Ten Ways to destroy Mother Earth

Posted by Sunny


Whether it took the Earth 4.5 billion years to get to where it is today (or a mere seven days), destroying it might take a lot less time. Take a look at these spell-bounding new ways of destroying our Earth and how far man can reach from today's perspective.

10. Total existence 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 occurring are considerably greater than a googolplex to one. Failing this, some kind of arcane (read: scientifically laughable) probability-manipulation device may be employed.

Utter, utter rubbish.


9. 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 stabilizing machinery, but creative solutions may be possible.

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.

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


8. Sucked into a microscopic black hole

You will need: a microscopic black hole. 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 you 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 center 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.

Highly, highly unlikely. But not impossible.

Earth's final resting place: a singularity of almost zero size, which will then proceed to happily orbit the Sun as normal.

Source: "The Dark Side Of The Sun," by Terry Pratchett. It is true that the microscopic black hole idea is an age-old science fiction mainstay which predates Pratchett by a long time.


7. Blown up by matter/antimatter reaction

You will need: 2,500,000,000,000 tons 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" 2.5 trillion tons of matter through a fourth dimension, turning it all to antimatter at once.

Method: This method involves detonating a bomb so big that it blasts the Earth to pieces.

How hard is that?

The gravitational binding energy of a planet of mass M and radius R is - if you do the lengthy calculations - given by the formula E=(3/5)GM^2/R. For Earth, that works out to roughly 224,000,000,000,000,000,000,000,000,000,000 Joules. The Sun takes nearly a WEEK to output that much energy. Think about THAT.

To liberate that much energy requires the complete annihilation of around 2,500,000,000,000 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=mc^2) should be sufficient to split the Earth into a thousand pieces.

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

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.


6. 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.

Slightly possible.

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

Earliest feasible completion date: 2060 or so.

5. 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.

Very difficult, but definitely possible.

Earth's final resting place: part of the mass of the black hole.

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.)

4. Meticulously and systematically deconstructed

You will need: a powerful mass driver, or ideally lots of them; ready access to roughly 2*10^32J

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 tons 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 kilometers 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 No. 6 for a possible solution.

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.

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

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


3. 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 kilometers 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. A 10,000,000,000,000-tonne asteroid at 90% of light speed would do just as well. See the Guide to moving Earth for useful information on maneuvering big hunks of rock across interplanetary distances.

Pretty plausible.

Earth's final resting place: a variety of roughly Moon-sized chunks of rock, scattered haphazardly across the greater Solar System.

Earliest feasible completion date: AD 2500, maybe?


2. 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, aluminum 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. 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 potentially sextillions of 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, so be sure to include this in your design.

So crazy it might just work.

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

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

Source: "2010: Odyssey Two," by Arthur C. Clarke


1.
Hurled into the Sun

You will need: Earthmoving equipment

Method: Hurl the Earth into the Sun. Sending Earth on a collision course with the Sun is not as easy as one might think; even though you don't actually have to literally hit the Sun (send the Earth near enough to the Sun (within the Roche limit), and tidal forces will tear it apart), 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 careful planning can avoid this.

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

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.

What's the worlds fastest supercomputer used for?

Posted by Sunny

The world's fastest supercomputer will probably never be known as the world's fastest supercomputer. RIKEN's MDGrape-3 is the first machine to break the petaflop barrier -- that's 1 quadrillion calculations (floating-point operations, to be specific) per second -- and it's three times faster than the currently ranked fastest computer in the world, IBM's BlueGene/L. But MDGrape-3 is so specialized that it can't run the software used to officially rank computing speed. What it can do is determine the effect of any chemical compound on one of the most intricate systems in the human body in a couple of seconds.


MDGrape-3 is designed for pharmaceutical research, specifically molecular dynamics simulation. In developing drugs, pharmaceutical companies have to analyze thousands on thousands of chemical compounds to find out how they'll affect the protein-bonding structures in the human body. Protein structures called enzymes are the building blocks that do all of the work within a cell, and the way these proteins bond with any drug compound introduced into the human body determines the body's response to that drug.

MDGrape-3 produces simulations of these molecular interactions. What takes most computers hours or days to analyze takes MDGrape-3 a few seconds. This functionality is invaluable in drug research, and it could drastically cut the research time involved in the development of new cures. A subsidiary of pharmaceutical giant Merck has already booked time on the machine.

