thank you for the insight I never even considered the fact zero is neither positive or negative.

Is the problem with dividing by zero recognizing different infinities? to me 1/0 is clearily a infinitely large number(x). and 2/0 should be 2x. so x *0=1 assuming for examples sake(0/0=1) so 2x*0=2 I guess for this to work some abstract value of infinity must be defined in the...

Forgive me if this question is very basic but I have trouble finding a clear answer on it. In the big bang theory did space and time exist before? or was it created during? thanks

ok getting a little conflicting information i guess did i mess this up by putting the question as relating to relativity? is it relativity or string theory that says this? perhaps I am confusing mass with matter. I asked because i here people saying matter is only energy, but they give no...

E=mc^2 is this analogy or actually true(refering to the title question)? does that mean fermions themselves are energy, or do they have energy? is matter and energy 2 forms of the same thing? or is matter simply energy, and only appears to be different then energy to us?

javieR your answer really made me look at it differently, and it seems more logical. i think i see now why the rest mass must be zero in https://www.physicsforums.com/latex_images/23/2379621-0.png how ever i this other equation https://www.physicsforums.com/latex_images/11/1129330-0.png you...

also it doesn't matter the direction the photon approaches, the electron always increases in energy?

so its actually movement(in form of a wave or vibration) of the fields charged objects produce? so the photons would wash over the matter in wave form only affecting charged objects. any photon in collision with a electron is absorbed. why do photons not effect protons? sorry for all the...

so you are saying even the mass equation i used to get its regular mass, is incorrect and its regular mass is undefined to. so it has no mass even when its in motion. i just asked this question too. https://www.physicsforums.com/showthread.php?p=2379568#post2379568 quote: the way i...

the way i understand it is photons excite atoms, causing them to increase in energy. i view this increase in energy as jostling of a atom causing more movement of its proton, neutrons, electrons. i realize a photon is a particle and a wave(in limited comprehension.) so should i view the...

From my reading i am seeing the answer But according to special relativity, light ALWAYS travels with the light speed c, and is NEVER at rest and from this statement i am supposed to gather there is no rest mass. But logic tells me just because light is never at rest, doesn't necessarily...
