читать дальшеMethods for destroying the Earth
To be listed here, a method must actually work. That is, according to current scientific understanding, it must be possible for the Earth to actually be destroyed by this method, however improbable or impractical it may be.
Methods are ranked in order of feasibility.
Several methods involve moving the Earth a considerable distance off its usual orbital track. This is an essay in itself, so a separate page has been created for it.
Fissioned
You will need: a universal fission machine (e.g. a particle accelerator), an unimaginable amount of energy
Method: Take every single atom on planet Earth and individually split each one down to become hydrogen and helium. Fissioning heavier elements to become hydrogen and helium is the opposite of the self-sustaining reaction that powers the Sun: it requires you to put energy in which is why the energy requirements here are so vast.
Earth's final resting place: While Jupiter, Saturn, Uranus and Neptune are gas giants composed primarily of hydrogen and helium, they are massive enough to actually hold on to their tenuous atmospheres. The Earth is not; the gases would dissipate away. You'd get a wispy mess of gas where there should have been a planet.
Feasibility rating: 2/10. Technically possible, but hopelessly, mind-bogglingly inefficient and time-consuming.
Earliest feasible completion date: You're looking at billions of years minimum, folks.

Sucked into a microscopic black hole
You will need: a microscopic black hole. (всего то! ))))
Note that black holes are not eternal, they evaporate due to Hawking radiation. For your average black hole this takes an unimaginable amount of time, but for really small ones it could happen almost instantaneously, as evaporation time is dependent on mass. Therefore your microscopic black hole must have greater than a certain threshold mass, roughly equal to the mass of Mount Everest.
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. Black holes are of such high density that they pass through ordinary matter like a stone through the air. The black hole will plummet through the ground, eating its way to the centre of the Earth and all the way through to the other side: then, it'll oscillate back, over and over like a matter-absorbing pendulum. Eventually it will come to rest at the core, having absorbed enough matter to slow it down. Then you just need to wait, while it sits and consumes matter until the whole Earth is gone.
Earth's final resting place: a singularity with a radius of about nine millimetres, which will then proceed to happily orbit the Sun as normal.
Feasibility rating: 3/10. Highly, highly unlikely. But not impossible.
Comments: Getting closer!

