The Expanding Universe — Why Galaxies Run Away From Us

In 1929 Edwin Hubble pointed his telescope at distant galaxies and noticed two things: their light was redshifted (stretched to longer wavelengths), and the further away the galaxy, the larger the redshift. Read as a velocity, this said every distant galaxy is rushing away from us, faster the further it is — Hubble's Law: $v = H_{0} d$ , with $H_{0} \approx 70$ km/s per megaparsec. In 1998 two independent teams measuring Type Ia supernovae found something even stranger: the recession is accelerating, not slowing down as gravity should make it do.

Standard cosmology calls this the expansion of the universe, says "space itself is stretching" (FLRW metric in General Relativity), and patches the acceleration by inserting a cosmological constant

Λ

into Einstein's equations — re-named dark energy since 1998.

Λ

is fitted to data, not derived from any underlying mechanism.

Two huge open questions remain in the standard story:

What is doing the stretching? "Space" in standard physics is a passive coordinate system; coordinate systems do not stretch by themselves. Something must be carrying the stretch — but the standard model gives that something no mechanism, only a label ( $Λ$ ).
Why is the expansion accelerating? A force is needed to overcome gravitational deceleration. The standard model invents "dark energy" — ~68% of the universe's mass-energy content, with no detected microscopic origin and no testable prediction beyond the rate it has been measured at.

What Supreme Polarity Theory says is happening

The time-string is still subdividing. The original One subdivided into two, those into four, four into eight, and so on (see Subdivision — How One Becomes Many). The process did not stop at the cosmic scale we currently observe — it is still going on, right now, everywhere. Every Planck-time interval, the membrane gains a tiny bit more area as new pole-pairs are born along its skin. Cumulative over 13.8 billion years, this geometric growth is exactly the cosmic expansion Hubble measured.

Hubble's Law is a direct fingerprint of ongoing subdivision. The further apart two galaxies are, the more units of subdivision sit between them, so the more new membrane area is created per second between them — and the faster they appear to recede. The proportionality

v = H_{0} d

falls straight out of "every patch of membrane subdivides at the same rate".

There is no "stretching of space" as a separate force. There is just the membrane growing — and what we call "space" is the Càn projection of that membrane. As the membrane gains area, the projection looks bigger from the inside. Galaxies are not moving through space; space itself is gaining area between them, by subdivision, at every moment.

Why distant light is redshifted

A photon emitted by a distant galaxy travels along the membrane toward us. While it is in transit, new pole-pairs are being created beneath it on the very skin it rides on. The photon's flip-pattern, originally drawn against a smaller membrane area, now spans a larger area by the time it arrives — its wavelength has been stretched in proportion to how much new area was created during the journey. We measure that stretching as redshift.

Redshift is therefore not a Doppler effect. Galaxies are not moving away through some pre-existing space and shifting their light by the relative-velocity formula. They are sitting still on the membrane while the membrane itself gains area between them and us — and the photon, born on a smaller membrane and read on a larger one, comes out cosmologically redshifted. The distinction matters: the standard "velocity" interpretation breaks down at $z ≳ 1$ because no real galaxy can travel faster than $c$ , but cosmological redshifts of $z = 10$ and beyond are routinely observed. SPT has no such trouble — the membrane can subdivide as fast as it wants without anything moving through anything.

Redshift = cumulative new-area-per-unit-distance. The Hubble constant

H_{0}

is, in SPT terms, the rate at which the membrane gains area per unit existing area per unit time — a true geometric property of the time-string, not a free parameter.

Why there is no edge and no centre

If every distant galaxy is rushing away from us, are we at the centre of the universe? No. Subdivision happens everywhere on the membrane simultaneously. From the point of view of an observer in any galaxy, every other galaxy looks like it is rushing away — because the membrane area between any two points is growing. There is no preferred centre; every position sees the same Hubble-Law recession from itself. We see ourselves at the centre because every observer in the universe sees themselves at the centre.

Likewise there is no "edge" of the universe to bump into. The membrane is, geometrically, a closed surface that grows by subdividing internally — not by extending into some external void. Standard cosmology has trouble explaining what "outside" the universe could mean; SPT has no need for an outside, because the time-string is the universe and there is no "outer space" beyond its skin.

