Zitat:

E=mc? Fallacies and the Non-Conversion of Mass to Energy

The formula E=mc? has long been interpreted to mean that the rest mass of matter could be converted into the energy of massless photons and that the kinetic energy inherent in the motion of bodies of mass increases the mass of those bodies. The validity of this idea rests on the arbitrary assumption that the photon has no mass. However, a classical interpretation of photon experiments would identify the photon as a particle of mass. Experiments show that photons have both energy and momentum and each of these is associated with the motion of mass. A careful examination of these experiments will show that energy and mass are separate and distinct parameters and that one is never converted to the other.


E=mc?

What does E=mc? really mean? This deceptively simple equation is known by nearly everyone to be one of the ultimate secrets of the universe, yet almost no one has the slightest idea of what it says or how it really works.Five widely-believed fallacies about this formula can be found throughout
the most general to the most technical scientific literature.


Fallacy # 1:
E=mc? means that matter can be converted into energy.

It is believed that when an atomic bomb explodes, matter is transformed into enormous amounts of energy. This is not true. After the explosion, all of the original matter still exists. All of the protons, electrons, and neutrons making up the uranium, plutonium, or tritium are still within the mushroom cloud. Elements were transformed, neutrons were split into protons and electrons, and protons and electrons combined into neutrons, but in no case was a single particle of matter converted into energy. All of the original components needed to reconstruct the transformed atoms to their initial nuclear states are speeding away in all directions and could, in principle, be reassembled back into the original nuclei. The same exact number of protons and electrons exists after the explosion as existed before. To reassemble these components would require the same amount of kinetic energy that was released in the explosion.

The energy of the explosion comes not from converting matter to energy, but from the kinetic energy released when the light elements combine and when very heavy elements break apart. This energy did not just appear from a miraculous transformation of matter into energy, but was always contained within the internal motions of the electrons and protons making up the structure of the fissioning or fusing atoms. The only transformation that occurred was the conversion of rotational kinetic energy into linear kinetic energy.


Fallacy # 2:
E=mc? means that mass can be converted into energy and energy can be converted to mass.

This also is not true. For example, much of the energy of an atomic explosion comes from the decay of neutrons that have a mass .0078 times greater than the combined rest masses of the proton, electron and neutrino decay products. However, this .78 MeV of mass does not disappear or convert to energy when the neutron decays. Most of the energy of the decay is contained within the high velocity of the electron as it is thrown from the much heavier proton.

The Lorentz transformation mass increase produced by this velocity and to a much lesser extent the velocity of the proton and the neutrino accounts for all of the extra mass contained within the original neutron. The combined masses of the products of a neutron decay are exactly the same as the mass of the original neutron. The surplus mass of the neutron is kinetic mass produced by the rapid spinning of it components. When the neutron breaks apart this same exact quantity of kinetic mass is still contained within the rapidly moving decay products.

There is no conversion of mass to energy because mass always remains constant both before and after the decay. Of course as the electron and proton are slowed by collisions with other matter they will loose much of this excess kinetic mass, but only by transferring it to the atoms with which they collide. For example, the electron might interact with many atoms and transfer a little of its kinetic mass to each one by increasing their velocity as well as the rotational kinetic energy of their components. When it comes to rest, all of the electron?s kinetic mass is gone, but it still exists in the atoms that slowed the electron to a stop and thus gained velocity in the process.

It is also possible that the electron will hit an atom in just right place and with just the right velocity so that it combines with a proton to form a neutron. Still there is no mass change in either case. Either the electron gives up small amounts of its kinetic mass to many different particles before it comes to rest or it combines with a single proton and keeps all of its kinetic mass as it forms a neutorn. It has the same amount of rotational motion inside the neutron as it had linear motion before it struck the proton and the kinetic mass inherent in these motions remains unchanged throughout the reaction. Mass does not change into energy and energy does not change into mass. The only transformation occurring here is the conversion of rotational kinetic energy to linear kinetic energy and vice versa.

For a real world example of this, consider a large flywheel constructed from some strong but brittle material and powered by a very high-speed electric motor. As the moving electrons within the windings of the motor are slowed and loose energy the velocity and energy of the flywheel are increased. As it spins faster and faster the wheel?s kinetic mass increases in direct proportion to its increasing rotational kinetic energy. Eventually, the speed of the wheel becomes so great that the centrifugal force exceeds the tensile strength of the wheel and it shatters into numerous pieces that all fly off in different directions along the plane of rotation. The kinetic mass of the spinning wheel is now divided among the kinetic masses of the individual pieces.

[Formrl]

The kinetic mass (KM) of the spinning wheel is equal to its rotational kinetic energy (E) times its rest mass (Mo) divided by the speed of light squared (C?).

[Formel]

The kinetic masses (KM) of the individual pieces of the wheel is equal to their rest mass (Mo) divided by the square root of 1 minus their velocity squared (V?) divided by the speed of light squared (C?) minus their rest mass (Mo).

The total mass in this experiment is constant. Mass is transferred from the electrons in the wire to the wheel and the pieces of the wheel retain that mass after it explodes. Mass moves from one interacting body to another but its total quantity is never altered in the slightest.


Fallacy # 3:
E=mc? means matter and antimatter can be annihilated into pure energy.

It is true that electrons and positrons or protons and antiprotons can combine and then split into photons, but a photon in no way fits into the metaphysical concept of ?pure energy.? What is pure about the energy of an object that has a precise wavelength, momentum, angular momentum, spin polarity, frequency, and velocity yet will be measured to have different values from these by moving observers? The fact that a photon?s energy as well as some, but not all, of its other parameters have different values for different observers implies that the photon has a definite physical structure. The motion of this structure has energy but it is no more pure than the energy inherent in the flywheel?s motion or that of a bullet.
