The Physics

An anomaly in the cosmic microwave background (see CMB), first spotted by the WMAP satellite and confirmed by Planck. The temperature fluctuations in the CMB are supposed to be statistically identical in every direction — but they're not. One half of the sky has slightly stronger fluctuations than the other. The difference is small, but it's real and it's been measured twice with different instruments. Cosmologists named it the "axis of evil" as a wry acknowledgement of how awkward it is: the standard model (see ΛCDM) predicts no such preference, and has no explanation for why it exists.

The Summo-Verse framework identifies this asymmetry as the predicted residual tidal imprint of the parent Summo approach axis at the moment of the Big Bang.

Everything you can see, touch, or measure with a telescope — stars, planets, gas, dust, people. Protons, neutrons, and electrons. Technically "baryonic" refers to particles made of three quarks (protons and neutrons), but cosmologists use it loosely to mean all ordinary visible matter. Despite feeling like everything, baryonic matter is only about 5% of the universe's total energy content. The rest is dark matter (27%) and dark energy (68%), both invisible and both poorly understood.

Not an explosion in space, but the expansion of space itself. About 13.8 billion years ago, everything we can observe was compressed into an extremely hot, dense state. Since then it has been expanding and cooling. The term was coined mockingly in 1949 by the astronomer Fred Hoyle, who preferred a rival theory — but it stuck. The Big Bang does not say what came before it or what caused it. It describes what happened after, and that description is extremely well-supported by evidence.

What triggered the Big Bang — where all that energy came from, and why it happened — is one of the questions the Summo-Verse framework attempts to answer.

One of the most important observations in the study of dark matter. Two galaxy clusters collided and passed through each other. The hot gas — ordinary matter — was slowed by electromagnetic drag during the collision: it piled up in the middle, glowing in X-rays. But the dark matter halos of each cluster passed straight through each other and continued on, undisturbed. We could see where the dark matter was because it was bending light (see gravitational lensing) — and it was clearly not in the same place as the gas. This directly demonstrated that dark matter does not interact electromagnetically. It only gravitates. It is one of the strongest pieces of direct evidence that dark matter exists and behaves differently from ordinary matter. The Chandra X-ray Observatory image of this collision remains the most cited single piece of direct visual evidence.

The oldest light in the universe. About 380,000 years after the Big Bang, the universe had cooled enough for electrons and protons to combine into neutral hydrogen atoms. Before that, the universe was a hot, opaque plasma — like the inside of a star. Light could not travel through it because it was constantly being scattered by free electrons. The moment atoms formed, space became transparent and light was free to move. That first flash of released light has been travelling ever since. As the universe expanded over 13.8 billion years, this light was stretched from visible wavelengths all the way to microwaves. We see it today as a faint, almost perfectly uniform glow coming from every direction, at a temperature of about 2.725 degrees above absolute zero.

The tiny variations in the CMB's temperature across the sky — one part in 100,000 — encode the seeds of all the structure in the universe: galaxies, clusters, the cosmic web. Mapping these variations with satellites (COBE, WMAP, Planck) is one of the most powerful tools in cosmology.

The large-scale structure of the universe, which resembles an enormous three-dimensional spider's web or sponge. Galaxies and galaxy clusters collect along thin filaments of matter; these filaments connect at dense nodes; between them are vast empty voids, hundreds of millions of light-years across, containing almost nothing. This entire structure grew from the tiny temperature fluctuations visible in the CMB — density variations in the early universe that gravity amplified over 13.8 billion years into the dramatic architecture we observe today. Images of the cosmic web look strikingly like images of neural networks, though the resemblance is coincidental.

The name for whatever is making the universe's expansion accelerate. Discovered in 1998 when two independent teams measuring distances to exploding stars (supernovae) found they were dimmer than expected — meaning the universe had expanded more than it should have if gravity were slowing it down. Instead, something was speeding it up. In the standard model (see ΛCDM), dark energy is represented as a constant energy density of empty space — Einstein's cosmological constant Λ — that acts as a kind of repulsive pressure. It makes up about 68% of the universe's total energy content. What it actually is remains one of the deepest unsolved problems in physics.

The Summo-Verse framework proposes two independent physical mechanisms to replace this unexplained constant with external causes: a growing gravitational imbalance from the parent Summos, and a buoyancy effect as the universe expands into the denser Summo-verse medium.

Matter that has gravitational effects we can measure but does not emit, absorb, or reflect any light or electromagnetic radiation of any kind. We know it is there from several independent lines of evidence: stars at the edges of galaxies orbit too fast for the visible matter alone to hold them in — there must be extra mass; light bends more around galaxy clusters than visible matter could cause (see gravitational lensing); and the large-scale structure of the universe only matches observations when dark matter is included in simulations. It makes up about 27% of the universe's energy content, compared to about 5% for all ordinary visible matter. Its composition is entirely unknown.

