There IS NO logical or any other relation "between the energy contained in
a mass and the speed of light" (your words).

'

A moving mass can 'exert,' give off - and thus "contains" - the energy,
equivalent to the size of the mass AND equivalent to the square of the
speed it has - to hit something else with; and that defines energy in
Coarse Particle Physics (CPP).

Newton already formulated that - (but he was wise enough to publish it
before the 'invention' of the Nobel Prize for Physics .

'

Thus it, the mass of the photon, with its speed of light, hits an
electron, and that electron now has obtained the available energy,
as equivalent to mass times velocity squared, from the photon.

In other words, photons are particles (that additionally vibrate as well).

This last sentence they did not pronounce, at your school, I assume - (in
order to discourage or even to disable you from studying physics .

'

It's really very simple - for those with some Sanity - relatively
speaking, of course.

But simplicity and truth is most violently and most intelligently
OPPOSED by the very Insane and Malicious - and with great success.

'

The very highly Insane Einstein, (Albert) has DESTROYED physics,
and the equally Insane Hawking, (Stephen) really finished it off -
the job of (jamming, blocking, diverting) destroying physics.

Tells you more than enough about other "physicists" who worship and who
believe in those very destructive (and in other) gurus, RATHER than to
observe and to think by themselves.

Hi everybody,

I have a question which bothers me since long time and maybe with your
help I can find the answer at last. Since I heard the formule E=mc^2 for
the first time it struck me that there seems to be no logical relation
between the energy contained in a mass and the speed of light. I have no
difficulties to understand that the energy contained in a mass is
equivalent to that mass.

My problem is: what the hell has this to do with the speed of something
else (an electromagnetic wave). I cannot see the connection between them.
These two things: mass and energy on one side and the speed of light on
the other side seem too disparate to me to allow a logical link between
them.

I wonder, if someone can explain this connection. I wouldn't have been
surprised if the Joule (the unit for energy) had been established in
consequence of this formula, but I think both Joule, kg, m/s were already
existent before E=mc^2.

I learned from Wikipedia that James Joule died in 1889, thus before
Einstein discovered his famous formula, which I think happened in 1905.

Greetings
Jacques
