PHYSICS, STORIES & THE RECORD · 2026.08

Run thephysicsyourself.

Simulations first. Stories and the strange record alongside. You decide what they mean.

The core of this site is a set of interactive simulations: real physics running live in your browser, from orbits and entanglement to starship engines and the search for life. Around them, reviews of books and films that take big ideas seriously, and plain-language notes on the physics. And where the record turns strange, the UAP files are archived too, sourced and labelled, yours to judge.

EIGHT TO START WITH
LIVE A grey trimaran warship, hull number 12, on a deep blue-teal sea in low warm light; a thin seafoam-teal sensor line reaches from its mast to a pale sphere caught at the instant of water entry, half through the surface inside an erupting crown of spray, a wide ring of foam spreading around it. Trans-MediumAIR-SEA FILE · INST-29 A computed ocean: the full FFT wave field running live, a real trimaran hull riding it, and a sphere caught at the instant of water entry. The address the UAP record keeps returning to is the surface of the sea, and this bench builds it wave by wave. LIVE The Space Shuttle orbiter seen from outside in low Earth orbit at orbital dawn: the orbiter rides in the lower left as a mostly dark silhouette, tail and OMS pods toward the viewer, its upper surfaces rimmed in warm dawn light; the Earth's limb sweeps across the frame as one long shallow curve, the night side almost black, capped by a brilliant thin band of dawn orange under a soft teal airglow line; above the limb, three small bright points of light lie along a shallow descending arc like a multiple exposure, the middle one distinctly brighter with a four-spike glint, the third sitting just below the limb line against the dark Earth; sparse stars above, no moon. Three Frames from STS-80LOW-EARTH ORBIT 1996 · INST-55 Three government film frames, one unidentified object, no range. An ice flake at 30 m and a ship at 400 km take the same picture, and this bench stages both worlds to prove it. LIVE A vast dark lens-shaped hull hangs over a dense modern city in low afternoon light, spanning most of the sky; a slender white broadcast tower rises from the streets to just beneath its underside; because the sun stands low on the left, the hull's huge elliptical shadow lies far to the right of the point below it, its clean straight edge cutting across whole blocks, while the buildings directly beneath the hull stand in sunlight; thin haze, no text anywhere. The Mothership LedgerDEDEDEDE · INST-59 Fiction's favourite picture, priced: a kilometre of ship parked over a city, and no rescue clause reaches the shadow. LIVE A grey guided-missile cruiser marked 59 on a calm hazy sea, with a smooth white capsule-shaped object hovering low over the water nearby, above a wide ring of churned white foam. Tic Tac KinematicsNIMITZ 2004 · INST-24 28,000 feet in 0.78 seconds, priced against every g-tolerance ever measured. LIVE A black hole bending the light of the sky around its bright accretion disk. Black HoleGR · INST-02 Spacetime as a lens: a raymarched horizon that bends the whole sky around itself. LIVE A night scene high over interior Alaska: a Boeing 747 freighter in the middle distance flies away toward the lower left, a dark silhouette picked out by its red and green navigation lights, over faint moonlit snow, spruce forest and braided river channels; low on the far left a nearly full moon glows through thin cloud; to the right of the aircraft, low above the horizon, hangs one brilliant golden point of light brighter than every star, with a second, fainter reddish point further right and slightly lower; a faint band of Milky Way climbs from behind the aircraft toward the top of the frame, and a deep-red afterglow stripe lies along the far right horizon; no text anywhere. JAL 1628: The Star BenchALASKA 17 NOV 1986 · INST-62 A 747 crew watched it pace them for half an hour. The pacing was Jupiter; the first act still has no identity. LIVE Cinematic torchlit interior of the King's Chamber of the Great Pyramid: a long rectangular room of rose-brown granite blocks with paper-thin joints, a single burning torch bracketed to the left wall throwing volumetric rays through drifting dust, and the air filled with a three-dimensional lattice of small square motes visualising a standing sound wave, ember-red where acoustic pressure runs high and pale blue where it runs low, converging on a bright nodal line at the centre of the room; a dark granite coffer stands at the far end and tiny unlit rectangular shaft mouths interrupt the side walls. The King's Chamber Resonance BenchKING'S CHAMBER GIZA · INST-66 A famous book made this granite room the core of a planetary machine. The bench runs the numbers it never did: C, not F#. LIVE A close view of 1977 tractor-feed computer printout in low light, sparse green-phosphor characters in columns, one vertical column reading 6EQUJ5 circled in red ballpoint with the handwritten word Wow! beside it. The Wow! Signal6EQUJ5 · INST-22 72 seconds, thirty times the noise, never seen again. Replay the night.

