Dedication: For Elías, who very nicely gave me the cómic from which I have extracted similar adventure and with which I enjoyed a good moment. Clark Kent visits in prison Lex Luthor with the intention of doing an interview to him for Daily Planet. But, once there, it meets that the plans of the supervillain are not different that to escape and to scheme a diabolical plan to finish once and for all with his archenemy: Superman.
The prison is full of types of bad kind. Between them, the very special one, it is causing an authentic massacre, triumphing with everything and with all that it is to his step and that are opposed to his advance. It is a question of "the Parasite", a being capable to absorb energy, the superpowers and the intelligence of any that one which it manages to touch.
In a given moment, Lex Luthor begins to shoot him with a firearm. Immediately, Clark Kent realizes that something strange happens:
- The bullets do not stop it! It is turning the kinetic energy into more mass!
- You are right! - Luthor answers.
In spite of this serious mishap, the bullets rain continues incessantly. Until after a little bit:
- Him the energy is choking! [...]
- My bullets have had to of inclining the scales! It has become too massive to support its own weight.
Well: what do we have here? Nothing more and neither more nor less than a new adventure of superheroes and supervillains of cómic ready to defy the laws of the physics. In this occasion, the thing starts well, but it finishes regrettably badly. Let's see it.
Our horrifying bug, the Parasite, with this aspect of bigheaded slug and indented which lamprey, does not have in better what using his time than in absorbing the kinetic energy of the bullets that fall down on his purple corpachón. You know many of you that the kinetic energy is that that they possess the bodies in reason of his speed. In physics, it is possible to calculate multiplying half of the mass of the body by the square of his speed. Well, if we give them to the bullets that a few values go out of the weapon of Lex Luthor more that generous so much for his masses as his speeds of, we say, 40 grams and 1000 m/s, respectively, at once appreciates that every bullet possesses a kinetic energy of 20.000 joules. This can look like an enormous energy quantity and certainly it it is, especially if it impresses you in the face, in a foot or in any another more sensitive and delicate part of your delicate anatomy. Nevertheless, to the Parasite him mola mallet. Moreover, apparently, all the more better kinetic energy, since this helps him to transform it into mass of its own body and be bigger and more fear gets for the head.
Now then: does turn out to be commendable to turn energy into mass? Since I have not left any more remedy than it to allow. Yes, one can. In fact, m was Albert Einstein who established of quantitative form the equivalence between mass and energy, across his most famous equation E = c2. This expression affirms (and his validity has been confirmed in infinity of occasions, some of them of unlucky memory) that the matter and the energy are, in fact, the same thing. The smallest matter quantities can give place to enormous energy quantities, and quite through the fault of the value of the speed of the light (her c in the previous equation, which also is raised to the square). The mass conversion in energy we see it every day in the nuclear power plants, where the fuel serves to supply partially of electric power the hearths. In the detonations of nuclear explosives identical process takes place, with the proviso of which the energy liberation is not controlled, as it happens in the nuclear reactors. On the other hand, the inverse process, this is the energy conversion in mass, it is usually more difficult enough to manage. Where can we attend this process? Since it usually happens often in the big particle accelerators, where you do of these they make clash at enormous speeds, producing the generation of new particles at the expense of the kinetic energy that the first ones were taking initially. You will wonder, then, where the snag is with our protagonists, the Parasite and Lex Luthor leave to me that I explained it to you.
Anyone that tries to change in the "boutique" of the energy, kinetic energy for mass, is not going to meet reductions precisely. There is always going to cost him the same, that is to say, a price given irremediably by Einstein's equation. This way, replacing in the value of E the quantity of 20.000 joules that had every bullet of those that the Luthor weapon was shooting and clearing the value of m, it is had that this is approximately 0,22 billionth ones of kilogram (the physicists we call the kilogram billionth ones with the nice name of nanograms). What means this? You can find out it yourselves easily. It means that so that the mass of the Parasite increases in only a miserable gram 4500 have to fall down on his body neither more nor less than millions of bullets. In what case does similar Lex Luthor take bullets quantity? Moreover: how does he support the weight of the same ones, if this one reaches 180.000 tons? (remember that every bullet was weighing 40 grams).
And above, the very nice one goes and says after a little bit that his bullets are inclining the scales, that the Parasite has absorbed so many people that his weight is superior to the one that he can support. Luthor, you are pasao, the law Sinde has fucked the quijotera to you. Let's leave the closing webs aside for better occasion and centrémonos in the last affirmation of the “more brilliant genius of all the times”. That you know this blog from the beginning you know the incredible law of the square - bucket or law of the scale. In those primerísimos posts it was telling you that a living being, an animal or a person cannot grow up to an arbitrary size because then he might not support his own weight and this was happening as soon as the relative force was reaching an equal value to the unit. Well, if we grant him to the Parasite a value of 3 for the relative force when it possesses his normal size, that is to say, the force that is capable of supporting his corporal structure is the triple of his weight, Luthor of that time will be right when the volume of the abominable being absorbs - energía-cinética 27 increases in a factor or, what is the same, his mass makes 27 times major to itself. Consequently, and assuming 100 kg mass for the Parasite when this one still has not assimilated suppository of any lead, Lex Luthor will need to introduce for the eyelet the not despicable at all number of 11.700 trillion bullets …
