How to destroy the Earth

Preamble

Destroying the Earth is harder than you may have been led to believe.

You've seen the action movies where the bad guy threatens to destroy the Earth. You've heard people on the news claiming that the next nuclear war or cutting down rainforests or persisting in releasing hideous quantities of pollution into the atmosphere threatens to end the world.

Fools.

The Earth is a 4,550,000,000-year-old, 5,973,600,000,000,000,000,000-tonne ball of iron. It was built to last. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and lo, it still orbits merrily. So my first piece of advice to you, dear would-be Earth-destroyer, is: do NOT think this will be easy.

This is not a guide for wusses whose aim is merely to wipe out humanity. I can in no way guarantee the complete extinction of the human race via any of these methods, real or imaginary. Humanity is wily and resourceful, and many of the methods outlined below will take many years to even become available, let alone implement, by which time mankind may well have spread to other planets; indeed, other star systems. If total human genocide is your ultimate goal, you are reading the wrong document. There are far more efficient ways of doing this, many which are available and feasible RIGHT NOW.

Nor is this a guide for those wanting to annihilate everything from single-celled life upwards, render Earth uninhabitable or simply conquer it. These are trivial goals in comparison.

This is a guide for those who do not want the Earth to be there anymore.

Mission statement

For the purposes of what I hope to be a technically and scientifically accurate document, I will define our goal thus: by any means necessary, to render the Earth into a form in which it may no longer be considered a planet. Such forms include, but are most definitely not limited to: two or more planets; any number of smaller asteroids; a quantum singularity; a dust cloud.

Methods for destroying the Earth

Methods are ranked in order of feasibility.

Total existance failure

You will need: nothing

Method: No method. Simply sit back and twiddle your thumbs as, completely by chance, all 200,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 atoms making up the planet Earth suddenly, simultaneously and spontaneously cease to exist. Note: the odds against this actually ever occuring are considerably greater than a googolplex (1010100) to one. Failing this, some kind of arcane (read: scientifically laughable) probability-manipulation device may be employed.

Current feasibility rating: 0/10. Utter, utter rubbish.

Existence negated via time travel

You will need: a time machine, heavy rock-moving equipment/explosives

Method: Using your time machine, travel back in time just over 4,500,000,000 years to shortly (i.e. a few billenia) before the formation of the Earth. What you should find in its place is a young Sun and an accretion disc formed of the dusty/rocky material that will later become our Solar System. Find the patch of material that is likely to condense into the Earth. Now blow up, split apart and otherwise stir up the material so that it never gets a chance to come together and form the Earth. Return forwards in time in several hundred-million-year jumps, repeating the process each time so that no planet of any kind ever forms at roughly 1 AU from the Sun. If you make an error, simply go back in time and try again.

Earth's final resting place: When you finally return to the present day, you will be left with a largish asteroid belt where Earth should be. Alternatively, you may find that the matter has been assimilated into the bodies of other planets or the Sun.

Current feasibility rating: 0/10. Nonsense.

Comments: My good friend Rob rightly informs me that this course of action does not strictly speaking "destroy" the Earth - there is no actual destruction event in which the Earth goes from existing to not existing. What one ends up with instead is a universe in which the Earth does not and never did exist.

Destroying Rob proved remarkably easy.

Gobbled up by strangelets

You will need: a stable strangelet

Method: Hijack control of the Relativistic Heavy Ion Collider in Brookhaven National Laboratory, Long Island, New York. Use the RHIC to create and maintain a stable strangelet. Keep it stable for as long as it takes to absorb the entire Earth into a mass of strange quarks. Keeping the strangelet stable is incredibly difficult once it has absorbed the stabilising machinery, but creative solutions may be possible.

Earth's final resting place: a huge glob of strange matter.

Feasibility rating (revised): 1/10. A while back, there was some media hoo-hah about the possibility of this actually happening at the RHIC, but in actuality the chances of a stable strangelet forming are pretty much zero.

Sucked into a microscopic black hole

You will need: a microscopic black hole having enough mass not to evaporate instantly (thanks, Cletus the Fetus). Creating a microscopic black hole is tricky, since one needs a reasonable amount of neutronium, but may possibly be achievable by jamming large numbers of atomic nuclei together until they stick. This is left as an exercise to the reader.

Method: simply place your black hole on the surface of the Earth and wait. It will eat its way into the ground until it reaches the centre of the Earth, at which point it will sit and consume matter until the whole Earth is gone.