The Summo-Verse framework proposes that dark matter inside our universe is debris from the Big Bang phase transition — particles that coupled to the Summo-verse medium's Higgs-analog field but have no interaction with the Higgs field of our universe, and therefore no interaction with ordinary matter beyond gravity.

The point of no return around a black hole. It is not a physical surface — there is nothing solid there — but a mathematical boundary. Once anything crosses it, including light, it cannot escape. The size of the event horizon is proportional to the mass of the black hole: double the mass, double the radius. For the Earth's mass compressed into a black hole, the event horizon would be about the size of a marble. For the Sun, it would be about 3 kilometres across. From the outside, an object falling toward the event horizon appears to slow down and redden as its light struggles against the increasing gravity, eventually appearing to freeze — though it never quite disappears from view. This is a consequence of gravitational time dilation.

Einstein's theory of gravity, published in 1915. Newton described gravity as a force that pulls objects together. Einstein realised it is something deeper: massive objects warp the fabric of spacetime itself — both space and time are bent by mass and energy. Other objects simply follow the straightest possible path through this curved spacetime, and that path is what we experience as gravitational attraction. The greater the mass, the greater the curvature.

General Relativity predicted black holes (confirmed), gravitational waves (detected by LIGO in 2015), the bending of light by gravity (first measured in 1919), the expansion of the universe (predicted before it was observed), and gravitational time dilation (confirmed with clocks). GPS satellites must apply GR corrections continuously or positions would drift by several kilometres per day. It is one of the most precisely tested theories in science.

The bending of light by gravity. General Relativity predicts that light follows curved paths near massive objects, because those objects warp spacetime and light must follow the geometry of space. A massive galaxy or galaxy cluster between us and something more distant acts as a lens — bending, magnifying, and sometimes splitting the light from the distant object into multiple images or arcs. By measuring how much distortion is produced, astronomers can calculate the total mass doing the lensing — including the invisible dark matter. It is one of the primary methods for mapping dark matter across the universe.

A theoretical prediction by Stephen Hawking in 1974: black holes slowly emit a faint thermal radiation, caused by quantum mechanical effects near their event horizons. The temperature of this radiation is inversely proportional to the black hole's mass. This means small black holes are much hotter and evaporate faster; large ones are almost imperceptibly cold and barely radiate at all. A black hole with the mass of our Sun would emit Hawking radiation at a temperature billions of times colder than the CMB — completely impossible to detect. No Hawking radiation has ever been directly observed. The mathematical derivation is, however, widely accepted as correct and represents a profound connection between quantum mechanics, thermodynamics, and gravity.

The original Summo-Verse proposal suggested dark matter was an exotic form of Hawking radiation from Summos. This was closed as an error: because Hawking temperature falls as mass increases, Summo-scale singularities would radiate at temperatures indistinguishable from absolute zero — the opposite of what the proposal required.

The Higgs field is an invisible field that exists throughout all of space in our universe. Particles that interact with it acquire mass — the stronger the interaction, the more massive the particle. Particles with no interaction (like photons, the particles of light) travel at the speed of light and have no mass. Without the Higgs field, no particle would have mass, atoms could not form, and stars, planets and people could not exist.

A useful analogy: imagine the Higgs field as a roomful of party guests. A celebrity walks in and attracts a following crowd that slows them down — they gain effective mass from their interaction with the crowd. A nobody walks through unnoticed and moves freely. The Higgs boson is the particle associated with this field — the detectable quantum ripple in it — in the same way that the photon is the particle associated with the electromagnetic field. It was confirmed experimentally at CERN's Large Hadron Collider in 2012.

The Summo-Verse framework proposes that the Summo-verse medium has an analogous structural property — a Higgs-field analog — that confers effective mass on objects moving through it. This is not a claim about the Higgs boson specifically; it is a claim that the mechanism of mass-conferral through field interaction may be a general feature of physical vacuums rather than unique to our universe.

A discrepancy in measurements of the Hubble constant — the number that describes how fast the universe is currently expanding. When measured using the CMB (which tells us about the early universe), you get one value. When measured directly using nearby supernovae and variable stars, you get a higher value — meaning the universe appears to be expanding faster than the early-universe measurements predict it should be. The gap is now large enough that random measurement error is an unlikely explanation. It may indicate missing physics in the standard cosmological model, though its origin remains actively debated.

The standard model of cosmology — the best current description of the universe's composition, history, and large-scale structure. Lambda (Λ) is Einstein's cosmological constant, which represents dark energy: a constant energy density of empty space that drives accelerating expansion. CDM stands for Cold Dark Matter, where "cold" means the dark matter particles move much slower than light speed, allowing them to clump together under gravity and form the scaffolding for galaxies and cosmic structure.

ΛCDM is consistent with measurements of the CMB, the distribution of galaxies, the abundance of light elements, and much else — to a precision of a few parts in 100,000. Despite this success, it does not explain what dark energy actually is, what dark matter is made of, what triggered the Big Bang, or why the CMB has a hemispherical asymmetry. These are among the open questions the Summo-Verse framework attempts to address.

