PHYSICS, STORIES & THE RECORD · 2026.09

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 bright autumn morning outside Melbourne in 1966, seen from behind a crowd of secondary students in grey uniforms, boys in caps and shorts, girls in tunics with white collars, pressed against a low post-and-wire fence and all looking south; a young teacher in a tweed jacket shades his eyes; beyond the fence waist-high dry paddock grass, a dirt road with a drainage ditch and market-garden rows to the left, and on the far horizon a long row of tall dark pines; just above the pine tops a small silver-grey domed disc, flat underneath, about two Moons wide, with no windows or lights; two specks of light aircraft higher in the sky on either side of it; a tall steel lattice pylon at the right with its wires crossing the top of the frame; hard sunlight from behind the left shoulder throwing the students' shadows forward and to the right; a blue sky with thin flat clouds; no text anywhere. The Westall Two-Channel BenchWESTALL 1966 · INST-86 In April 1966, two Melbourne schools watched a silver-grey object drop behind the pines and rise again. The 2014 answer is a sampling balloon from Mildura. Flown on that morning's radiosonde record, it never comes within 400 km. LIVE A night scene on a two-lane Texas farm road through tall pines: a huge diamond-shaped craft hovering over the road ahead, dull metallic with a ring of small blue lights, venting a turbulent column of orange flame downward that floods the wet asphalt with hot light; a 1970s sedan stopped on the road with headlights on, its silhouette rimmed by the glare; far in the background a loose formation of tandem-rotor helicopters with red navigation lights against a cold starry sky. The Radiation DoseCASH-LANDRUM 1980 · INST-73 Two injury cases read as dosimeters: day-18 hair loss sits dead centre in the radiation window, and the '300 Gy' line dies against the survival wall, refuted by the patient's own year of follow-ups. The injuries are documented; the cause was never measured. LIVE A cutaway Moon in three-quarter view against black space: the grey cratered surface sliced open along a vertical plane to reveal a thin bright metallic shell, a vast dark hollow interior and a small glowing core at the centre, rendered as a technical cross-section with faint measurement ticks along the cut. The Hollow MoonJORJANI 2023 · INST-75 The book's hollow Moon needs a shell 2.3 times denser than osmium. GRAIL puts the mass at the centre. LIVE Earth from deep space against a dense starfield: the right half of the globe in daylight, Europe, the Mediterranean and a golden-ochre Sahara lit by hard sunlight from the right, with a single bright golden glint of sun on the Levant coast; the left half in deep night, the Atlantic and the edge of the Americas dark with no city lights; a soft terminator dividing the two, a thin blue atmospheric rim around the limb, and a faint band of the Milky Way in the lower left; no text anywhere. The Long Day at GibeonSITCHIN 1990 · INST-84 Sitchin says the Americas' long night confirms Joshua's sun. Freeze the terminator: half the planet is always dark. 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 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 hull riding it, and a sphere caught at the instant of water entry. LIVE High over a blue tropical sea dotted with small clouds, a silver MiG-21 crosses the upper left of the frame, its rear fuselage dissolving into a comet-tail of thousands of glittering metal fragments streaming down and back through the air, with no fire and no smoke anywhere; a small bright metallic sphere hangs in the sky to the right of the trail; in the lower right an identical wingman jet flies on, seen from behind and above; hard daylight, no people visible, no legible text. No Smoke, No FlameLACATSKI 2024 · INST-83 'No smoke, no flame. The plane just disintegrated.' The only exit with no wreckage prices as a 57-metre fireball. LIVE A handheld spectrum analyzer standing on a tripod on dark high ground at dusk, its small screen glowing with two clusters of amber spikes; below and beyond, a vast dark basin with a few scattered ranch lights, and on the far horizon a long black mountain wall under a deep blue-orange sky; a faint radio-beam glow sweeps far off near the horizon; no people, no legible text. The Skinwalker SpectrumLACATSKI 2024 · INST-82 Two 'large signals', never seen again. Their spacing is the analyser's filter width, and one radar grazes the mesa.

LIVE A rain-soaked night alley in a Hong Kong-style district: a lone standing figure in a full-body camouflage suit that displays a lit building façade with windows and coloured sign panels across its torso and limbs, so the body reads as half transparent while the pattern it shows does not line up with the real wall behind; a fine crown of water splashes bursts off the top of its hooded head and shoulders; the wet street mirrors the lights, and the pavement immediately under the figure is darker and duller than the rest; on the left a dim façade with air-conditioner boxes, pipes and a roller shutter; on the right, receding down the alley, glowing sign panels in red, blue, green and orange rendered as plain coloured bars with no lettering; a single orange street lamp on a post at the upper right lights the falling rain; teal and magenta haze, shallow depth of field; no text anywhere. The Thermoptic Camouflage BenchOSHII 1995 · INST-88 LIVE Early morning inside the Sphinx Enclosure at Giza, seen from its western end: a straight line of small black geophones on spikes, joined by a thin black cable, runs across the bare weathered limestone floor toward the rump of the Great Sphinx, whose layered back and rounded head rise in the middle distance against a pale sky; on the right the western wall of the enclosure, pale limestone with rounded, undulating weathered bedding; on the left a shadowed rock wall and, beyond it, the corner of a pyramid; a geologist in a khaki shirt and bush hat crouches beside an open field-recorder case reading a paper trace; a sledgehammer lies on a square steel plate in the foreground; low warm sunlight from the right throws long shadows; no text anywhere. The Sphinx Erosion BenchSCHOCH 1992 · INST-87 LIVE A bright autumn morning outside Melbourne in 1966, seen from behind a crowd of secondary students in grey uniforms, boys in caps and shorts, girls in tunics with white collars, pressed against a low post-and-wire fence and all looking south; a young teacher in a tweed jacket shades his eyes; beyond the fence waist-high dry paddock grass, a dirt road with a drainage ditch and market-garden rows to the left, and on the far horizon a long row of tall dark pines; just above the pine tops a small silver-grey domed disc, flat underneath, about two Moons wide, with no windows or lights; two specks of light aircraft higher in the sky on either side of it; a tall steel lattice pylon at the right with its wires crossing the top of the frame; hard sunlight from behind the left shoulder throwing the students' shadows forward and to the right; a blue sky with thin flat clouds; no text anywhere. The Westall Two-Channel BenchWESTALL 1966 · INST-86 LIVE High-oblique aerial view over a pale limestone plateau in the central Sinai at early morning: one vast fresh crater cut into the ochre gravel plain, its raised rim of thrown-out rubble catching hard sunlight from the right, the sunlit inner wall bright and the far wall in deep shadow, the floor a smooth pale grey-green glassy sheet with a low mound at its centre; the ground around the crater bleached paler than the plain, dry braided wadis running across the foreground; to the upper right a broad darker plain of flint gravel with a thin veil of dust drifting away from the crater toward the hazy horizon; white limestone escarpments in the far distance; no people, no text. The Sinai Fallout LedgerSITCHIN 1985 · INST-85 LIVE Earth from deep space against a dense starfield: the right half of the globe in daylight, Europe, the Mediterranean and a golden-ochre Sahara lit by hard sunlight from the right, with a single bright golden glint of sun on the Levant coast; the left half in deep night, the Atlantic and the edge of the Americas dark with no city lights; a soft terminator dividing the two, a thin blue atmospheric rim around the limb, and a faint band of the Milky Way in the lower left; no text anywhere. The Long Day at GibeonSITCHIN 1990 · INST-84 LIVE High over a blue tropical sea dotted with small clouds, a silver MiG-21 crosses the upper left of the frame, its rear fuselage dissolving into a comet-tail of thousands of glittering metal fragments streaming down and back through the air, with no fire and no smoke anywhere; a small bright metallic sphere hangs in the sky to the right of the trail; in the lower right an identical wingman jet flies on, seen from behind and above; hard daylight, no people visible, no legible text.

T-01 The claim that it was suppressed, and the paper that would show it. Elizondo, Puthoff, Lazar and Grusch describe a stigma campaign, threats and compartmentalisation so tight that nothing can be checked. The claim explains why the rest of the record is missing, and that makes it the one claim that carries its own test. This page keeps the paper trail, and updates when a release adds to it. Read the full claim → T-02 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 →
