What is mass?

A photon is the smallest piece of light. Light always goes straight, as fast as anything can go, and it hides the space behind it.

If a photon gets curled into a loop it goes around and around, and it keeps hiding the space inside. That trapped light is what we call mass. Everything you can touch is made of trapped light.

Inside (left): the photon runs around and around and hides the space in the middle.

Outside (right): you cannot see the hidden space at all, only a dot. But all the lines of space around it lean in toward it. That leaning is how you can tell something is there, and it is what makes things fall (next page).

Mass: a closed path hiding space, and what speed does to it

A photon is the smallest piece of light; this page follows one photon closed into a loop, the electron, and the space it hides. Light runs at c and hides the space behind it. Close its path into a loop and it hides a fixed amount of space every cycle; that hidden total is the inertial measure, mass. Seen from inside (panel 0) the loop is a path at c around a missing disk. Seen from outside (panels I to IV) the missing space cannot be seen at all: there is only a point, and every line of space that passes it leans in, the lines that would have crossed the missing disk meeting at the point and continuing. The electron sets the scale, ฦ›โ‚‘ = ฤง/(mโ‚‘c) = 386.16 fm, the frameworkโ€™s single calibration.

No inverse-square law is used to draw any line; it appears in IV only as a printed number beside the computed value.

What speed does: the same loop, seen moving

Nothing about the loop changes and the light still runs at c. Seen from a laboratory it is moving past, its cycle takes ฮณ times longer, the photonโ€™s path opens into the curve drawn, and the loopโ€™s outline is squeezed to R/ฮณ along the motion. In the loopโ€™s own frame the path is the closed circle and head meets tail at the same place every cycle; from the laboratory the point where head meets tail is itself moving, so the path never rejoins where it started (the small pinch marks). The mass seen is ฮณ times the rest mass. In the textbookโ€™s letters this is E = ฮณmcยฒ, and the first two terms of that are the rest energy mcยฒ and the kinetic energy ยฝmvยฒ.

This map is the drawingโ€™s construction of two lines of the Mathematical Bridge, section 3: the loop โ€œremoves a volume of available transverse area from the surrounding space, fixing the missing volumeโ€, and โ€œthis deficit propagates outward with profile ฮ”g(r) ~ 1/rยฒโ€; it removes exactly ฯ€ฦ›โ‚‘ยฒ from every circle around the point, and its missing share ฮด = ฦ›โ‚‘ยฒ/rยฒ is exactly the inverse square. Every grid line is the image of a straight line under that map; lines that crossed the disk are drawn through the point and out the other side. Annotated values: the closest pass of a line is its seen radius โˆš(xโ‚€ยฒ โˆ’ ฦ›โ‚‘ยฒ); the curvature ฮบ is evaluated where the line crosses the centre line, its maximum; Rarc = 1/ฮบ. Panel IV prints ฮด at each lineโ€™s true offset xโ‚€ beside (ฦ›โ‚‘/R)ยฒ at its seen radius.

Defining mass: a closed path and the space it hides, the full derivation

A photon is the smallest piece of light; this page follows one photon closed into a loop and derives what the high school page stated. A region of space is hidden; from outside the missing space is not observable, there is only the point and its effect on every line of space that remains. That is the definition of mass. A: the inside view, the closed path and the sphere it hides. B: the map acting on a flat plane through the centre. C: the identical map on the three mid-planes of a block, where every line stays traceable. D: the full block, every radius at once. In B, C and D the lines that met the hidden boundary merge at the point and continue; the crowding and darkening around it is the interaction zone, and the point is the only near-black. Each numbered circle is a panel below.

Why things fall

A photon is the smallest piece of light. The ring is one photon trapped in a loop, like on the mass page. The black dot is a big trapped-light mass, seen from outside: you cannot see its hidden space, only the lines of space leaning in toward it.

Nothing pulls the little loop. The lines of space lean toward the missing space, and the loop just follows the lines it lives in. There is the same time between every picture, and the jumps get longer on their own. That is gravity.