Blown up by matter/antimatter reaction
You will need: 1,300,000,000,000 tonnes of antimatter.
Antimatter - the most explosive substance possible - can be manufactured in small quantities using any large particle accelerator, but this will take some considerable time to produce the required amounts. If you can create the appropriate machinery, it may be possible - and much easier - simply to "flip" 1.3 trillion tonnes of matter through a fourth spacial dimension, turning it all to antimatter at once.
Method: This method involves detonating a bomb so big that it blasts the Earth to pieces.
This, to say the least, requires a big bomb. All the explosives mankind has ever created, nuclear or non-, gathered together and detonated simultaneously, would make a significant crater and wreck the planet's ecosystem, but barely scratch the surface of the planet. There is evidence that in the past, asteroids have hit the Earth with the explosive yield of five billion Hiroshima bombs - and such evidence is difficult to find. It is, in short, insanely difficult to significantly alter the Earth's structure with explosives. This is not to mention the gravity problem. Just because you blasted the Earth apart doesn't mean you blasted it apart for good. If you don't blast it hard enough, the pieces will fall back together again under mutual gravitational attraction, and Earth, like the liquid metal Terminator, will reform from its shattered shards. You have to blow the Earth up hard enough to overcome that attraction.
How hard is that?
If you do the lengthy calculations you find that to liberate that much energy requires the complete annihilation of around 1,246,400,000,000 tonnes of antimatter. That's assuming zero energy loss to heat and radiation, which is unlikely to be the case in reality: You'll probably need to up the dose by at least a factor of ten. Once you've generated your antimatter, probably in space, just launch it en masse towards Earth. The resulting release of energy (obeying Einstein's famous mass-energy equation, E=mc2) should be sufficient to split the Earth into a thousand pieces.
Greg Bear's novel, "The Forge Of God", contains an interesting refinement of this technique. Here, the antagonist instead generates antimatter in the form of a "slug" of anti-neutronium - superdense material massing a billion kilograms per cubic centimetre. This is fired into the Earth's core. Neutronium passes through ordinary matter as easily as a ball flies through the air, so the anti-neutronium slug doesn't annihilate immediately; rather, it builds up a protective sheath of plasma around it as it plunges downwards towards the Earth's core. It's then followed up by a slug of regular neutronium, which also falls into the core, at a time calculated to meet the first slug head-on at the exact centre of the Earth, where they annihilate themselves, and soon afterwards, the Earth itself. Highly space-efficient, and with the added bonus of all the energy being released at the Earth's core, where it can do the most damage. In the book, the antagonists simultaneously detonate nuclear warheads in certain oceanic trenches, to weaken the crust and allow the planet to be blown apart more easily.
Earth's final resting place: A second asteroid belt around the Sun.
Comments: trembling writes, "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.
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 get it and the Earth together. This is likely to be the most time-consuming part of this plan. There are two methods, moving Earth or moving the black hole, though for best results you'd most likely move both at once. See the Guide to moving Earth for details on how to move the Earth. Several of the methods listed can be applied to the black hole too, though obviously not all of them, since it is impossible to physically touch the black hole, let along build rockets on it.
Earth's final resting place: part of the mass of the black hole.
Feasibility rating: 6/10. Very difficult, but definitely possible.
Earliest feasible completion date: I do not expect the necessary technology to be available until AD 3000, and add at least 800 years for travel time. (That's in an external observer's frame of reference and assuming you move both the Earth and the black hole at the same time.)
Sources: The Hitch Hiker's Guide To The Galaxy, by Douglas Adams; space.com.
Comments: It's clear that dropping the Earth into a singularity is massive overkill. A reasonably strong gravitational field, such as might be associated with any body between Jupiter and a neutron star, would be sufficient to rip the Earth apart via tidal forces. These possibilities are dealt with further down.
Meticulously and systematically deconstructed
You will need: a mass driver. 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. Your design should be powerful enough to hit escape velocity of 11 kilometres per second.
One mass driver would suffice, but ideally, lots (i.e. trillions) would be employed simultaneously. Alternatively you could use space elevators or conventional rockets.
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 sextillion tonnes of it.
We will ignore atmospheric considerations. Compared with the extra energy needed to overcome air friction, it would be a relatively trivial step to completely burn away the Earth's atmosphere before beginning the process. Even with this done, however, this method would 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?)
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: 6/10. 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. Make sure you build LOTS of mass drivers.
Source: this method arose when Joe Baldwin and I knocked our heads together by accident.
Pulverized by impact with blunt instrument
You will need: a big heavy rock, something with a bit of a swing to it... perhaps Mars.
Method: Essentially, anything can be destroyed if you hit it hard enough. ANYTHING. The concept is simple: find a really, really big asteroid or planet, accelerate it up to some dazzling speed, and smash it into Earth, preferably head-on but whatever you can manage. The result: an absolutely spectacular collision, resulting hopefully in Earth (and, most likely, our "cue ball" too) being pulverized out of existence - smashed into any number of large pieces which if the collision is hard enough should have enough energy to overcome their mutual gravity and drift away forever, never to coagulate back into a planet again.
A brief analysis of the size of the object required can be found here. Falling at the minimal impact velocity of 11 kilometres per second and assuming zero energy loss to heat and other energy forms, the cue ball would have to have roughly 60% of the mass of the Earth. Mars, the next planet out, "weighs" in at about 11% of Earth's mass, while Venus, the next planet in and also the nearest to Earth, has about 81%. Assuming that we would fire our cue ball into Earth at much greater than 11km/s (I'm thinking more like 50km/s), either of these would make great possibilities.
Obviously a smaller rock would do the job, you just need to fire it faster. Taking mass dilation into account, a 5,000,000,000,000-tonne asteroid at 90% of light speed would do just as well. See the Guide to moving Earth for useful information on manoeuvring big hunks of rock across interplanetary distances.
Earth's final resting place: a variety of roughly Moon-sized chunks of rock, scattered haphazardly across the greater Solar System.
Feasibility rating: 7/10. Pretty plausible.
Earliest feasible completion date: AD 2500, maybe?
Source: This method suggested by Andy Kirkpatrick
Comments: Earth is believed to have been hit by an object the size of Mars at some point in the distant past before its surface cooled. This titanic collision resulted in... the Moon. You can download a simulated video of the impact from this page. While the Mars-sized object in question obviously didn't hit Earth nearly as hard as we're proposing with this method, this does serve as a proof of concept.
Many useful planetary facts can be found here.
Hurled into the Sun
You will need: Earthmoving equipment.
Method: Hurl the Earth into the Sun, where it will be rapidly melted and then vaporized by the Sun's heat.
Sending Earth on a collision course with the Sun is not as easy as one might think. Contrary to popular opinion, Earth's orbit is not "unstable" and Earth will not begin to spiral into the Sun if we give it the slightest of nudges (otherwise, you can bet it would have happened already). It's surprisingly easy to end up with Earth in a loopy elliptical orbit which merely roasts it for four months in every eight. Careful planning will be needed to avoid this.
Comments: As far as energy changes are concerned, this method is inferior to the next one.
Earth's final resting place: a small globule of vaporized iron sinking slowly into the heart of the Sun.
Feasibility rating: 9/10. Impossible at our current technological level, but will be possible one day, I'm certain. In the meantime, may happen by freak accident if something comes out of nowhere and randomly knocks Earth in precisely the right direction.
Earliest feasible completion date: Via act of God: 25 years' time. 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.
Source: Infinity Welcomes Careful Drivers, by Grant Naylor
Ripped apart by Jupiter
You will need: Earthmoving equipment.
Method: Hurl the Earth into Jupiter, where it will be torn apart by tidal forces.
Moving the Earth out to Jupiter is much the same as moving the Earth in towards the Sun, the most obvious difference being your choice of vectors. However, there is another important consideration, and that is energy. It takes energy to raise or lower an object through a gravity field; it would take energy to propel the Earth into the Sun and it would take energy to propel it into Jupiter. When you do the calculations, Jupiter is actually rather preferable; it takes about 38% less energy.
Earth's final resting place: lumps of heavy elements, torn apart, sinking into the massive cloud layers of Jupiter, never to be seen again.
Feasibility rating: 9/10. As before, impossible at our current technological level, but will be possible one day, and in the meantime, may happen by freak accident if something comes out of nowhere and randomly knocks Earth in precisely the right direction.
Earliest feasible completion date: As before, via act of God: 25 years' time. 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.

