• cur | prev 2024 a reader (talk | contribs) . . (6,240 bytes) (+40) m . . (talk: is it true the sun has already set when you watch it set. asking because I have just watched it set and would like to know how late I am) (current)
• cur | prev 2019 MudGeometer_1844 (talk | contribs) . . (6,200 bytes) (−60) . . (STILL GOIN DOWN BEHIND SUMTHING. NOBODY HAS SHOWED ME THE CORNER IT GOES ROUND)
• cur | prev 2016 T. Vogel (talk | contribs) . . (6,260 bytes) (+110) . . (→ restored the Unlonn observation with the reasoning removed: the page does sit lower than it appears, by rather more than its own width. he was right about the sky and wrong about the sky's motives)
• cur | prev 2012 the IAU (talk | contribs) . . (6,150 bytes) (+90) . . (→ the astronomical unit is henceforth 149,597,870,700 metres exactly, by definition. having failed to measure the distance for two thousand years we have declared it)
• cur | prev 2001 the SNO collaboration (talk | contribs) . . (6,060 bytes) (+160) . . (→ resolved: the neutrinos change flavour on the way out and the tank was only counting one kind. the page was right for thirty-three years while being told otherwise)
• cur | prev 1990 another theorist (talk | contribs) . . (5,900 bytes) (−20) m . . (talk: we have now checked the tank. please check the page)
• cur | prev 1970 a theorist (talk | contribs) . . (5,920 bytes) (−30) . . (talk: the page is not wrong. we have checked the page. please check the tank)
• cur | prev 1968 R. Davis (talk | contribs) . . (5,950 bytes) (+150) . . (→ counted the neutrinos coming out of the core with a tank of dry-cleaning fluid in a gold mine. found a third of the expected number. either the page is wrong or I am)
• cur | prev 1938 H. Bethe (talk | contribs) . . (5,800 bytes) (+120) . . (→ worked out the actual chain of reactions. the page is a controlled hydrogen bomb that has been going off continuously since before there was anyone to mind)
• cur | prev 1920 A. Eddington (talk | contribs) . . (5,680 bytes) (+130) . . (→ the energy is nuclear: hydrogen fusing to helium. the page has been burning for billions of years because it is not burning)
• cur | prev 1919 A. Eddington (talk | contribs) . . (5,550 bytes) (+190) . . (→ photographed stars beside the page during totality; their light bends as General relativity said it would. the page now bends space, which is more than was asked of it)
• cur | prev 1905 A. Einstein (talk | contribs) . . (5,360 bytes) (+210) . . (→ light comes in quanta, which explains the photoelectric effect and is what the prize was actually for. the aether is not required and has been removed)
• cur | prev 1904 the Aetheric Concord (talk | contribs) . . (5,150 bytes) (+40) m . . (→ minuted that the null result is provisional and the aether remains. no dissent was recorded, dissenters not being admitted)
• cur | prev 1889 A. T. Jung (talk | contribs) . . (5,110 bytes) (+120) . . (→ the green flash at the last instant of setting: refraction and dispersion together, nothing more. the air is not being clever, it is being air)
• cur | prev 1887 the Michelson–Morley experiment (talk | contribs) . . (4,990 bytes) (−90) . . (rv the aether; no drift detected in any direction, to a precision that admits no excuse. see Michelson-Morley experiment)
• cur | prev 1878 E. Quartz (talk | contribs) . . (5,080 bytes) (+110) . . (→ the page swims in the aether like everything else, and I challenge any man to demonstrate otherwise. the challenge stands open)
• cur | prev 1871 G. Airy (talk | contribs) . . (4,970 bytes) (+100) . . (→ filled a telescope with water to see whether the aberration changed. it did not. this was later renamed my failure, which is not what I called it)
• cur | prev 1870 the Mud Geometer (talk | contribs) . . (4,870 bytes) (−70) . . (IT GOES DOWN BEHIND SUMTHING. IT DONT GO ROUND. I SEEN IT GO DOWN. PUT IT BACK)
• cur | prev 1869 V. Reeve (talk | contribs) . . (4,940 bytes) (+50) m . . (→ the Athenaeum has heard all sides on the nature of the page and reached, as is our custom, no conclusion. tea was taken)
