[[Politics|Political]] pressure, however, has since made it impossible for anyone pursuing an academic career in [[science]] to even question the validity of this nonsensical [[equation]]. '''''Simply put, E=mc&sup2; is [[liberal claptrap]]'''''.
Light The formula asserts that the mass of an object, at constant energy, magically varies precisely in inverse proportion to the square of a change in the speed of light over time,<ref>http://www.livescience.com/29111-speed-of-light-not-constant.html</ref> which violates [[conservation of mass]] and disagrees with commonsense.<ref>The formula asserts that the mass of an object has energy associated with it, even when it is not moving (p=0). The formula asserts a relationship between the rest mass of an object, its energy and the speed of light. According to the formula, the apparent mass of an object depends on its energy and so [[conservation of mass]] is not satisfied. Instead, relativity proposes that the total energy of a [[closed system]] is conserved, when we &quot;convert&quot; the masses into energies using this formula.</ref> Physicists have never been unified able to unify light with matter <ref>Quantum Electrodynamics describes how matter interacts with matter, the standard model of particle physics describes how matter (fermions) interact with bosons (force carriers) for the electromagnetic, strong and weak forces. To date, no theory has been proven to unify gravity with electromagnetism.</ref> despite more than a billion-dollars-worth of attempts, and it is likely impossible to ever do so. <ref>Much of 20th century physics has centered around the interactions between photons (light) and fermionic matter, and much more than a billion dollars has been spent on this. But that doesn't imply that they have been "unified".</ref> [[Biblical Scientific Foreknowledge]] predicts that there is no unified theory of light and matter because they were created at different times, in different ways, as described in the [[Book of Genesis]].
[[Mass]] is a measure of an object's inertia, in other words its resistance to acceleration. In contrast, the intrinsic [[energy]] of an object (such as an [[atom]]) is a function of electrostatic charge and other non-inertial forces, having nothing to do with gravity. Declaring the object's energy to be a function of inertia rather than electrostatics is an absurd and impossible attempt to unify the forces of nature, contrary to the accepted view (as predicted by [[Biblical Scientific Foreknowledge]]) that the forces of nature have not been unified. Liberal scientists assert the formula E=mc&sup2; is not limited to nuclear reactions; it applies to chemical reactions and even to the energy stored in a compressed spring.<ref>http://www.newton.dep.anl.gov/askasci/phy99/phy99140.htm</ref>
The claim that '''E=mc&sup2;''' has never yielded anything of value and it has often been used as a redefinition of &quot;[[energy]]&quot; for pseudo-scientific purposes by non-scientific journals. Claims can be found not only on liberal, second-tier college websites but at those of [[Baylor]] and the [[MIT]] that the equation is used in [[nuclear power]] generation and [[nuclear weapon]]s ([[nuclear fusion]] and [[nuclear fission]]) and speculations about [[antimatter]].<ref>[http://www.pitt.edu/~jdnorton/teaching/HPS_0410/chapters/E=mcsquared/index.html John D.

The [[Theory of Relativity]] has never been able to mathematically derive '''E=mc&sup2;''' from first principles,<ref name="wvarticles"/>, and a physicist observed in a peer-reviewed paper published in 2011 that "Leaving aside that it continues to be affirmed experimentally, a rigorous proof of the mass-energy equivalence is probably beyond the purview of the special theory."<ref>[http://adsabs.harvard.edu/abs/2011AmJPh..79..591H Eugene Hecht: ''How Einstein confirmed E<sub>0</sub>=mc&sup2;'', American Journal of Physics, Volume 79, Issue 6, pp. 591-600 (2011)]</ref> Nevertheless, Robert Dicke - one of the most accomplished American-born physicists and experimental physicists in history - found it unlikely that the equivalence was wrong.<ref>R. H. Dicke "The Theoretical Significance of Experimental Relativity", Gordon and Breach, 1964</ref>
It has been known for a long time that radiation has a mass equivalence, which was correctly derived by [[Henri Poincaré]] in 1904,<ref>[http://www.opticsinfobase.org/josa/abstract.cfm?uri=josa-42-8-540 Herbert E. Ives ''Derivation of the Mass-Energy Relation'', JOSA, Vol. 42, Issue 8, pp. 540-543 (1952)]</ref> but the equation '''E=mc&sup2;''' makes a claim far beyond that limited circumstance:
The equation is extremely famous, and just as extremely misunderstood, in popular culture. Among the more outlandish claims are statements to the effect that "E=mc&sup2; holds the secret of the atomic bomb."<ref>Not so. The energy of the atomic bomb comes not from E=mc&sup2;, but from the tension between the electrostatic force and the strong nuclear force.