често говоря, сам фильм "Матрица" терпеть не могу, но издеваться над ним - всегда пожалуйста ))

23.03.2006 в 00:34Один из курсов, которые я веду - основы пластической анатомии. Скелет, группы поверхностных мышц, точки опоры, всё такое. Восприятие напрямую зависит от подачи. Я в своё время обзевалась, но нравилось ( и нравится
Работы прошлого курса у меня не сохранились, нынешний такого ещё не делал. Как только поработаем - покажу, не сомневайся, выглядит это и в самом деле очень забавно

Думаю, что можно идтив любую компанию, где требуются расчеты. Например, можно потом уйти изучать экономические тренды, то есть анализировать состояние фондового рынка и т.д. и т.п. анализируя графики

едиснтвенный истинный пейрингпервый номер в хит-параде фетишей )))Ух ты, звучит в высшей степени интересно ))) Интересные лекции - это всегда лучше, чем два часа безраздельной скуки и считания пролетающих мимо ворон. Через такие лекции думаю, что все проходят
массовый фанарт на профессиональной основе

25.03.2006 в 07:44правильно, все странное и непонятное надо уважать

может сами поймут? Или устрой им показательный зачет студентов. Хм, что-нибдуь в этом роде, чтобы доказать, что студенты предмет знают - а это самое главное
а почему через семестр? ))

26.03.2006 в 14:26Через семестр - п.ч. сейчас у меня люди только первый курс заканчивают, рано им ещё серьёзным присованием заниматься. Профанацию никто не уважает.
