Just For Fun / Apocalypse Day Planner

Go To
Aw man, I missed it.
"But about that day and hour no one knows, not even the angels of heaven nor the Son, but only the Father."
Matthew 24:36, The Bible (New International Version), disavowing the contents of this very page.

Writers are fond of putting precise dates on the Apocalypse. There's really nothing more dramatic than The End of the World as We Know It, but claiming that it will occur just 20 Minutes into the Future isn't quite as dramatic as saying it will occur in precisely Six Years, Eight Months, Seven Days ... and counting.

So one might propose that if all the movies, Video Games and other media depicting the world's destruction were correct, we'd be seeing the world ending at least once a week, and especially on dates that appear numerically significant.

Related to I Want My Jetpack (though in all seriousness, sometimes not even villains want an Earth-Shattering Kaboom).

For more information on fictional world history, see Grand Unified Timeline and The Movie Timeline. And for information about non-fictional predictions, Wikipedia has their own list, too. Rational Wiki also has a list where many recent crank predictions can be found.

Of course, the real problem with this page is... if it happens, most of us will be destroyed anyway.

Unmarked spoilers here! You've been warned!

The Earth has already been destroyed on:

  • Circa 250,000,000 BC: Permian-Triassic Extinction (AKA, the Great Dying). Killed 90-95% of all life at the time.

  • 5 Jul 1998: According to The Church Of The Subgenius, this is "X-Day", when alien invaders will destroy all the "normals" while church members will be rescued by "alien sex goddesses".

Seen from the row seats at the Milliways restaurant (and remember to open a bank account and put on it a penny, letting accruing interests to pile up as years go by so you can pay for the admission).

People in Real Life think the Earth has been/will be destroyed on:

  • ca. 2800 BCE: Supposedly, an Assyrian clay tablet dating to approximately 2800 BC was unearthed bearing the words "Our earth is degenerate in these latter days. There are signs that the world is speedily coming to an end. Bribery and corruption are common."
  • Somewhere between 30 - 100AD: early Christians believed that the end of the world would happen within their lifetime, due to a "cryptic" statement from Jesus that his followers would "not taste death" before the second coming of Christ.
  • 1033 AD Many Christians of the time believed that Christ would come 1000 years after his death (even though this is probably not even the right year for that).
  • 21 Mar 1843: Millerite Christians believed the world would end this date. Later amended to 21 Mar 1844, 18 Apr 1844 and 22 Oct 1844. See The Great Disappointment.
  • 1881: 16th century prophetess Mother Shipton supposed predicted that, "The world to an end shall come, In eighteen hundred and eighty one." Actually, this poem wasn't written by Mother Shipton at all. It was a hoax invented by Charles Hindley in 1862.
  • 1910: The appearance of Halley's Comet. Irresponsible newspapers played up the recent discovery that comet tails contained poison and created a panic. Gullible people bought gas masks, "anti-comet pills", and "anti-comet umbrellas".
  • 1914: Jehovah's Witnesses think the world started ending this year.
  • June-July 1945: At the Trinity test site, some of the researchers harbored worries that the detonation of the Trinity device could ignite the entire atmosphere of the Earth. On the up side, that would have put an end to World War II...
  • October 14 - 28, 1962: The period of the Cuban Missile Crisis, which people believed was the start of World War III, and as such, the beginning of the end of humanity as they knew it.
  • 1975: It was never official doctrine, but many Jehovah's Witnesses believed the world would end in this year, having calculated it was exactly 6,000 years after Adam's creation. It was rather a case of enthusiasm beats sense, containing several logical errors even within the framework of Jehovah's Witness belief. For instance, Adam was given a large project to do before Eve was even created.
    • Jossed: The basis for the calculation (the idea that the creative days have fixed length) was later dropped.
  • September 6, 1994: Some Christians predicted this was the date, but after it came and went it was changed to May 21, 2011. See Below.
  • August 11, 1999, as predicted by Nostradamus.
  • 01 Jan 2000: Experts predicted anything from mild inconvenience to the collapse of society as the Y2K bug (allegedly) crippled computers worldwide by confusing the year 1900 with the year 2000. This was also a popular day for apocalyptic cults to think the world would end.
  • May 5, 2000: According to the 1994 telecast of Ancient Prophecies, the Great Pyramid predicted the end of the world on this date.
  • 06 Jun 2006: Also a popular date for cults to think the world would end.
  • January 19-20, 2008: A small group of people on the GameFAQs' Paranormal/Conspiracy Board believed that a giant meteor was going to destroy Earth on either the 19th or 20th. Considering the source it's not all too surprising that we lived to see the 21st.
  • May 21, 2011: According to the surprisingly large "Family Radio" organization of Christians, this date is when the world ends...
  • 21 Dec 2012: The Mayan calendar ends, and some believe the world will end, even if the Mayans themselves didn't.
    • And of course, the Mayans didn't. The calendar event coming in 2012 has happened several times throughout history. It's rare, but it's more like what the beginning of the millennium was to us than the end of their calendar.
    • Jossed.
  • 23 September 2015: Another date that circulated the internet briefly. Unsurprisingly, the world didn't end then either.
  • 23 September 2017: See above, mostly Nibiru-related claims for this one.
  • 2029: Potential impact by the asteroid Apophis. Later ruled out by additional calculations.
  • 2036: If Apophis misses, this is when it swings around for a second shot. Later ruled out by additional calculations.
  • 19 Jan 2038: Experts predict anything from mild inconvenience to the collapse of society as Y2K's big brother steps in and resets all clocks based on 32-bit UNIX timestamps to -2147483648 (which corresponds to December 13, 1901)).
  • 2807 or 11,103: In 1983, astrophysicist Brandon Carter proposed that that human race had a 95% chance of extinction in 9,120 years, based on probabilistic reasoning now codified as the Doomsday Argument. The blog What If? further uses the same argument to suggest that, if one assumes the world's population reaches 9 billion and holds there until the estimated 2.2 trillion humans through all of history are accumulated (Carter's calculation estimated a total timeless human population of 1.2 trillion), there's about a 50/50 chance the last humans will live around the 29th Century (What If's 95% chance threshold is around 16,000 years). Your estimates may vary depending on assumptions made about things like how many humans have ever lived in the past, the distribution of those humans' lives (there are seven times as many humans alive today than just two centuries ago)note , human life expectancy now and in the future, and how reasonable you find taking past patterns and applying it to the future (e.g., we're less than 70 years into an age where nuclear Mutually Assured Destruction became a thing).
  • in 100,000 years: When the next ice age is supposed to arrive at its earliest, once anthropogenic global warming finally wears out.
  • in 1 billion years: Temperatures on Earth become too hot to support complex life. Only bacteria and the like will remain.
  • in 2.8 billion years (if not before): Earth becomes too hot to support even simple life.
  • in 7.5 billion years: When the Sun is expected to turn into a red giant (5 billion years to exhaust its central hydrogen supply plus 2.5 billion years to reach full red giant status), possibly engulfing Earth in the process, before finally becoming a white dwarf and fading away.
  • in 50 billion years: If the universe is a closed universe i.e. the 3-D space that our universe occupies curves back in on itself forming an ellipsoid boundary, and the universe’s expansion due to dark energy maintains its current rate of increase of acceleration (acceleration increases with time), then The Big Rip will occur in 50 billion years. The Big Rip will at first shatter space time into pockets, then everything in those pockets will get ripped apart into atoms, then atoms rip apart, then nucleons rip apart and finally all that will be left are fundamental particles, assuming that even space-time itself was not torn apart. However, most astrophysicists don’t believe that the universe is a bounded closed universe. An alternative without runaway dark energy is that it became attractive causing the Universe to collapse on itself in a Big Crunch, going back to the original singularity and maybe "rebooting" in a new Big Bang.
  • in 180 billion years: When the white dwarf remains of the Sun stop glowing. This assumes Earth's orbit has been adjusted to keep it in the habitable zone throughout the Sun's expansion into a red giant and subsequent shrinkage into a white dwarf. The proposed orbital adjustment method is repeated gravitational slingshot of loose material in the Solar system. It has been calculated that there is enough loose material. By far the least realistic point of this proposal is the requirement for a civilisation to last long enough, and provide funding consistently enough, for the multiple-millenia periods of throwing rocks around to adjust Earth's orbitnote .
  • in 292 billion years: If there're still 64-bit Unix systems (or their alien equivalents) running by then, and the Universe still exists, in the year 292,277,026,596 clocks will reset producing an equivalent of the already described Year 2038 problem.
  • in one hundred trillion (1 followed by 14 zeros) years: All stars, even their cooling corpses (white dwarfs, etc), are expected to have burned out plunging the Universe into darkness. Collisions between brown dwarfsnote  or dead stars may produce from new stars to supernovae or gamma-ray bursts for a long time to come, but they'll be extremely few and far between.
  • in a quattordecillion (1 followed by 45 zeros) years: If the standard model of proton decay is correct, then the Earth, humans, stars, planets and pretty much all elements we are so familiar with, cannot physically exist any more because protons will not exist anymore. So, anything that isn’t already singularities (Black holes) —white dwarves and neutron stars being composed of protons and neutrons are not inmune to this, even if will have decayed into at the very least, mesons.