Each loop wears dark green where space is squeezed shortest, the side by the mass, and yellow where space runs longest, the side far away. The squeezed side always wins, so the loop swings toward its dark green.

Inside the little loop the photon keeps going around at the same speed the whole time. Outside, the mass is only a dot; the little arrows under pictures 1 and 5 show how much space is missing at the loopโ€™s near side and its far side. The near side is always deeper, and the pair grows as the loop falls.

Gravity: falling without a force, and who agrees where

A photon is the smallest piece of light; this page follows one photon closed into a loop, standing in the missing-space profile of another loop, a mass. Nothing pulls it. Around a mass the lines of space lean in, and the space itself is not the same on the loopโ€™s two sides: on the near side more of it is already missing. The loopโ€™s photon still runs at c, but its route โ€œleans slightly toward the region with more space already hidden and pays a tiny time premium to get pastโ€ (Bridge Narrative, step 4). That lean, every cycle, is gravity: โ€œno pushes or pulls; cleaner route winsโ€. Far away and slow, it is Newtonโ€™s law exactly; the four classical tests of general relativity come out of the same route picture with one factor set once.

1. Why a loop falls

near side, at r = 2 ฦ›โ‚‘ from the mass: ฮด = 25.0% of space missing; each step here costs twice the far sideโ€™s premiumback side, at r = 4 ฦ›โ‚‘: ฮด = 6.25% missing; over the whole far half the premium is 0.65 of the near halfโ€™sthe loop: one photon at c, radius ฦ›โ‚‘, centre at r = 3 ฦ›โ‚‘; drawn where it is seenthe massthe lean: routes turn toward higher n (ray equation); โˆ‡n here points toward the mass

One loop of light near a mass, drawn on the same mapped space as the Mass page, and drawn where it is seen: through the massโ€™s map its circle appears elongated toward the mass (Bridge Math Appendix, 6A: โ€œits apparent circle elongates toward the curvature sourceโ€). The photon runs at c the whole way round (axiom A2). The space under its two halves is not the same: at the near side, r = 2 ฦ›โ‚‘ from the mass, 25% of the space is missing; at the back, r = 4 ฦ›โ‚‘, only 6.25%. In the Walk-Throughโ€™s cost map, n(x) = 1 โˆ’ 2ฮฆ/cยฒ with ฮฆ = โˆ’GM/r, a step near the mass costs more (โ€œhigher n means this step hides a bit more display-area than averageโ€): the near edgeโ€™s premium is twice the far edgeโ€™s, and summed round the two halves the near half pays 1.53 times what the far half pays (computed, โˆซ(n โˆ’ 1) ds; G cancels in the ratio). The colour runs by that cost per step: green where each step hides the most space, yellow where it hides the least. Routes turn toward higher n, that is the ray equation d/ds(n t) = โˆ‡n, and โˆ‡n at the loop points toward the mass; so every cycle the loop drifts that way. Only the size of the drift rests on G, an acceptance lock. As a seven-year-old put it: just like a Beyblade in a curved bowl, it wants to go toward the centre.

Both arrows of a pair point toward the mass, since gravity has no handedness to flip a side, only depth. The near side is always deeper, and the pair grows as the loop falls. Each loop is painted by the cost map along its rim, n โˆ’ 1 โˆ 1/r at each rim pointโ€™s distance from the mass: darkest green where each step hides the most space (the near side, drawn heavier), darkest yellow where it hides the least (the far side), pale between. The loop always swings toward its dark green.

The point on the right is an electron; its missing space is what bends the grid. The five shapes are a second electron at five distances and five speeds, five separate situations. At rest (1) it hides exactly the same space as the first, ฯ€ฦ›โ‚‘ยฒ each. Moving, its outline is contracted to R/ฮณ along the motion and the mass seen is ฮณmโ‚‘ (the Mass page). Under each, the acceleration between them in the Newtonian limit, a = Gmโ‚‘/rยฒ: about 10โปยนโธ m/sยฒ, which is why gravity between two electrons is never felt, yet the geometry drawn here is the same machinery that runs planets.

