What stands where nothing can be seen? For decades scientists have been puzzled by the greatest mystery of the Universe: Dark Matter. An invisible
form of matter is spanning all across the cosmos. Although it can never be seen, we do know it is there; for its sheer mass is bending spacetime
itself, giving mass to our galaxy and preventing its stars - including our Sun - from flying out to the depths of intergalactic space.
But this mystery has just been shattered. For the very first time in History, a set of particles have revealed themselves - as natural implications of
the SPP Theory. Their high mass, their unability to emit or absorb light, and their particular interaction profile, is clear evidences that they might
actually compose nothing less than Dark Matter itself - one of the greatest unsolved problems in physics.
Ladies and gentlemen, I present to you... Dark Matter.
models every single particles of the Standard Model (including their
behaviour) by attributing the concept of compositness to them. A subject of controversy amongst the more conservative sphere of physics, compositeness
is the theory that "elementary" particles are actually composed of preons, tiny building blocks which by themselves compose quite literally
everything. SPPT models conventional particles as sets of 6 preons, all forming tiny octahedrons (diamond-shaped configuration). As an unexpected
side-effect, the SPPT also predicts the existence of stable particles with 4 preons (since they can form platonic solids, tetrahedrons). Five of such
exotic particles emerge up from the model, and they happen to fit exactly the estimated properties of Dark Matter. These five particles are o (for
"obscure"), the antiparticle of o, l (for "lightless"), the antiparticle of l, and i (for "invisible"). Their existence would finally map the
until-now uncharted territory of dark matter and complete the Standard Model:
These five particles would be permeating space all around us (even around our very atoms), giving the Galaxy its mass and enabling our sun to maintain
a relatively stable orbit around the Core.
A Brief Exploration of Dark Matter
Unlike photons, Dark Matter particles have only 4 preons. They simply do not have enough preons to form photons. In other words, Dark Matter cannot
turn into light. Passing photons simply ignore the particles, leaving them in their eternal darkness. Thousands of light-years of dark matter would be
as transparent to light rays as if it was never there.
Dark Matter particles cannot form conventional colours (an important feature of the Strong Force) - this explains why they cannot interact with normal
matter via the Strong Force.
Just like it was predicted of WIMPs, dark matter particles can interact with normal matter via Weak Force bosons. They can exchange preons (exchanges
which briefly form a weak boson) with normal matter particles. The table below gives a rough guess of the possible mode of weak interactions between
normal matter particles and dark matter particles:
Exchanges are done in packets of 3 preons. i particles do not have enough preons of the same flavour, this explains why i is the only dark matter
particle which can never interact with any particles. But this has quite interesting implications; for instance, a container made of i dark matter
could store antimatter forever.
The Mass of Dark Matter
The high mass of the SPPT dark matter particles is infered by none other than the so-called "Mass Paradox" principle itself. In short, individual
preons are more massive than the particle they compose. So, particles with 4 preons will be more massive than particles with 6 preons. But by how
much? Fortunately for us, the SPP Theory gives us a clue. In the SPPT, the decay of an up quark is modelled as an event involving four groups of 3
preons each - an event whose total mass is about 80,400 MeV, that is, the mass of the W boson. The mass of one group of 3 preons can thus be measured
to be about 20100 MeV (80,400 divided by four). Since the mass of a group of 4 preons would stand at 2/3 the difference between the mass of the
3-preons system and the mass of the 6-preons system, then it follows that 4-preons dark matter particles would be about 13,400 MeV.
This means that if a closed system contains both dark matter particles and hydrogen atoms at equal amounts, the dark matter would be responsible for
about 93% of the mass in the system. This is quite close to the actual estimated ratio of the Universe, which is 84.5%. The actual lower ratio is
explained by the fact that the Universe isn't composed of just hydrogen but also of heavier atoms.
This mighty gravitational pull from dark matter particles are the only way dark matter can interact with the universe, besides interaction via Weak
CHAMPs or WIMPs? Finally Settling the Debate
Now according to the general consensus, dark matter out there would most likely be made of electrically-neutral particles (WIMPs). This gave rise to a
considerable debate which is still raging today. Although there are some evidences that dark matter is made of charged massive particles (CHAMPs), the
consensus is that dark matter has zero electric charge. But now four out of the five dark matter particles in the SPPT carry charge - so is dark
matter neutral or not? The answer to the debate lies in a period of the Universe called the Photon Epoch.
Remember that dark matter cannot annihilate into photons. They simply cannot form photons (not enough preons). Thus, at the beginning of the Universe,
when all of matter coupled with its corresponding antimatter (the Photon Epoch of the Universe, which has been called that way because annihilation
gives off light), dark matter did the same with its corresponding dark antimatter. But whereas matter annihilated upon contact with its antimatter,
dark matter failed to do the same upon coupling with dark antimatter.
Thus, to this day, the majority of dark matter would be populated with pairs of coupled dark matter / dark antimatter particles. The total electric
charge of such pairs is zero, thus it explains why dark matter has never been observed to electrically interact with the visible universe. In
themselves, dark matter particles are charged CHAMPs, but they really are forming neutral WIMPs all across the cosmos.
The Invisible Kingdom
Simply put, the part of our galaxy which we cannot see would be mysterious no more. We would finally know the nature of one of the greatest features
of our universe. Entire seas of dark matter, made of particles which are so forsaken by light that they cannot even annihilate, would be flooding
space over intergalactic scales and giving the Universe most of its mass. The invisible ocean of the dark matter particles would be rotating and
circling the galaxy, like a ghost never seen; but nevertheless giving weight to our galaxy - and like a cosmic guardian keeping the stars inside the
And at last, we might have five leads to explore this invisible territory.