Earth's final resting place: roughly one cubic centimetre of neutronium a singularity of zero size (thanks cakedamber), which will then proceed to happily orbit the Sun as normal.

Feasibility rating: 2/10. Highly unlikely.

Source: Dark Side of the Sun, by Terry Pratchett. Starrynight and DejaMorgana have both cited earlier examples in science fiction, and though it is true that the microscopic black hole idea is an age-old science fiction mainstay which predates Pratchett by a long time, he was my original source for the idea, so that's what I'm putting.

Destroyed by a long-duration gamma ray burst/hypernova

You will need: a star in Earth's stellar neighbourhood with >40 solar masses. Such massive stars are hard to come by; even Betelgeuse has only 20 solar masses. The best candidate I know of is Eta Carinae, which has over 120 solar masses but is ~7500 light years away.

Method: Gamma ray bursts are powerful, short-lived floods of gamma ray photons. GRBs come in two flavours, short (less than 2 seconds) and long (2 seconds to about 3 minutes); the latter are believed to be caused by stellar explosions called hypernovae, hundreds of times more violent than ordinary supernovae. Such stars are usually billions of light years away when they explode - the fact that we can detect them at this range should tell you enough about how powerful a hypernova is. So how about triggering one locally? Any such explosion within about 20 light years would probably be violent enough to destroy the Earth itself.

Feasibility rating: 2/10. Way beyond our technological reach and likely to remain so indefinitely.

Sources: Lycurgus suggested this method. Further information from nasa.gov.

Engulfed in supernova

You will need: neutrinos? Or possibly some means of inhibiting nuclear fusion reactions. (Thank you, jasmine.)

Method: Simply cause the Sun to suddenly halt all its nuclear fusion reactions, thereby collapsing and then exploding with enough energy to momentarily outshine the entire rest of the galaxy. This one's actually pretty tricky, since as yet there is no scientific theory which could allow you to induce the Sun to go supernova. However, it does promise to be one of the most efficient and spectacular ways to destroy the Earth, so if you have the necessary skills and machinery, then I would recommend this over most other methods.

Earth's final resting place: a smear of vaporized iron moving across the universe at roughly 5% of the speed of light.

Feasibility rating: 2/10. Highly unlikely. Relies on as-yet undiscovered scientific theories.

Sucked into a giant black hole

You will need: a black hole, extremely powerful rocket engines, and, optionally, a large rocky planetary body. The nearest black hole to our planet is 1600 light years from Earth in the direction of Sagittarius, orbiting V4641.


Method: after locating your black hole, you need to move it as close to Earth as possible. This is likely to be the most time-consuming part of this plan. There are two methods, moving Earth or moving the black hole. Moving the Earth is simply a case of building three or four upward-pointing rocket engines (possibly nuclear? and each roughly the size of Switzerland) and firing them at strategic moments to steer it onto a collision course with your black hole of choice. Moving the black hole requires rather more skill since it is impossible to physically touch it and survive. For this you need to build your rockets on a completely different planet and push this in front of the black hole, towing it along in a carrot-and-donkey fashion. If time is short, you can consider moving both the Earth AND the black hole simultaneously.

Earth's final resting place: a nondescript cubic centimetre of neutronium in the heart of the part of the mass of the black hole (thanks, cakedamber).

Feasibility rating: 4/10. Way beyond our technological reach.

Earliest feasible completion date: I do not expect the necessary technology to be available until AD 3000, and add at least 1600 years for travel time.

Blown up by matter/antimatter reaction

You will need: twelve kilograms of antimatter, magnetic confinement chambers, a very deep hole in the ground. Antimatter - the most explosive substance possible - can be manufactured in small quantities using any large particle accelerator, but this may take some time to produce the required amounts. If you can create the appropriate machinery, it may be possible simply to "flip" 12kg of matter through a fourth dimension, turning it all to antimatter at once.

Method: Choose a good spot. Drill a mine shaft all the way to the centre of the Earth (6,371km down). This is the minimum guaranteed effective depth for your antimatter planetbuster bomb, but roughly 3000km should be sufficient for near-total disintegration. While drilling, manufacture 12 kilograms of antimatter and store it in magnetic confinement chambers for detonation. Place the antimatter at the bottom of the shaft, and switch off the confinement chambers. The resulting release of energy (obeying Einstein's famous mass-energy equation, E=mc2) should be sufficient to, at the very least, split the Earth into a thousand pieces.