Why the expansion is accelerating

Standard cosmology has no native explanation for the acceleration. Without dark energy the expansion should slow down (gravitational attraction between matter pulls it back); the observed acceleration must be supplied by adding $Λ$ by hand. Supreme Polarity Theory predicts the acceleration directly, with no free parameter:

More membrane area ⇒ more nodes per slice. As the membrane subdivides, every existing area generates new node-pairs in every slice (Càn and the seven non-Càn slices). Total node count grows as the membrane area grows.
More nodes in non-Càn slices ⇒ more outward pressure. As described in Empty Space Is Also Tai Chi Nodes, the seven non-Càn slices contribute a steady outward pressure on the Càn projection — what we measure as dark energy. The size of that pressure is proportional to the number of non-Càn nodes per Càn-area.
Subdivision adds non-Càn nodes faster than gravitational drag can pull them back. The seven slices' outward push grows with the total membrane area (which is itself growing). Result: the expansion accelerates on its own — no extra dark energy parameter needed, just the geometry of subdivision.

Dark energy is not a substance. It is the name we give to the cumulative outward pressure of the seven non-Càn slices on the Càn projection — and that pressure grows because the membrane keeps subdividing, adding new non-Càn nodes proportional to the area. The accelerating expansion is the geometric consequence of ongoing subdivision, not a postulated extra force.

Why nearby galaxies still attract while distant ones recede

Andromeda is approaching us at ~110 km/s and will collide with the Milky Way in ~4.5 billion years — even though Hubble's Law applies to it too. Why? Because at small enough distances, gravitational phase-coupling between phase-locked clusters wins over the membrane growth between them. The two effects always coexist:

Membrane growth (everywhere): adds new area between every pair of points proportional to their separation $d$ — pulls them apart at rate $H_{0} d$ .
Phase-coupling attraction (between bound clusters): pulls them together with strength that depends on their masses and falls off as $1/ d^{2}$ .

Below a critical separation (within the Local Group, the Local Supercluster, anything gravitationally bound), phase-coupling dominates and the cluster stays together — Andromeda and the Milky Way will merge. Above that separation, membrane growth dominates and the recession wins — distant galaxy clusters are slowly being carried apart from us at $H_{0} d$ . Both effects act everywhere; only the balance shifts with distance.

Stellar nuclear fusion as Tai Chi Node bonding — a third, local brake on expansion

Membrane growth (subdivision) and gravitational phase-coupling are not the only two forces shaping cosmic expansion. There is a third, more concrete mechanism running constantly inside every star in the universe: nuclear fusion, which in Supreme Polarity Theory is literally the forging of new Tai Chi Node bonds. Every fusion event in a stellar core is the inverse of subdivision — separate nodes phase-locking together into a tighter, more coherent pattern — and across the $\sim 1 0^{22}$ stars in the observable universe, the cumulative effect is a real, measurable brake that subtracts from the membrane's free area growth.

The mechanism in SPT terms. A stellar core is an extreme in-phase, in-spin environment — billions of node-clusters (atomic nuclei) compressed together, all spinning roughly in-phase, all flipping coherently at very high frequency (which is why the core is hot, dense, and bright). When two light nuclei (themselves small phase-locked clusters of nodes) are pushed close enough that their spin axes lock and their flip patterns synchronize, they merge into a single larger phase-locked cluster. This is fusion. Two protons + two neutrons (4 separate phase-locked clusters) become one helium-4 nucleus (1 deeper phase-locked cluster). The net node count participating in independent flip-spin drops by 3.

Why this slows expansion. Recall that membrane growth (the engine of Hubble recession) happens because every patch of free, in-phase-flipping membrane births new pole-pairs proportional to its area. A region whose nodes are heavily phase-locked into a single deep bound cluster behaves as one node from the membrane's subdivision-counting perspective, not as many. A locked-in cluster cannot freely subdivide its bound region — the in-phase pull holding it together suppresses the spawning of new pole-pairs inside the binding volume. So every new Tai Chi Node bond forged inside a star locally converts free expansive membrane into locked, non-expanding membrane. The energy released (the photon flash, what we see as starlight) is precisely the spin-energy released when many independent flip-spin patterns collapse into a single coherent one — Einstein's $E = m c^{2}$ in geometric form.