The equation has acquired something of a "cult" status. In the USA, the popular ''[[Twilight Zone]]'' series featured '''E=mc&sup2;''' prominently, giving the equation greater currency with the public. The song ''[[Albert Einstein|Einstein]] A Go-Go'' by the band Landscape had a similar effect in the UK in the 1980s.

Hundreds of years of research by chemists (and, before that, the alchemists) worked out the potential energies that are characteristic of various substances, and that the potential and kinetic energies are accurately converted from one to the other, leading to the principle of conservation of total energy.
An interesting fact is that, normally, one considers only ''changes'' in potential energy; one doesn't need an absolute scale. A rock at the top of a hill has more potential energy than after it rolls to the bottom of the hill, but the energy at the bottom isn't necessarily zero. We could dig a hole and let it roll down farther, with its energy going negative. Only changes matter. Now it turns out that, once one accepts the implications of E=mc², one ''could'' assign an absolute potential energy to something&mdash;its mass times c², and changes in potential emergy energy would work out correctly because of the mass changes. But that isn't necessary, and, in any case, it would require accepting E=mc² and would therefore be getting ahead of the story.
::'''Potential energy has mass.'''
That is, it weighs something. Whenever anything has potential energy of any kind in it, improbable as this may sound, it weighs more. The proportionality constant is 1/c<sup>2</sup>, or 1.11 x 10<sup>-17−17</sup> kilograms per joule. A fresh battery weighs more than a spent one, a wound-up alarm clock weighs more than a run-down one, etc.
Now that's way too small to measure for anything other than nuclear reactions, which is why it escaped everyone's notice for so long. But it has been measured and experimentally verified for nuclear transformations all across the periodic table.
One can verify that, in the non-relativistic limit, the relativistic values converge to the classical ones.
It is this requirement, and some "gedanken experiments" involving conversion between potential and kinetic energy, that lead to E=mc².<ref name="wvarticles"/>. These experiments involve some kind of object that isn't moving (though there might be internal motion that doesn't figure in the experiment) and therefore has no kinetic energy and only potential energy, turning into some things that have kinetic energy. The requirements of strict conservation of total momentum and total energy prove the equation.
Einstein's famous derivation<ref name="einstein1905b">[http://www.fourmilab.ch/etexts/einstein/E_mc2/www/ "Does the Inertia of a Body Depend its Energy Content?" Albert Einstein, Sept 1905]</ref> involved light instead of tangible objects, but the result is the same.
==History of Experimental Verification==
Because the change in mass arising from a given release of energy is so small ($1/c^2$, which 1.11 x 10<sup>-17−17</sup> kilograms per joule), it is essentially impossible to check this equation for normal processes. For example, a flashlight battery loses about 1 picogram of mass when it discharges, and the resultant atoms from the detonation of 1 kilogram of TNT weigh 47 nanograms less than the TNT. Even if all the particles of smoke and gas could be collected reliably, the difference couldn't be detected.
Measuring the effect requires process that release vastly more energy than ordinary chemical processes. The discovery of Radium and Polonium around 1898 gave a tantalizing hint that there were processes that released far more energy than chemical processes could account for. These elements continuously released measurable heat, and also glowed in the dark.
Einstein touched on this possibility in his original 1905 paper.<ref name=einstein1905b/>.
{{cquote|''It is not impossible that with bodies whose energy content is variable to a high degree (e.g. with radium salts) the theory may be successfully put to the test.''}}It would take more than a decade to develop an understanding of the nuclear process involved. The first thing that was required was accurate knowledge of atomic weights.