UPDATE! Instead of going to all the trouble of constructing and maintaining a 3000km mineshaft (bearing in mind that the deepest such shaft built to date is a mere 3000-odd metres), consider loading your antimatter onto a self-contained drilling machine, perhaps powered by geothermal energy. This could burrow its way all the way to the core of Earth without you having to worry about keeping the passage behind it open. Note, however, that communicating a "detonate" command through a half-planet of molten iron is easily as difficult a task as manufacturing the antimatter in the first place. Timed or depth-triggered devices, on the other hand, are prone to failure.

Earth's final resting place: A second asteroid belt around the Sun.

Comments: Rubyflame informs me that 12 kg of antimatter would be nowhere near enough, and the appropriate calculations suggest that one would actually require somewhere in the region of a billion tonnes. In this case, four-dimensionally flipping an appropriately sized rock could prove to be the only surefire method. I should've known that it was never that easy. Thanks, Rubyflame.

trembling says I still think that antimatter is crazy s**t, i.e. wouldn't want it on my flapjacks

Feasibility rating: 5/10. Just about slightly possible.

Earliest feasible completion date: AD 2500. Of course, if it does prove possible to manufacture antimatter in the sufficiently large quantities you require - which is not necessarily the case - then smaller antimatter bombs will be around long before then.

Hurled into the Sun

You will need: a very large meteor indeed (say half the size of the Moon, or actually the Moon would do), some method of steering it

Method: Collision with any kind of meteor is unlikely to do any more damage to the Earth than carving a chunk out of it, rendering it uninhabitable, and knocking it out of its orbit. However, if you do your maths right, knocking it out of its orbit may be enough. Sending Earth on a collision course with the Sun is not as easy as one might think; it's surprisingly easy to end up with Earth in a loopy elliptical orbit which merely roasts it for four months in every eight, but with skill and backspin it can be done. Attach whatever rockets are necessary to a rocky body which is sufficiently far from the Earth. Swivel the body to face in the correct direction, and fire the rockets for a good long burn so that you build up a good speed. Note: more important than high speed is precision. Some knowledge of billiards may be useful.

Earth's final resting place: a small globule of vaporized iron sinking slowly into the heart of the Sun.

Feasibility rating: 6/10. Impossible at our current technological level, but may happen by freak accident.

Earliest feasible completion date: Via act of God: 2028 - any earlier and we'd have already spotted the asteroid in question. Via human intervention: given the current level of expansion of space technology, 2250 at best.

Eaten by von Neumann machines

You will need: a single von Neumann machine

Method: A von Neumann machine is any device that is capable of creating an exact copy of itself given nothing but the necessary raw materials. Create one of these that subsists almost entirely on iron, magnesium, aluminium and silicon, the major elements found in Earth's mantle and core. It doesn't matter how big it is as long as it can reproduce itself exactly in any period of time. I suggest exploring the possibilities of using geothermal energy as a power source. Release it into the ground under the Earth's crust and allow it to fend for itself. Watch and wait as it creates a second von Neumann machine, then they create two more, then they create four more. As the population of machines doubles repeatedly, the planet Earth will, terrifyingly soon, be entirely eaten up and turned into a swarm of as many as at least six trillion trillion machines. Technically your objective would now be complete - no more Earth - but if you want to be thorough then you can command your VNMs to hurl themselves, along with any remaining trace elements, into the Sun. This hurling would have to be achieved using rocket propulsion of some sort - thanks, C-Dawg - so be sure to include this in your design.

Earth's final resting place: the bodies of the VNMs themselves, then a small lump of iron sinking into the Sun.

Comments: randombit suggests that nanobots, as opposed to macroscopic VNMs, are the way to go. They consume raw materials and build new nanobots and/or nanoassemblers. "I suppose a giant killer robot that built more copies would work to, but doing it at the molecular level seems easer." Good thinking, randombit!

Feasibility rating: 7/10. So crazy it might just work.

Earliest feasible completion date: Potentially 2045-2050, or even earlier.

Meticulously and systematically deconstructed

You will need: a powerful mass driver, or ideally lots of them; ready access to roughly 1026J

Method: Basically, what we're going to do here is dig up the Earth, a big chunk at a time, and boost the whole lot of it into orbit. Yes. All six septillion tonnes of it. A mass driver is a sort of oversized electromagnetic railgun, which was once proposed as a way of getting mined materials back from the Moon to Earth - basically, you just load it into the driver and fire it upwards in roughly the right direction. We'd use a particularly powerful model - big enough to hit escape velocity of 11 kilometres per second even after atmospheric considerations - and launch it all into the Sun or randomly into space.