Five special positions in a gravitational system containing two large bodies — like the Earth and the Sun — where a much smaller object can sit in a kind of gravitational balance, neither falling toward one body nor the other. Three of these points are unstable: like a ball balanced on a hilltop, a small nudge will cause the object to drift. The other two (L4 and L5) are stable: objects placed there will stay. The James Webb Space Telescope orbits the Sun-Earth L2 point. Trojan asteroids — thousands of them — cluster at Jupiter's L4 and L5 points. Named after the mathematician Joseph-Louis Lagrange, who worked out their positions in the 18th century.

The Summo-Verse originally placed our universe at a "Lagrange point" between two Summos. This was later refined: our universe sits at the gravitational minimum between two Summos, which is analogous to L1 — the point between the two bodies — but the physics of what happens there is governed by the full framework, not just the force-balance analogy.

A change from one state of a material or a physical field to another, triggered by a change in temperature, pressure, or energy density. The most familiar examples are water boiling into steam or freezing into ice. In cosmology and particle physics, phase transitions happen in quantum fields as they cool. The most significant was the electroweak phase transition in the very early universe — a moment when the Higgs field "switched on" and particles acquired mass for the first time. Before this transition, all particles were massless and the universe was very different from what it would become.

The Summo-Verse framework proposes an analogous phase transition at the flat plane during the Big Bang: the Summo-verse medium's Higgs-analog field, driven to its maximum energy density, converts energy into matter and radiation differentially according to how strongly each type of matter couples to the field. This differential production is the proposed origin of the matter spectrum — ordinary matter, dark matter, and radiation — of our universe.

A point in General Relativity where the equations predict infinite spacetime curvature and infinite density — where the mathematics of GR breaks down entirely. Black holes are predicted to contain singularities at their centres. The Big Bang itself is described as a singularity in the standard model: the universe compressed to a point of infinite density. Most physicists interpret a singularity not as a description of physical reality, but as a sign that General Relativity is incomplete and needs to be replaced or extended by a theory of quantum gravity at these extreme scales. We don't yet have that theory.

The Summo-Verse framework proposes Summos as GR singularities — that is, they are described by General Relativity in the same way a black hole is, not as violations of known physics but as extreme applications of it at scales our equations handle correctly, even if our intuition does not.

The theory describing all known fundamental particles and three of the four fundamental forces: electromagnetism, the weak nuclear force (responsible for radioactive decay), and the strong nuclear force (which holds atomic nuclei together). Gravity is not included — reconciling General Relativity with quantum mechanics is one of the central unsolved problems in physics. The Standard Model accounts for 17 fundamental particles, including quarks (which make up protons and neutrons), electrons, neutrinos, photons (particles of light), and the Higgs boson. It has been tested to greater precision than almost any other theory in the history of science.

When the Summo-Verse papers refer to "Standard Model interactions," they mean the electromagnetic, weak, and strong force interactions described by this theory. The proposal that dark matter has "no Standard Model interactions beyond gravity" means dark matter does not interact through electromagnetism, the weak force, or the strong force — only through gravity, which is outside the Standard Model.

When a gravitational field is not perfectly uniform — stronger on one side of an object than the other — the result is a stretching force. The Moon's gravity pulls more strongly on the side of the Earth facing it and less strongly on the far side; this differential pull stretches the Earth's oceans slightly into an oval, producing tides. Tidal forces are what tear apart comets that pass too close to Jupiter, and what would stretch an astronaut into a thin strand ("spaghettification") if they fell into a black hole. The intensity of tidal forces depends not just on how massive the source is, but on how quickly the field varies across the extended object.

In the Summo-Verse context, the two parent Summos would impose tidal forces across our expanding universe — pulling slightly harder on the side closer to each Summo than on the far side. The framework addresses why this does not produce the gross distortion that would otherwise contradict the observed isotropy of the CMB.

A prediction of General Relativity: time passes more slowly in stronger gravitational fields. The deeper in a gravitational well you are — closer to a massive object — the slower your clock ticks compared to a clock far away from any mass. This is not a metaphor or an instrument error; it is a real physical difference in how fast time passes. Atomic clocks at sea level genuinely tick slower than atomic clocks at mountain altitudes, by a tiny but measurable amount. GPS satellites, which orbit at high altitude in weaker gravity, must correct for the fact that their clocks run faster than ground-based clocks — without the correction, GPS positions would drift by kilometres per day.

Near a black hole, the effect becomes extreme. At the event horizon itself, time would appear to stop from an outside observer's perspective. In the Summo-Verse framework, our universe sits at the gravitational minimum — the weakest-gravity point in the Summo system — and therefore experiences time running faster than anywhere else in the Summo-verse. The Summos themselves, at maximum gravitational potential, experience time most slowly.
