume, positive spacetime curvature is actually quantum vacuum producing more positive energy virtual particles than negative.
Assume, negative spacetime curvature is actually quantum vacuum producing more negative energy virtual particles than positive.
(So Casimir Force is actually creating artificial gravity/anti-gravity!)
And if the (positive/negative) curvature is beyond necessary threshold, then a real particle (pair) is produced, instead of a virtual particle (pair).

So we can say:
Amplitude of spacetime curvature decides virtual or real particle (pair) will be produced.
Sign of spacetime curvature decides positive/negative energy/mass particle (pair) will be produced.
Polarization/Rotation/Spin of spacetime curvature (?) decides particle and/or anti-particle will be produced.

Matter And Dark Matter

Assume, in the beginning of The Big Bang, the Universe was a ball of positive energy, in the middle of a medium of negative energy.
Later it started absorbing negative energy and so started expanding.
As its positive energy density dropped below a threshold, DM particles got created near uniformly everywhere. As the Universe continued to expand, DM particles coalesced into filaments of the cosmic web.

The BB also created hydrogen and helium uniformly everywhere.
Later DM filaments provided guidance for matter, stars and galaxies to form. But we must realize this view leads to Baryon Asymmetry Problem!

What if, matter of our Universe got created thru a different mechanism, which is asymmetric?

If we look at our Universe, it looks like matter is coalesced in the central regions of DM filaments/clouds. What if matter is not coalesced, but got created in those central regions of DM clouds?

What if, whenever wherever DM cloud density goes above a certain threshold, particles of Standard Model are created, without their anti-particles? (And then later DM cloud density would drop below the threshold there, like a negative feedback mechanism. And if so that would mean total amount of DM in the Universe must be decreasing over time!)

And what if, DM particles are gravitons with extremely low mass/energy, and so with extremely large size (Compton Wavelength)?
So that maybe why we cannot detect them directly and why they cannot join with each other to create a BH etc. (There maybe a similar rule for them like Pauli Exclusion Principle?)

About Graviton from Wikipedia:

"The analysis of gravitational waves yielded a new upper bound on the mass of gravitons, if gravitons are massive at all. The graviton's Compton wavelength is at least 1.6×10^16 m, or about 1.6 light-years, corresponding to a graviton mass of no more than 7.7×10^-23 eV/c2.[17] This relation between wavelength and energy is calculated with the Planck-Einstein relation, the same formula which relates electromagnetic wavelength to photon energy."

Spacetime Curvature And Speed Of Light

What if Gravity is the 5th emergent dimension? (So mass/energy of a particle is its gravity dimension location (+ or -).
(2D surface of a sphere is bent in 3rd dimension. 4D spacetime is bent in the 5th (Gravity) dimension whenever (+ or -) energy/mass is present.)

When a positive spacetime curvature is present, speed of light must slowdown passing from that location. (Just like light slows down when it enters water from air and refracts.)
And if so, then how index of refraction and current speed of light can be calculated for any spacetime location?

Spacetime curvature (which we can calculate) determines deflection angle (which we can also calculate).
Using Snell's Law:
sin(t0)/sin(t1)=v0/v1=n1/n0
Also if c is the speed when there is no curvature.
And if we plug in the values we know/assume then this is what we have:
sin(t0)/sin(t1)=c/v1=n1/n0

We can calculate total bending (deflection) angle of light (in radians) in General Relativity:
deltaPhi=4*G*M/C^2/R (M:Mass in kg; R:Distance from center in meters; C:Speed of light in m/s; G:6.7E-11)

Assume incoming angle of light is 90 degrees (pi/2 radians) (for refraction index=1 because n=c/v and no spacetime curvature in the first medium):
=> 1/sin(t1)=c/v1=n1/1 =>
1/sin(deltaPhi)=c/v1=n1/1 =>
1/sin(4*G*M/c^2/r)=c/v1=n1/1 =>
n1=c/v1=1/sin(4*G*M/c^2/r) (Index of refraction for any spacetime location bending light)
(=> Possible extreme values:1/0=inf or -inf depending on direction of approach;1/1=1;1/-1=-1 => Range: -inf to +inf)
v1=c/n1=c*sin(4*G*M/c^2/r) (current speed of light for any spacetime location bending light)
(=> Possible extreme values:c*0=0;c*1=c;c*(-1)=-c => Range: -inf to +inf)
(Negative c would mean time is flowing backwards there!? c is the flow rate of time (event information flow (perception) rate) anywhere.)
(So it is not possible to make time move faster than c but it can be slowed and its direction maybe changed using negative energy/mass.)
(Light slows down in (positive) gravitational field because it is denser from light point of view. Imagine more positive energy/mass virtual particles on the way.

Gravitational field is actually local polarization of the virtual particle (each with + or - energy/mass) balance at any spacetime location.) If the total net energy is negative then curvature would be negative. Then index of refraction would also be negative.

(The speed of light anywhere is speed of information flow between the CA cells which determine perception of events in Relativity by any observer.)