Alternate methods for boosting the material into space include loading the extracted material into space shuttles or taking it up via space elevator. All these methods, however, require a - let me emphasize this - titanic quantity of energy to carry out. Building a Dyson sphere ain't gonna cut it here. (Note: Actually, it would. But if you have the technology to build a Dyson sphere, why are you reading this?) See below for a possible solution.

Earth's final resting place: Many tiny pieces, some dropped into the Sun, the remainder scattered across the rest of the Solar System.

Feasibility rating: 8/10. If we wanted to and were willing to devote resources to it, we could start this process RIGHT NOW. Indeed, what with all the gunk left in orbit, on the Moon and heading out into space, we already have done.

Earliest feasible completion date: Ah. Yes. At a billion tonnes of mass driven out of the Earth's gravity well per second: 189,000,000 years.

Source: this method arose when JoeBaldwin and I knocked our heads together by accident.

Destroyed by vacuum energy detonation

You will need: a light bulb

Method: This is a fun one. Contemporary scientific theories tell us that what we may see as vacuum is only vacuum on average, and actually thriving with vast amounts of particles and antiparticles constantly appearing and then annihilating each other. It also suggests that the volume of space enclosed by a light bulb contains enough vacuum energy to boil every ocean in the world. Therefore, vacuum energy could prove to be the most abundant energy source of any kind. Which is where you come in. All you need to do is figure out how to extract this energy and harness it in some kind of power plant - this can easily be done without arousing too much suspicion - then surreptitiously allow the reaction to run out of control. The resulting release of energy would easily be enough to annihilate all of planet Earth and probably the Sun too.

Earth's final resting place: a rapidly expanding cloud of particles of varying size.

Comments: unperson's quantum field theory courses suggest that the quantity of vacuum energy available from zero point fluctuations in this method would actually be infinite. Ironically, though this doesn't invalidate the theory, it doesn't sound nearly as impressive... thanks, unperson.

Feasibility rating: 9/10. Worryingly plausible.

Earliest feasible completion date: 2060 or so.

Swallowed up as the Sun enters red giant stage

You will need: patience

Method: Simply wait for roughly 5,000,000,000 years. During its natural progress along the Main Sequence, the Sun will exhaust its initial reserves of hydrogen fuel and expand into a red giant star - swallowing up Mercury, Venus, Earth and Mars in the process. This is your basic fall-back method if all of the above fail.

Earth's final resting place: Again, boiling red iron in the heart of the Sun.

Comments: Rob, before he expired, also told me that this method is also semantically inaccurate, since you are not the one who destroys or causes the destruction of the Earth. Hey, whatever works.

Feasibility rating: 10/10. Guaranteed to work.

Earliest feasible completion date: AD 5,000,000,000

Natural decay

You will need: all-surpassing patience

Method: If by some insane chance, the expansion of the Sun into its Red Giant stage does not destroy the Earth (perhaps somebody moved the Earth out of the way in time), then there's still no need to fret. Protons, while incredibly stable, eventually decay like any other particle. Simply wait for a period of time of the order of 1,000,000,000,000,000,000,000,000,000,000,000,000 years, and roughly half of the constituent particles of Earth will have decayed into positrons and pions. If that's still too much like a planet for you, you could wait for another 1036 years, leaving only a quarter of the original Earth. Or wait even longer. Eventually there will be as little of Earth left as you wish.

Earth's final resting place: Miscellaneous positrons and gamma radiation (pions decay almost instantly into gamma ray photons) scattered thinly across the entire universe.

Feasibility rating: 10/10. Absolutely guaranteed to work: essentially unstoppable.

Earliest feasible completion date: AD 1,000,000,000,000,000,000,000,000,000,000,000,000

Reduced to subatomic dust

You will need: a weak strong nuclear force destabilizer

SNFDs are completely outside the range of modern science, but the method sounds vaguely plausible, so here it is. The strong nuclear force is what holds molecules atomic nuclei together and, for example, stops people from flying apart into clouds of free quarks. Simply aim your SNFD at Earth and fire, or activate it while on the ground, or however your model works (design may vary). Congratulations. The Earth is now an expanding cloud of dust.

Earth's final resting place: a cloud of randomized subatomic matter.