Structurally speaking, MDGrape-3 is a parallel computing system consisting of two main sections: a primary server unit and a specialized-engines unit. The latter component is a cluster of 201 engines running proprietary chips developed by Riken specifically for MDGrape-3. It's this huge set of engines, running 24 MDGrape-3 chips each, that does the heavy protein-analysis lifting. Each chip has a maximum processing speed of 230 gigaflops (one billion operations per second).

The primary server unit manages the engine cluster. This parallel server setup runs two different types of processors: 65 servers run dual-core Intel 5000-series Xeon processors, 256 per server; and 37 servers run 3.3-GHz Intel Xeon processors, each with 2 MB of level 1 cache, at 74 processors per server. This hardware structure enables the 1-petaflop speed, which is the machine's theoretical maximum for certain processes.

MDGrape-3 took $9 million and about four years to build. And it's actually very efficient -- a total cost of $9 million breaks down to about $15 per gigaflop. The slower BlueGene/L cost about $140 per gigaflop to build.

BlueGene/L, which tops out at a theoretical 360 teraflops (trillion calculations per second), is also a biotechnology-specific machine. The advances in speed marked by these two supercomputers is indicative of a general trend in technology toward biologically-slanted systems. Some say the trend really started with the successful mapping of the human genome in 2000.

Regardless of what spurred the current biotechnology race, most experts agree that the logical end of the surge is a state of DNA-based medicine. In several decades, we could make an appointment with our doctor for a quick DNA analysis to find out what diseases we're at risk for and pop a single, gene-targeting pill that eliminates all of those foreseeable risks.

Super humans:steroids

Posted by RAJESH


Benjamin Sinclair "Ben" Johnson broke the world record in 100m sprint in olympics with a mind boggling timing of just 9.79 seconds..but later he was disqualified as he used steroids..
Barry bonds famous baseball player admitted he used steroids and ruined his carrer...
and there are many superheroes whoz names cannot be revealed who have used steroids...
This image is not a work of graphics its the magic of steroids..
lets know how this super heroes are made..

steroids are of many types..
some of the common categories of steroids:

Animal steroids
Insect steroids
Ecdysteroids such as ecdysterone
Vertebrate steroids
Steroid hormones
# Sex steroids are a subset of sex hormones that produce sex differences or support reproduction. They include androgens, estrogens, and progestagens.
# Corticosteroids include glucocorticoids and mineralocorticoids. Glucocorticoids regulate many aspects of metabolism and immune function, whereas mineralocorticoids help maintain blood volume and control renal excretion of electrolytes.
# Anabolic steroids are a class of steroids that interact with androgen receptors to increase muscle and bone synthesis. There are natural and synthetic anabolic steroids. In popular language the word "steroids" usually refers to anabolic steroids.
Cholesterol which modulates the fluidity of cell membranes and is the principle constituent of the plaques implicated in atherosclerosis.
Plant steroids
Phytosterols
Brassinosteroids
Fungus steroids
Ergosterols

There are steroids which are used by doctors for operations and are suggested to patients as medicines..
but now we are only going to discuss of those steroids which make a huge difference in humans... In popular language the word "steroids" usually refers to anabolic steroids.so we talk about anabolic steroids in specific..
A steroid has a capability of converting a normal human to a super human..
atheletes become worlds fastest human and body builders turn to giants...
and shot putters just throw away the shotput miles away...

howz this possible..??
this is an attempt to make a lay man understand what is a steroid and the ill effects of it..
By nature humans have got some standards and capabilities both biologically and physically..
steroids are an attempt to go beyond this nature..

WHAT IS A STEROID?
In simple terms a anabolic steroid is a male hormone TESTOSTERONE.male reproductive hormone..i.e steroid
is a man made testosterone in labs. .
this hormone is responsible for physical and biological changes in man at the age of maturity..
testosterone is released and males reproductive organs gain functionality ... growth of mustache and pubic hair are also
the observable changes...

HORMONAL CHANGES
At the age of maturity when this hormone is released the muscles of the males develop and their capability improves..
one such type of steroid is Anabolic steroids such as THG ...

