I checked google and all they have is E means energy.But what energy?Maximum energy?

LLand314 said:The equation to tell us exactly how much energy a given amount of mass represents.
mathmaniac said:I think Energy is compression or stress.So here energy means the total amount of compression of space inside a mass,which is the same as the amount of energy it contains?Am I right?
I like Serena said:The next step is to say that both mass and energy are illusions.
They are mere representations of a hyperdimensional space that is bent in such a way to create the illusion of mass-energy.
I'd like to think of that as stretching instead of compression though.
Near a mass the space continuum stretches into a sort of pit, making other masses fall into it.
The equation though is giving the pure energy; pure energy is electromagnetic radiation and electromagnetic radiation always moves at the speed of light which is why c is there.mathmaniac said:I think Energy is compression or stress.So here energy means the total amount of compression of space inside a mass,which is the same as the amount of energy it contains?Am I right?

mathmaniac said:Pure energy is space,electromagnetic radiation is space,c is space,everything is space...
This is what I think...
Please tell me if you think this is right or wrong...
"E" means how much the space is compressed in a mass.Right or Wrong?

Bacterius said:It's meaningless since you haven't defined any of the terms you use. How does the speed of light equal space? What does "compressed space" mean? How can you be "in" a "mass", do you mean density?
To be honest I'm not sure this thread contains much information,
this kind of physics doesn't really mean anything to the layman until he has some kind of background in relativistic and quantum physics (and I'm not claiming I have said background).
It sounds cool to say that "mass is energy" but it doesn't really mean anything without proper definitions and context. It may, however, incite further research and spark an interest in the relevant field, which is a good thing.
I think it's neither right nor wrong.
You have been answered, you just don't like the answers! And from you "thoughts" the reason appears to be that you do not know what energy itself is. You talk about "compression" which is a force, not a type of energy at all.I was asking what Einstein meant by "E"
but never got a satisfactory reply so far.I was to give more clarification and information of my thoughts and that's all I did.o

Mass and energy are concrete and distinct concepts that exist in a kind of "duality." When we say that E = mc^2 we are not saying that mass and energy are the same. By some process we may be able to convert all the mass of a particle into energy but the equation merely says how much, not in what form it will take. (Sorry Mr. Spock. There is no such thing as "pure energy.") For example if we collide an electron with a positron (an anti-matter electron) we get 2m_ec^2 of energy from the collision, plus whatever energy due to the overall momentum of the system contributes. But what form does that energy take? Most commonly as a photon. But it could also be a Z_0 particle, or a graviton, etc. (No single gluons. They have a special property called "color" and we can't directly observe this. You could have a "glue-ball" though which is a combination of more than one gluon in a semi-stable non-color state.)The next step is to say that both mass and energy are illusions.
topsquark said:I suspect that some of the problems here are due to language. However two things strike me:
1. You keep referring to a "compression." A compression of what? I don't have any idea what you are talking about here.
2. I believe you mentioned that all energy is made up of photons.
This is my attempt to make things clear. Many of these concepts have already been mentioned by others. Is there any specific question you have about this?
graviton
When Quantum physicists deal with particles we put the interaction in free space. This is a microscopic viewpoint and not shared with Classical, or macroscopic, Physics. I am assuming that the conversation is centering about subatomic particles so there is nothing to compress in this case.mathmaniac said:compression of whatever it is in.And atlast maybe compression of aether.
Pair production of electrons and positrons is the interaction:mathmaniac said:Doesn't "Pair Production" imply this as it implies that an electron is in a way "a photon stopped"?
As I mentioned in my last post when mass is converted to energy it has to be carried off by something, like photons, etc. Energy cannot exist on its own... it has to be carried off by a particle of some sort.mathmaniac said:So what happens if all the mass is converted?massless photons?
Gravitons (the particle field interpretation of a "gravity wave") are a tricky subject right now. No one has been able to detect one, but the theory of their existence seems sound. You can derive many of the properties of a graviton by looking at General Relativity and they are commonly used in Quantum Mechanics. And besides if you have two objects orbiting each other energy is lost to something as they spiral inward. For the moment we attribute the mechanism of such energy loss as the emission of gravitons. (For the record gravitons, like photons, are massless.)mathmaniac said:Is there any evidence for it?A special particle for gravity?Seems insane to me..