Things which will NOT destroy the Earth

Armageddon, as described in the Bible. Fieari says Armageddon does not destroy the Earth, nor even everyone on it. One third of the human population is wiped out repeatedly (at least one third of one third) but then not only does the remnant survive, but God's people return from heaven and get to live in a city roughly the size of half the planet. This is as far from your definition of "destroying the Earth" as you can reasonably get, as the planet is still there AND people still live on it. Thanks, Fieari!

Paradoxes as described in Back To The Future Part II. By definition, a paradox cannot actually come into existence.

Ceasing all thought (if the Earth is not observed, then how can it exist?). Philip K. Dick said it best: "Reality is that which, when you stop believing in it, doesn't go away."

Detonating all the nuclear weapons ever created simultaneously, either all at one location or strategically placed around the globe. This will irradiate pretty much the entire globe and cause a nuclear winter but will actually destroy very little of the planet itself.

Proving that 1=0. If one did indeed equal zero, so it is reasoned, then since is one Earth, there must be zero Earths... so, if one could prove it, the Earth would cease to exist. This is specious logic. Finding a proof in mathematics does not magically change a fact from being false to being true. It merely verifies rigorously as true a fact that always was true. Thus, if 1=0 could be proved, then it would always have been true and the Earth should never have existed. But Earth is still here. QED.

General advice

In addition to the equipment listed above, and regardless of choice of method, you will of course need several more things: support, money, planning and brains. Not necessarily all of them, though. Sufficiently dedicated supporters can provide you with money (though not necessarily brains). Brains will enable you to do your own planning and earn or steal the money for yourself. And money can of course hire supporters, planners and scientists to work for you. Probably the most important of these is planning, because planning will enable you to pick up the slack when your supporters, creditors and scientific advisors threaten to desert you.

What subjects should I study if I want to destroy the Earth? Though not necessarily essential, a working knowledge of the method you're intending to use to destroy the Earth is useful. For this you'd be advised to pursue mainly sciences, with the main emphasis on physics (quantum, atomic, and astrophysics in particular), but also some electronic and mechanical engineering, mathematics and possibly robotics. But you can pay other people to think for you; your time might be better invested studying finance and economics, and brushing up your management, speaking and people skills, powers of persuasion, and charisma. Charisma is definitely a big one.

How about careers? Again, working in the sciences will provide you with lots of useful know-how when the time comes to destroy the Earth, but unless the method you select can pulled off with equipment lying around in your lab (which is not impossible - see the Strangelet and Von Neumann Machine methods respectively), you may find yourself powerless to put your plan into action. Instead, you need to seek a position of power - join a big company (perhaps ICI, NASA, Boeing, or a bank) and work your way up to CEO. This will provide you with lots of useful resources which you can use to put your plan into action. Politics and the armed forces are also great possibilities.

Assuming, of course, that you and whatever trusted advisors you have allowed to side with you do not intend to "go down with the ship", it is advisable to make plans for alternate living arrangements before you embark on a course of action which may result in the destruction of the Earth. Since in most cases the hypertechnology required to actually destroy the Earth is ridiculously advanced, access to an interstellar spacecraft, a space station or another habitable planet is likely to be well within your grasp, but please, plan ahead.

Stand at a safe distance. Lurking at least one AU out of range of whatever terrible destructive force you are about to unleash is strongly recommended in most cases, but for the supernova particularly you'll want to put as much as a thousand light years between yourself and the Earth when it happens.

If you have to be physically on Earth to begin the destruction process (e.g. von Neumann machines, antimatter blast), then set a countdown of at least a week. Make sure the countdown timer is a) thoroughly tested and b) tamper-proof. The same goes for your escape route.

If the method you choose can be tried more than once (e.g. hurled into Sun, vacuum energy detonation), and your budget will stretch, you could consider practicing on smaller astronomical bodies and working your way up. For example, consider destroying Mercury, or Ceres. Don't forget to take notes on what went particularly well, what didn't work, what was unnecessary, etc., just so everything goes as smoothly as possible on the big day.

Take a camera. Most of the methods listed above are incredibly spectacular and witnessing them will probably be once-in-a-lifetime opportunity for you, so remember to capture the moment.

If you do fail, don't give up! Remember, nobody has ever successfully destroyed the Earth.

If the Earth's major governing body or bodies get wind of your plans ahead of time, they may well try to interfere with the scheme or even avert it. You should try to keep your plot to destroy the Earth as secret as possible, or at least provide yourself with a means of defence/escape in case someone does try to intervene. Alternatively, consider taking the relatively trivial precaution of wiping out the population of the Earth beforehand. See also The Evil Overlord list for lots more general advice on these topics.