LIVE A museum-lit close study of a tapered cylinder of rose-red Aswan granite standing on a dark pedestal against blackness: a hand-sized ancient drill core, its speckled surface crossed by a fine shallow groove winding around the stone with about a millimetre and a half between traces, a warm key light raking across the crystals from the upper right, a faint translucent ghost of a copper tube drill enclosing the core, and darkness beyond the pedestal edge. The Core No. 7 Feed-Rate BenchPETRIE CORE NO. 7 · INST-67 LIVE Cinematic torchlit interior of the King's Chamber of the Great Pyramid: a long rectangular room of rose-brown granite blocks with paper-thin joints, a single burning torch bracketed to the left wall throwing volumetric rays through drifting dust, and the air filled with a three-dimensional lattice of small square motes visualising a standing sound wave, ember-red where acoustic pressure runs high and pale blue where it runs low, converging on a bright nodal line at the centre of the room; a dark granite coffer stands at the far end and tiny unlit rectangular shaft mouths interrupt the side walls. The King's Chamber Resonance BenchKING'S CHAMBER GIZA · INST-66 LIVE A winter pine plantation at night seen at standing eye level down a dark forest ride: tall frost-dusted Corsican pines flank a frozen track under a crisp starry sky with a faint band of Milky Way; far down the ride, exactly at eye height on the horizon between the trunks, a single brilliant golden-white light flares mid-flash, throwing a thin horizontal streak and a soft halo into the night mist; in the middle distance three small silhouetted figures in cold-weather parkas stand on the track, one aiming a weak warm flashlight beam low at the ground; one bright star hangs low in the sky at right; no moon in frame, no text. The Rendlesham LightRENDLESHAM FOREST 1980 · INST-65 LIVE A night scene high over a black sea off the New Zealand coast: an Armstrong Whitworth Argosy freighter flies away from the camera toward the upper right as a dark silhouette, its twin tail booms running back to two vertical fins joined by a high tailplane, four turboprops turning under a straight high wing, landing gear up; a red navigation light burns at the port wingtip on the left of frame and a green one at the starboard wingtip on the right, with a warm glow at the cockpit windows; out past the starboard wing hangs one soft amber-white orb of light, the brightest thing in the frame, and the sea directly beneath it is dark with no reflection on the water; far below toward the lower right a tight cluster of brilliant white points glows like a distant squid fishing fleet, each sparkling on the swell; a thin line of shore lights traces a coastline under low black hills along the left horizon; the Milky Way stands over the aircraft in a deep indigo star field with one bright bluish-white point high in the upper left; there is no moon anywhere in the frame. The Kaikoura LightsKAIKOURA COAST DEC 1978 · INST-64 LIVE A dark laboratory bench: a mid-century magnetic-sector mass spectrometer, its vacuum flight tube running from a small glowing ion source through a massive C-cored blue-grey electromagnet, where a single beam splits into three thin luminous ion beams that fan apart around the bend, the violet one riding the widest arc on the outside, amber in the middle, and the brightest white-blue one on the tightest arc inside, arriving at three narrow collector slits; on the bench beside the instrument a shallow glass dish holds a few dull grey metal fragments, the room dark around pools of cool instrument light. The Ubatuba MagnesiumUBATUBA SEP 1957 · INST-63 LIVE A night scene high over interior Alaska: a Boeing 747 freighter in the middle distance flies away toward the lower left, a dark silhouette picked out by its red and green navigation lights, over faint moonlit snow, spruce forest and braided river channels; low on the far left a nearly full moon glows through thin cloud; to the right of the aircraft, low above the horizon, hangs one brilliant golden point of light brighter than every star, with a second, fainter reddish point further right and slightly lower; a faint band of Milky Way climbs from behind the aircraft toward the top of the frame, and a deep-red afterglow stripe lies along the far right horizon; no text anywhere.

T-01 Even the astronauts saw them. Then they said what it was. Nine files on this site hold the primary paperwork behind the most repeated sentence in the subject: Mercury and Gemini transcripts, Apollo debriefs, Skylab crew sessions, lunar frames and three shuttle photographs. In most of them the crew identifies the object within a few lines. This page is about the ones that are left. Read the full claim → T-02 The instrument between you and the sky. Across seven files on this site, the same thing keeps happening: a display mode, a lens, a gimbal or a refresh rate produces an effect that then gets read as the object's behaviour. This is the catalogue, and the limits of what it licenses. Read the full claim →