THG's(tetrahydro-gestrinone)
THG's have been in demand in gyms and sports grounds for decades, and one study found that 9 per cent of body builders going to gyms in Britain were using them.
Made from the male hormone testosterone, they provide a chemical shortcut to strength and endurance. They promote the development of muscle, reduce fatigue and
speed recovery after physical exertion by stimulating the production of protein. This makes them especially attractive to sprinters, weightlifters and throwers
such as shot putters, for whom raw power is all-important....

EXPLANATION
when a person or a sportsman works hard for hours where he spends most of muscle power.. here the testosterone come into action...
they are utilized to maximum extent ... so the persons sexual power reduces ..people generally say that a person with jumbo muscles cant do the task but a cute boy with no muscles can do it....
so atheletes and others use steroids.. i don't say that it increases his sexual capability ..but it has ill effects instead..
when the steroids are taken in minimum amount it doesn't really affect him.. but to get a good performance in sports, and to build a good body these steroids are
taken in very large amounts.. this effects them drastically in both ways..
the ill effects of steroid are not observed as soon as they are taken but.. they have long term effects.. many persons after a age of just 40 have complains regarding their health who admit that they have used steroids
in their 20s... and there are cases of deaths registered because of heart attacks due to use of steroids..
after using steroids for just 1-2 weeks one can find the difference in his capabilities and structure of muscles..

The function of testes stops as intake of testosterone is more from outside into the body..
and there is no need for body to produce the hormone..
but if the user suddenly stops the usage of steroids the testis doesn't start producing the hormones and there are many other effects...
the person gets depressed and if he is alone he may attempt for a suicide.. so be careful ...
the person cannot stop the intake all of a sudden.. he should slowly stop it..

VERY POPULAR
steroids have become very popular and now a days they are available every where.. you may buy them over internet or
even u may get them at a local medical shop..
and in recent times teenagers are getting more addicted to steroids... so find them and stop them from doing this illegal practice..

UNDETECTABLE
The addition of four hydrogen atoms was all it took to make the anabolic steroid, gestrinone, undetectable by standard tests. A clever bit of work by chemists transformed it into tetrahydro-gestrinone (THG), providing some sportsmen, apparently, with the means to cheat.
The alarm was raised when a used syringe with a barely visible residue inside it was provided by an anonymous track and field coach to the US Anti-Doping Agency. From that residue, a University of California laboratory was able to identify the droplets as THG and then devise a test that would detect it in athletes' urine.

RISKS
Anabolic steroids carry many risks. They can harm the liver and may damage the heart by causing expansion of the cardiac muscle. They also promote growth of the bones, especially facial bones such as the jaw and teeth, and increase the risk of cancer.
One problem with detecting the use of anabolic steroids is that they are broken down and excreted by the body within five to 15 days but their effects are felt for three to four months.
Athletes may choose to use them during training and then stop a couple of weeks before a competition. Drug testing out of competition and at no notice were introduced to tackle this problem.
In addition to steroids, stimulants such as ephedrine are among the most widely abused drugs in sport. Erythropoietin, used by cyclists and long distance runners to increase the oxygen carrying capacity of the blood, is also in demand.


PUBLIC RESPONSIBLE
We public are considered to be the most responsible for this issue.. atheletes are taking steroid only to entertain us..
when people are expecting more from their favourite stars the the only alternate for them is to use steroids..
And to become famous they suddenly break records by using steroids.. All this is only to entertain the public..
We shouldn't encourage such practice.. lets unite to educate all about the risks involved and the degrading sports culture...
lets remake it and get it into the right path......

ALARMING
The most alarming issue is the usage of steroids by general public.. i don't know the reasons but i can interpret it as follows..
the growing challenges in the fast growing world wants people to work like machines..
they need to put more strain.. so to improve their work efficiency they are using steroids...
steroids not only build muscles but simply they enhance the persons ability in the work he does daily..
it may be running, shortputting ,body building or even industrial working etc

If u don't take care of this right now the results may be disastrous and more devastating..
the situation will be out of control..
so lets put a check to this.. And u public don't expect more from our sportsmen and atheletes..
so that to satisfy your expectation and entertain you they will not indulge in steroids....
lets hope they will perform only to their natural abilities but not created ones...

say no to steroids............
