# E=MC². What does formula E=MC² really mean?

Does this idea fit into the category of pseudoscientific?
E=MC². What does formula E=MC² really mean?
It means that Energy is equal Mass at speed (C²)
Quantum energy is a pure mass and vice versa.
The pure energy/mass is relativistic and depends on its light speed.
Quantum of light has relative energy/mass.
As light approaches the speed of ‘‘C’’, its relativistic mass/energy
increases to infinity (from observer views).
Relativistic energy/mass is about the nature of light itself.
Einstein’s SRT is about the nature of quantum of light
( at state ‘‘C’’ and at state "C²’’ — when the speed of light starts from “C” and
would go to the C² and therefore the Lorentz laws of transformation is needed to use)

or

That’s what E = Mc^2 means.

It is this small an amount of matter that can generate that large of amount of energy.

Did you know that in order to trigger the nuclear fission process, the bomb must be triggered by an initial conventional “inward” explosion?
That initial explosion imitates the Mc^2 and starts the fission process which then proceeds to reinforce itself and continues to cascade throughout the bomb until all fisionable materials are spent .

How? . . . . . . . . .

AFAIK, the nuclear device is in the center of the bomb and surrounded by dynamite, which in turn is surrounded by an incredibly strong shell that can withstand the outward pressure when the dynamite is exploded. Thus all the power of the dynamite explosion is turned inward and the pressure generated by that mechanism (E = Mc^2) is sufficient to start a nuclear event, which then ignites the rest of the fissionable materials in a chain reaction and all the inherent energy contained in the fissionable matter becomes explicated by the mega-nuclear event. The resulting mushroom cloud rising up to 60,000 ft. indicating the extraordinary power contained in a few pounds of nuclear fissionable material.

# atomic bomb

fission device

The core of an implosion-type atomic bomb consists of a sphere or a series of concentric shells of fissionable material surrounded by a jacket of high explosives, which, being simultaneously detonated, implode the fissionable material under enormous pressures into a denser mass that immediately achieves criticality. An important aid in achieving criticality is the use of a tamper; this is a jacket of [beryllium oxide] or some other substance surrounding the fissionable material and reflecting some of the escaping neutrons back into the fissionable material, where they can thus cause more fissions. In addition, “[boosted fission]" devices incorporate such fusionable materials as deuterium or tritium into the fission core. The fusionable material boosts the fission explosion by supplying a superabundance of neutrons.

Fission releases an enormous amount of energy relative to the material involved. When completely fissioned, 1 kg (2.2 pounds) of uranium-235 releases the energy equivalently produced by 17,000 tons, or 17 kilotons, of [TNT]

The detonation of an atomic bomb releases enormous amounts of thermal energy, or heat, achieving temperatures of several million degrees in the exploding bomb itself. This thermal energy creates a large fireball, the heat of which can ignite ground fires that can incinerate an entire small city. Convection currents created by the explosion suck dust and other ground materials up into the fireball, creating the characteristic mushroom-shaped cloud of an atomic explosion.

The detonation also immediately produces a strong shock wave that propagates outward from the blast to distances of several miles, gradually losing its force along the way. Such a blast wave can destroy buildings for several miles from the location of the burst.

How does dynamite do that? Pressure is force per unit area. What has E=mc^2 got to do with that? Force is power/velocity. Power is work/time. Work is force x displacement or change in energy. So how does dynamite detonating involve the speed of light? How does the v in 1/2mv^2 become c with just dynamite? Not that dynamite is used. A stick of dynamite produces a megajoule of energy. Its mass converted to energy is about 20,000 MJ.

I condensed my description of the process. Mc^2 = mass in motion = kinetic energy

The imploding mass compresses the fissionable material until a critical point is reached and fission starts. This does not require the imploding mass to move @ “c”, but just enough to compress the fissionable materials a specific amount.

The quoted portion from the link explains the process in depth.

Even the nuclear explosion does not reach Mc^2 to release an enormous amount of energy.
Mc^2 is a theoretical limit. Anything in motion generates energy.

That is not the equation for kinetic energy.

I am not proposing that. But mass in motion does generate kinetic energy.
An explosion sets mass in motion, no?
In this case, the implosion causes the fissionable material to condense and reach criticality.

Correct.

So

What does that propose?

Energy = Mass x c^2 is self-explanatory, no?

E = mc2.

It’s the world’s most famous equation, but what does it really mean? " Energy equals mass times the speed of light squared ." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

https://www.pbs.org/wgbh/nova/einstein/lrk-hand-emc2expl.html

E = mc2, equation

E = mc2, equation in German-born physicist Albert Einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c2) is equal to the kinetic energy (E) of that body.

I read that to mean energy is generated by mass in motion, i.e. either an explosion or an implosion are causal to mass in motion and the generation of energy at any speed.
M x c^2 is the ultimate limit imposed on the generation of energy.

Yes, correct, apart from you missed the power function for E and it’s not (Mass x c)^2 that = Energy, what’s that got to do with kinetic energy and dynamite?

The dynamite is used for the implosion (kinetic energy) to reach critical fission threshold that must be held to below the critical mass until used. Can’t have an atom bomb explode on the plane.

Basically the initial explosion arms the bomb and triggers the chain reaction.
See the illustration of the three types.

Dynamite isn’t used. The bomb is armed prior to any explosion. What mass is in motion in E=mc^2?

# atomic bomb

In practice, an assembly of fissionable material must be brought from a subcritical to a critical state extremely suddenly.

One way this can be done is to bring two subcritical masses together, at which point their combined mass becomes a critical one. This can be practically achieved by using high explosives to shoot two subcritical slugs of fissionable material together in a hollow tube.

The core of an implosion-type atomic bomb consists of a sphere or a series of concentric shells of fissionable material surrounded by a jacket of high explosives, which, being simultaneously detonated, implode the fissionable material under enormous pressures into a denser mass that immediately achieves criticality.

In my condensed summation I left out a lot of detail that you must also read in order to understand the mechanics of the 3 types of nuclear bombs.

You need to quote where it says that dynamite is used.

I don’t need to read anything but that.

And how dynamite imitates e=mc^2

OK, I should have used the term “conventional explosives”. I used dynamite as a shorthand term.

But the following should explain the mechanics of an initial conventional explosision to bring about an instantaneous nuclear fission chain reaction.

Until that initial explosion (implosion) is triggered, the fissionable materials are kept separate to avoid criticality. The explosion brings the separated nuclear materials together with great force and pressure to instantiate criticality.
(Think of a bullet being fired by the explosion of the primer to ignite the gun powder).

As I said, I don’t need anything else. And again, what have conventional explosives (fast AND slow, Composite B and Baratol) got to do with the imitation of e=mc^2?

What does the quote say?

That does not mean the nuclear materials explode all by themselves, they are being kept separated until the conventional high explosives compresses the separated nuclear material and criticality for nuclear reaction is achieved. How can you not see that written in plain language?

What about it? How does that imitate e=mc^2?

The initial explosion of the high explosives (mass) creates sufficient energy (kinetic energy) to compress the fissionable materials. It has nothing to with the speed of light for that specific purpose.

E= Mc^2 is an equation, it is not a law or a function.

Equation

In mathematics, an equation is a statement that asserts the equality of two expressions , which are connected by the equals sign “=”. … The variables for which the equation has to be solved are also called unknowns, and the values of the unknowns that satisfy the equality are called solutions of the equation.