Atomic weights of the various elements were first measured, with accuracy of a few decimal places, by J. J. Berzelius in the late 1820's1820s. This required extremely painstaking (for the time) measurements. The figures were refined to even more accuracy by J. A. R. Newlands in the 1860's1860s. The values were accurate enough to clearly show the rather interesting property that the atomic weights were nearly integers, but not exactly so. The reason for this would turn out to be partly because of different isotopes (discovered by Frederick Soddy in 1913) and partly because of E=mc<sup>2</sup>.
In 1907 Rutherford determined that the "alpha" radiation from Radium was Helium. In 1911 he formulated the theory of the nucleus. In 1919 he demonstrated that nuclear transmutations could take place, such as
The 1932 Cockcroft-Walton experiment, described in more detail below, started to make the equation famous by confirming it, with reasonable accuracy, for an artificially induced nuclear reaction. (Confirming E=mc<sup>2</sup> was not a goal of the experiment; it was an incidental consequence. The equation had already been known and understood for many years.)
In the decades since, nuclear transmutations have been performed, in particle accelerators, all over the periodic table, observing in detail the properties of various isotopes. These have confirmed E=mc<sup>2</sup> with great precision. Perhaps the most precise test, by Rainville ''et. al.''<ref name="rainville">http://www.nature.com/nature/journal/v438/n7071/full/4381096a.html Nature 438, 1096-1097 (22 December 2005)] doi:10.1038/4381096a; Published online 21 December 2005</ref>, confirmed the equation to an accuracy See [[Quantitative Analysis of a few parts per millionAlpha Decay]].

==The [[Cockcroft and Walton Experiment|Cockcroft/Walton experiment]]==This experiment is not one of the ones usually cited as validating E=mc². That was not its goal.

But analysis of This experiment could not have proved any general truth to the equation, since it was a test of just one specific reaction. But data from this experiment does in fact verify was consistent with the equation for the particular transmutation involved.
They bombarded [[Lithium]] atoms with [[protons]] having a [[kinetic energy]] less than 1 [[Electron-Volts|MeV]]. The result were two (slightly less heavy) [[alpha particle]]s, for which the [[kinetic energy]] was measured as 17.3 MeV
Accurate measurements and detailed calculations allowed for verifying the theoretical values with an accuracy of ±0.5%. This was the first time a nucleus was artificially split, and thereby the first transmutation of elements using accelerated particles:

Perhaps best empirical verification of '''E=mc<sup>2</sup>''' was done in 2005 by Simon Rainville et al., as published in ''[[Nature (journal)|Nature]]'' (which is not a leading physics journal).<ref name="rainville"/> The article states that &quot;Einstein's relationship is separately confirmed in two tests, which yield a combined result of 1−&Delta;mc²/E=(−1.4±4.4)×10<sup>−7</sup>, indicating that it holds to a level of at least 0.00004%. To our knowledge, this is the most precise direct test of the famous equation yet described.&quot;
==A Famous Example -- Nuclear Fission of Uranium==
==A Topical Example: Speed of Extremely Energetic Neutrinos==
Here is another example of the use of this formula in physics calculations. In 2011 there were [httphttps://www.theguardian.com/science/2011/sep/22/faster-than-light-particles-neutrinos?newsfeed=true reports] that high-energy neutrinos had been observed traveling at a speed faster than the speed of light in an experiment at the Gran Sasso laboratory in Italy. Specifically, they seemed to have arrived at the detector 60 nanoseconds faster than light would have. Relativity doesn't allow that, and, since neutrinos have nonzero (but incredibly tiny) mass, they aren't even supposed to travel ''at'' the speed of light.
The mass of a neutrino is about 0.44x10<sup>-36−36</sup>kilograms. (Normally all of these things are measured in more convenient units such as Giga-electron-Volts, but that makes implicit use of E=mc<sup>2</sup>. If we don't accept that, we have to do the calculations under classical physics, using SI (meter/kilogram/second) units.) The neutrinos were accelerated to an energy of about 17GeV, or .27x10<sup>-8−8</sup>Joules. If one did not accept relativity and had to use classical physics and the classical formula $\mathrm{E} = \frac{1}{2}mv^2$, one would get v=110x10<sup>12</sup> meters per second. This is about 370,000 times the speed of light, something that scientists would certainly have noticed. In fact, with special relativity, the speed is just under the speed of light, such that the neutrinos should be received at the detector about .26x10<sup>-24−24</sup> seconds (.26 yoctoseconds) later than the speed of light itself. This is far too small to measure&mdash;15 orders of magnitude smaller than the resolution of the GPS signals in the experiment.
