You say that matter is mostly energy, earlier (08/11/2009 19:27:40) do you not believe that matter is 100% made up from energy.
I suspect that matter is 100% made up of energy. However, others suspect that it is not. So I don't always advocate my own suspicions. I sometimes use the prevailing wisdom and subjugate my own suspicions.

To begin, you add flour and then water, mix into a dough and let it set. Then after baking, do we still have essentially the same ingredients we began with?

Sure, it's just in a different form :)

I do appreciate your feedback, as I understand it there are two types of challenging,

One, able to challenge,
Two, able to be challenged.

I am not able to challenge the math side of it as much as I would like, all I am doing is making observation based theory.

The mass of an object is proportional to its total energy, including the kinetic energy. Mass and energy are related by the famous formula E=mc^2, where c is the speed of light, E is the energy, and m is the mass. If you put any kind of energy into an object (by heating it up, or making it move faster, or charging up a battery, etc.), the mass increases. We don't ordinarily notice this, because c is such a big number that a little mass goes a very long way in the energy department. G is a constant used when calculating gravitational force between two masses.

I agree, mass and energy is the same.

Energy and matter is not though.
The Equivalence of Mass and Energy.

Which is really weird :)
If it's correct.

And also seems to put some emphasis to the 'classic' wave/particle duality actually being correct.
That means, there is a real difference between a particle and a wave.
So that when discussing wavepackets one moment, deeming them photons the next one's actually wrong.
Or would that be overstating it, as the photon only is defined by its momentum?
Ah, and energy of course :)
Awhh.