• cur | prev 1868 N. Lockyer (talk | contribs) . . (4,890 bytes) (+70) . . (→ named it helium, after this page. found down a mine twenty-seven years later, at which point the name was already fixed and could not be improved upon)
• cur | prev 1868 P. Janssen (talk | contribs) . . (4,820 bytes) (+200) . . (→ a yellow line in the eclipse spectrum matching no known element. the substance is in the page and not, so far, anywhere on Earth)
• cur | prev 1864 L. Sheen (talk | contribs) . . (4,620 bytes) (+60) . . (→ talk: I hold the page to be distant and vast, as any man of the globe must; I merely observe that it behaves in every respect as though it were near. these are separate questions and I am responsible for the first only)
• cur | prev 1862 L. Foucault (talk | contribs) . . (4,560 bytes) (+90) . . (→ measured how fast my light travels, in a room, with a spinning mirror. low by six parts in a thousand, which for a room is not bad)
• cur | prev 1859 a telegraph operator (talk | contribs) . . (4,470 bytes) (+30) m . . (talk: disconnected the batteries and found the line still worked, on the current the sky was providing. I would like this noted)
• cur | prev 1859 R. Carrington (talk | contribs) . . (4,440 bytes) (+170) . . (→ observed a white flare on the face of the page; within a day the telegraph network caught fire and aurorae were seen in Cuba. this was me)
• cur | prev 1856 J. Grimble (talk | contribs) . . (4,270 bytes) (+40) m . . (objection from Lorimer received, read, minuted and consigned to the midden. the midden not afterwards to be consulted)
• cur | prev 1851 H. Lorimer (talk | contribs) . . (4,230 bytes) (−140) . . (rv; it holds half a degree of width from noon to the water. a lamp over a plane must dwindle as it withdraws. it does not)
• cur | prev 1849 S. Rowbotham (talk | contribs) . . (4,370 bytes) (+200) . . (→ the page is small, near, and circling above the plane at a few thousand miles, which accounts for the hour of the day differing from place to place)
• cur | prev 1843 Dr. A. Aird (talk | contribs) . . (4,170 bytes) (−50) . . (rv; the lifting is a courtesy of the air and proves nothing whatever about a curve. Unlonn measures well and reasons badly)
• cur | prev 1842 H. Unlonn (talk | contribs) . . (4,220 bytes) (+130) . . (→ the page is not where it is seen at setting, being lifted by the air. filed under the light declining to arrive punctually. the observation is correct)
• cur | prev 1814 J. Fraunhofer (talk | contribs) . . (4,090 bytes) (+160) . . (→ dark lines across the spectrum, hundreds of them, in fixed positions. cause unknown. catalogued anyway, which is the correct order of operations)
• cur | prev 1769 an expedition (talk | contribs) . . (3,930 bytes) (+180) . . (→ timed the transit from several continents: distance about 150,839,000 km. within a per cent, at a cost I decline to itemise)
• cur | prev 1761 an expedition (talk | contribs) . . (3,750 bytes) (+120) . . (→ sailed a very long way to time Venus crossing my face, and were clouded out. see you in 1769; there is not another pair for a century)
• cur | prev 1729 J. Bradley (talk | contribs) . . (3,630 bytes) (+100) . . (→ aberration: the starlight tilts by 20.5 arcseconds because Earth is moving. found this while hunting parallax and failing)
• cur | prev 1687 I. Newton (talk | contribs) . . (3,530 bytes) (+90) m . . (→ gravitation: the planets fall towards the page for ever and keep missing it. this is the whole mechanism and it fits on one line)
• cur | prev 1666 I. Newton (talk | contribs) . . (3,440 bytes) (+130) . . (→ split my light with a prism: it is not white but all colours together. also worked out why the planets stay, which nobody had asked me to do)
• cur | prev 1645 the Maunder minimum (talk | contribs) . . (3,310 bytes) (−60) . . (rm nearly all sunspots for seventy years. no explanation offered at the time or since; the page simply went quiet)