Why the effect is small but real. A single fusion event removes only a few pole-pair degrees of freedom from a tiny patch of membrane. Compared to the sheer volume of free intergalactic membrane subdividing everywhere, this is a marginal correction. But integrated over $\sim 1 0^{22}$ stars × $\sim 1 0^{38}$ fusion events per second per star × $\sim 1 0^{17}$ seconds of cosmic history, the cumulative number of locked Tai Chi Node bonds is enormous. The result: stellar nucleosynthesis has been continuously decelerating the local expansion rate inside every star-forming region for the entire age of the universe, opposing the dark-energy push and partially offsetting the Hubble flow at galactic-cluster scales. This is a third contribution to the Hubble Tension on top of pure phase-coupling: regions rich in stars and active fusion locally measure $H_{0}$ slightly lower than truly empty voids do.

Stars actively reverse subdivision. Every fusion in a stellar core is the forging of a new Tai Chi Node bond — many independent flip-spin patterns merging into one coherent bound cluster. The light we receive from stars is the released spin-energy of that merging. The membrane area locked into the bound cluster no longer participates in free expansion. Across

\sim 1 0^{22}

stars over

\sim 13.8

Gyr, this is a real, geometric brake on cosmic expansion — and one mechanism behind why local measurements of

H_{0}

in star-rich regions read systematically lower than CMB-scale measurements in the diffuse void.

Three local brakes on expansion, in order of strength: (1) gravitational phase-coupling between bound clusters (the dominant effect inside galaxies and clusters); (2) the suppression of subdivision near phase-locked regions (the secondary effect, contributing to the Hubble Tension); (3) ongoing nuclear fusion forging new Tai Chi Node bonds (the third effect, integrated across all stars). All three follow from one geometric rule: phase-locked regions resist further subdivision. Black holes — the most extreme phase-locked regions of all — represent the asymptotic limit of this brake.

If the universe is expanding, did it begin in a Big Bang?

Standard cosmology runs the expansion backwards in time and arrives at a moment of infinite density ~13.8 billion years ago — the Big Bang singularity. The mathematics breaks down there and the laws of physics no longer apply. Supreme Polarity Theory says no such singularity exists. Subdivision is recursive and beginningless: 1 → 2 → 4 → 8 → ... runs forwards forever, but it also makes sense to read it backwards as $\dots \to 8 \to 4 \to 2 \to 1$ and never quite reach "zero". The One was always One, indivisible, and subdivision is not an event that started — it is what the One always does. See No Big Bang — Just the Power of Two for the detailed argument.

What we call the cosmic microwave background — the faint thermal afterglow at 2.7 K — is, in SPT, the long-time-averaged flip-radiation of the membrane during the early dense subdivision phase, redshifted enormously by all the subsequent area growth. Same observation, no singularity required.

Predictions Supreme Polarity Theory makes that standard cosmology cannot

Hubble tension naturally resolved. Local measurements ( $H_{0} \approx 73$ ) and CMB-based measurements ( $H_{0} \approx 67$ ) disagree by ~9%. SPT predicts a tiny systematic difference between local and cosmic-scale measurements because subdivision near a gravitationally-bound cluster is partially suppressed by phase-coupling — exactly the direction and order of the observed tension.
Dark energy is not exactly constant. It tracks the membrane area and so should very slowly grow with time as more area is created. Standard $Λ$ is by definition constant; SPT predicts a slight slow drift, potentially testable by next-generation surveys (Euclid, LSST).
Dark matter and dark energy are linked. Both come from the seven non-Càn slices — dark matter from local clusters, dark energy from the diffuse background. Their ratio should follow a fixed geometric relationship across cosmic history, not the independent evolution standard $Λ$ CDM assumes. Already partially supported by the observed cosmic coincidence ( $Ω_{m} \sim Ω_{Λ}$ today).
No "end of the universe". $Λ$ CDM eventually predicts a heat death where everything is so far apart no interaction is possible. SPT predicts continued subdivision: the membrane keeps gaining area, but new structures keep forming locally because phase-locking is also continuous. The universe never ends — it just keeps subdividing.

The picture in one paragraph

The universe is expanding because the time-string is still subdividing. Every Planck-time, every patch of the membrane gives birth to new pole-pairs, in every slice at once. New Càn area between distant galaxies is what we read as Hubble recession; new non-Càn area is what we read as accelerating dark-energy pressure. There is no Big Bang singularity in the past, no edge of space at the present, and no heat-death in the future — only the One, indivisible at root, eternally subdividing on its skin.