May Happen At Any Moment:

  • Left Behind tells us the rapture will happen "tomorrow" and it's pretty much all downhill from there for a good seven years, but as we all know, tomorrow never comes!
  • Australia, at least according to Mad Max will be taken out "A Few Years From Now."
  • Azathoth could destroy the world at any moment, and wouldn't even notice. Bummer.
  • A Supervolcano blows up, most likely in Yellowstone. Best case scenario would be the destruction of most of western North America. That's the best case scenario.
    • Worst case scenario? The whole world dies from volcanic ash. Ouch.
  • Despite the introduction of nuclear weapons non-proliferation treaties (say that five times fast), enough live/active nuclear weapons still exist to wipe out the entire human race, depending on when they're dropped. We just can't take them apart as fast as we made them.
  • A massive solar storm hits us with a huge mass of charged particles, which interact with the Earth's magnetic field, sending huge currents along high voltage power cables, saturating transformer cores and melting them... all across the globe. Repairs could take months, during which access to food and water becomes a problem since so much of the developed world's infrastructure depends on electricity. The USA might even become a third-world country.
  • The technological singularity, where artificial intelligence will be created that's smarter than humans and build machines even more intelligent than themselves. Thus, such machines could easily overpower humanity with superior smarts. Most scholars who study this singularity predict it will happen sometime within this century, and all of them say it can suddenly happen any moment. More than a few even believe it will happen this generation of people. In other words, be ready for The Second Renaissance.
  • Iji: An alien race known as Tasen Alpha Strike the Earth, annihilating most of the life there.
  • False Vacuum Decay. Would destroy the entire universe at light speed. (And this is just one example from the Wonderful Wacky World of Quantum Physics.)

May ALREADY have happened:

  • Scientists trying to discover what 'time' actually is, have come up with a number of theories, one of which is that at any moment time could just stop, and the entire universe will be stuck in one final moment for eternity.
  • According to astronomers, the binary star WR 104's rotational axis is aimed in Earth's general direction (between 16° and 40°) and is capable of firing a gamma ray burst. Thing is, WR 104 is 8000 lightyears away which means the state we see the star in is the state it was in 8000 years ago. Due to gamma ray bursts moving at light speed, the star may have already gone supernova and fired one off - and we'd have zero advance warning until the gamma ray burst actually hits us. Just a ten second long burst would irradiate the hemisphere facing the star and blow away a full quarter of the ozone layer, leaving those surviving open for even more cosmic radiation. And if that still wouldn't be enough, it could also screw around with the chemical composition of the atmosphere to create nitrogen-dioxide and plunge the planet into a nuclear winternote 
  • If you're any species on Earth other than H. sapiens, odds are good that this trope began for you the moment that the human species started lighting brushfires and planting seeds in the ashes. Biologists consider our own era to be the latest of the Great Mass Extinctions.