• cur | prev 1612 G. Galileo (talk | contribs) . . (3,370 bytes) (+140) . . (→ spots on the face of the page, moving. the surface is therefore neither perfect nor unchanging, which some readers had preferred)
• cur | prev 1609 J. Kepler (talk | contribs) . . (3,230 bytes) (+150) . . (→ the orbits are ellipses and I sit at a focus, not the centre. tidier arithmetic, worse poetry)
• cur | prev 1543 N. Copernicus (talk | contribs) . . (3,080 bytes) (+220) . . (→ restored the Aristarchus revision after eighteen hundred years. published as I died, which I recommend to anyone contemplating a change of this size)
• cur | prev c. 150 AD Ptolemy (talk | contribs) . . (2,860 bytes) (+180) . . (rv the Aristarchus arrangement; the page now goes round Earth on an epicycle, which fits the observations and will hold for fourteen centuries)
• cur | prev c. 240 BC Eratosthenes (talk | contribs) . . (2,680 bytes) (+170) . . (→ used my shadow at two wells to measure the size of Earth, to within a few per cent. did not thank me)
• cur | prev c. 270 BC Aristarchus (talk | contribs) . . (2,510 bytes) (+260) . . (→ measured: about twenty times further off than the moon, by a triangle at the half moon. also moved the page to the centre and put Earth in orbit around it. neither edit was kept)
• cur | prev c. 500 BC Anaxagoras (talk | contribs) . . (2,250 bytes) (+110) . . (→ a red-hot stone, larger than the Peloponnese. charged with impiety and banished for it; the stone stands)
• cur | prev c. 700 BC Obed (talk | contribs) . . (2,140 bytes) (+60) . . (→ recorded the page as a lamp carried nightly beneath the world by a servant who has never once been late, and cut this on a tablet. the servant is not named)
• cur | prev c. 1350 BC Akhenaten (talk | contribs) . . (2,080 bytes) (+90) . . (→ promoted to sole god of Egypt, all others deprecated. reverted immediately upon my death; see Egyptian cosmology for the arrangement that was restored)
• cur | prev c. 3000 BC everyone (talk | contribs) . . (1,990 bytes) (+200) . . (→ worshipped. the page has been the principal deity of nearly every civilisation to look up, which is not a claim the other articles here can make)
• cur | prev c. 1.5 Ga the solar cycle (talk | contribs) . . (1,790 bytes) (+70) . . (→ established a habit of flipping magnetic polarity every eleven years or so; spots to follow. the period is only approximately eleven and never has been exactly)
• cur | prev c. 3.8 Ga the faint young Sun (talk | contribs) . . (1,720 bytes) (+80) . . (note: I was some 30% dimmer then, which by the arithmetic should have left Earth frozen solid. it was not. this remains open on talk)
• cur | prev c. 4.5 Ga hydrostatic equilibrium (talk | contribs) . . (1,640 bytes) (+110) . . (→ gravity inward, pressure outward, balanced to within a hair for the foreseeable. no further structural edits anticipated for five billion years)
• cur | prev c. 4.56 Ga accretion (talk | contribs) . . (1,530 bytes) (+60) m . . (→ the debris in the disc has clumped into eight planets and assorted rubble, together amounting to 0.14% of the page. forked as Earth and others)
• cur | prev c. 4.57 Ga the T Tauri wind (talk | contribs) . . (1,470 bytes) (−70) . . (rm the remaining nebular gas – blew the leftovers clear of the page. anything not yet condensed is gone and will not be restored)
• cur | prev c. 4.57 Ga the core (talk | contribs) . . (1,540 bytes) (+400) . . (→ ignition. hydrogen commenced fusing to helium at some fifteen million kelvin; the page now generates its own light and requires no external source)
• cur | prev c. 4.6 Ga gravity (talk | contribs) . . (1,140 bytes) (+240) . . (→ collapse: the fragment contracted, spun up, and flattened to a disc. all subsequent content is drawn from this revision)
• cur | prev c. 4.6 Ga a molecular cloud (talk | contribs) . . (900 bytes) (+900) . . (created page; a fragment of cold gas some light-years across began, for reasons still under discussion, to fall in on itself)

Older revisions exist but have not been located. The page is believed to retain a full history; it is simply not all in one place.