4. Who agrees where

Three descriptions, one ladder. Far and slow, everyone tells the same story. Where light bends, is delayed, and clocks drift, Newton falls behind and VMS lands on the tested numbers with general relativity, from one route picture and one factor set once. At the core of a single particle GR runs to infinity where VMS stops, because you cannot hide more space than there is.

2 Gravity ยท Proofthis page on its own

Gravity: two loops and the space between them, the full derivation

A photon is the smallest piece of light; this page follows one photon closed into a loop, the probe, standing in the space another loop has shaped, and derives what the high school page stated. A closed Void path removes a fixed transverse area, the deficit that is its inertial mass. That deficit does not stay local: it propagates outward as an inverse-square curvature of the surrounding space. A second loop, its action computed in that geometry, has its path deflected toward the first; in the weak-field, large-distance limit this is exactly Newtonโ€™s law. Gravity is an emergent property of the geometric deficits carried by the loops, not an imposed field. Left, the probe from inside: its hidden region and the path its photon runs. Right, the source from outside: the missing space, with the lattice drawn into it. The orange curve is the probeโ€™s centre, computed, deflected toward the source. Each numbered circle is a panel below.

1In this case: two loopsThe single-loop case (the Mass page) gives inertia. โ€œTo derive a force law,however, we must consider two loops: a source loop ฮ“ that generates acurvature deficit, and a probe loop ฮ“โ€ฒ whose action is computed within thedistorted geometry created by ฮ“.โ€ Each carries its own loop action,mฮ“ โˆ โˆฎฮ“ Ad ds,  Sฮ“โ€ฒ โˆ โˆฎฮ“โ€ฒ Ad dsand the probeโ€™s is evaluated in the curved geometry ฮ“ generates: โ€œThe geodesicof ฮ“โ€ฒ is deflected toward ฮ“, reflecting gravitational attraction. Evaluating theweak-field, large-R limit yields a mutual force law F(r) = G mฮ“ mฮ“โ€ฒ/rยฒ.โ€In the drawing the probe is shown from inside (its hidden sphere, its photonโ€™spath) and the source from outside (the missing space the lattice leans into).Mathematical Bridge, section 3 (Mass and Gravity), introduction and step 6.Rโ‚€ = 2.5 lattice steps for both loops; the electron would set Rโ‚€ = ฦ›โ‚‘ = 386.16 fm.
2The dent, and its coupling to geometryThe source loopโ€™s stressโ€“energy is the variation of its worldsheet actionwith respect to the metric (the Mass page, panel 6); it is localized on theworldsheet and conserved. The total action is the Einsteinโ€“Hilbert actionplus the Void action:Stotal[g, W] = (1/2ฮบ) โˆซ R โˆš(โˆ’g) dโดx + Svoid[W; g]and varying with respect to gฮผฮฝ gives the Einstein field equations,Gฮผฮฝ = ฮบ Tฮผฮฝโ€œthe precise mathematical statement that a Void loop curves spacetime.โ€The Einsteinโ€“Hilbert term is imported here, with the loopโ€™s Tฮผฮฝ as its source;ฮบ = 8ฯ€G/cโด is โ€œfixed by comparisonโ€ in the Newtonian limit (panel 4): G is anacceptance lock, not an input and not a derivation.Bridge Math Appendix, Mass and Gravity, sections 3 and 5.
3The probeโ€™s motion: geodesic, elongation, no v > cThe second loopโ€™s action is Svoid[Wโ€ฒ; g]; its equations of motion are theminimal-surface equations in the curved g.

A loop can never reach c: โ€œif the loopattempted v > c, the path would fail to geometrically closeโ€; in flat-spacelanguage acoord = aproper/ฮณยณ.

3 What is charge ยท Elementarythis page on its own

Why do things have charge?

A photon is the smallest piece of light. This is one photon trapped, one particle, seen from the inside like before. You saw before how it hides space and makes gravity. The direction it goes makes charge.

Where the head meets the tail you can see how it hides the space around it, strongest up close, fading at the speed of light as it moves away. As it spins, it swooshes a bright ribbon through the grey, the swoosh always curls the same way it spins.
