Can anyone tell me what they think matter is? What they think composes protons, neutrons, electrons, positrons, etc?
I think you're already confusing two things: matter and mass. Matter is stuff; mass is a property of stuff.
DDarcade this physics site is not a speculation site. You can only ask people to tell you what the current 'research' and papers say.
Huh? Does that mean that people can't discuss ideas? I was under the impression that as long as you are willing to accept established facts, you can speculate all you want about things that aren't facts yet. It seems to me, that what you are saying would mean that the forefront of physics research would be secluded from posting here. Isn't string theory, LQG, E8 etc highly speculative?
Where's the line here?
I for one has never read anything even remotely adequate in explaining what mass/energy is. It's all more about how it behaves?
So, to me, the question from the OP sounds like one where it IS ok to speculate.
But maybe it's just philosophy, I don't know.
If the "speculation" is not based on peer-reviewed papers
then it doesn't belong here and one is making one own's personal theory.
Our policy on speculative, personal theory has been clearly outlined in the PF Guidelines that everyone has agreed to upon joining.
yes, that's pretty much what I wrote.
Why is that you equate speculation with making a theory? Speculation can be used to show that you don't understand this and that and then the ones who know the subject better can clarify. Not? As long as you don't try to assert anything. I mean, most good teams work like that. Bouncing ideas until the right ones emerge.
Yes, and I understand them. I just think you may be overeacting a bit here. I understand
we need rules on these forums, but why must things be so square? Instead of complaining about the formulation of the question, one can just post the paper(s) describing what mass is and move along.
The LHC is trying to find out as we speak. From what I understand, mass is supposedly the interaction that occurs between the Higgs particle and the other elementary particles.
The European Journal of Physics wants 30 pounds of sterling silver, and they will allow me to read all about mass.
Is there anything that satisfies only one of the above condition? - like, has mass and do not occupy space - or - has no mass and occupies space.