Later [http://news.sciencemag.org/2012/02/official-word-superluminal-neutrinos-leaves-warp-drive-fans-shred-hope%E2%80%94barely?ref=hp reports] started to resolve the mystery, and it is now accepted that the neutrinos behaved properly. But a BBC reporter made the incorrect statement that [httphttps://www.bbc.co.uk/news/science-environment-17364682 the neutrinos travelled at precisely light speed]. This was a simple misstatement, by .26 yoctoseconds.
The issue was discussed at length at Conservapedia.<ref>http://www.conservapedia.com/Talk:Main_Page/Archive_index/102#Faster_than_light_neutrinos</ref> <ref>http://www.conservapedia.com/Talk:Main_Page/Archive_index/102#The_final_nail_in_the_coffin_of_relativity.3F</ref> <ref>http://www.conservapedia.com/Talk:Main_Page/Archive_index/102#Another_Blow_to_Relativity</ref> <ref>http://www.conservapedia.com/Talk:Main_Page/Archive_index/109#Neutrinos_now_obey_speed_limit</ref> <ref>http://www.conservapedia.com/Talk:Main_Page/Archive_index/111#Neutrinos</ref>
==Deducing the Equation From Empirical Observation==
So, for the purposes of this section, imagine that one is in the era of "classical physics"; prior to 1900 or so. Relativity has not been invented, but, inexplicably, nuclear physics has. Imagine that the phenomena of radioactivity and nuclear fission have been observed, without any knowledge of relativity.
A well-accepted physical law of classical physics was the law of conservation of mass. This was not easy to deduce. It required careful analysis of such phenomena as combustion, in the 1700's1700s, to eliminate the various confounding sub-phenomena that made the law difficult to see. But, by 1900, the law was well established:
:::*'''In all interactions, mass is precisely conserved.'''
Radium-226 decays into Radon-222 by emission of an alpha particle with an energy of 4.78 MeV.
1 &nbsp;kg of Radium-226 = $\frac{6.022 \times 10^{23}}{226.0254}$ atoms. (The numerator is [[Avogadro's number]], and the denominator is the atomic weight of Radium-226.) This is 2.6643647 * 10<sup>24</sup> atoms.
That number of Radon-222 atoms has mass .98226836 &nbsp;kg. That number of alpha particles has mass .01770863 &nbsp;kg.The mass lost is .00002301 &nbsp;kg.
Each emitted alpha particle has energy of 4.78 MeV, or 4.78 * .1602 * 10<sup>-18−18</sup> Joules. The total alpha energy from the decay of 1 &nbsp;kg of radium is 2.04 * 10<sup>12</sup> Joules.
Also, Radon-222 decays into Polonium-218 by emission of an alpha particle with an energy of 5.49 MeV.
1 &nbsp;kg of Radon-222 = $\frac{6.022 \times 10^{23}}{222.0176}$ atoms. This is 2.7124611 * 10<sup>24</sup> atoms.
That number of Polonium-218 atoms has mass .98194467 &nbsp;kg. That number of alpha particles has mass .01802830 &nbsp;kg.
The mass lost is .00002703 &nbsp;kg.
Each emitted alpha particle has energy of 5.49 MeV. The total alpha energy from the decay of 1 &nbsp;kg of polonium is 2.39 * 10<sup>12</sup> Joules.
It looks as thought we have to rewrite the law of conservation of mass:
| alpha decay of Ra-226
| 2.04 * 10<sup>12</sup>
| .00002301 &nbsp;kg
|-
| alpha decay of Rn-222
| 2.39 * 10<sup>12</sup>
| .00002703 &nbsp;kg
|}
For Po, m/E = .113096234 E-16
If this is linear, the mass defect for TNT would have been .47 * 10<sup>-10−10</sup>. We couldn't possibly have measured this.
So we can rewrite the rule for conservation of mass in a more satisfactory way:
