Mass and charge

[kolahal_b]

Can there be any connection between mass and charge?Why do some elementary particles,which are believed to have mass, also have charges while others not?

[ronthepon]

Probably not. Electrons have the same mass as positrons, yet opposite charge, and protons also have the same charge as positrons and yet a much larger mass.

[arkain101]

Then there is neutrally charged particles, with mass.

 

You have a good question though.

 

Since mass and charge are not very well understood, they are not fundamentally described, so it kudo's to you for questioning those concepts instead of leaving them at bay.

I asked this question on a definite ground.Few days ago, I attended a lecture by Prof.Penrose at his 75th birth ceremony in SINP.He told in a significant way that the fundamental constants of nature might change at the eve of next big crunch.Mass ratio of elementary known particles might change...Well,I told some of these possibilities to my friends before attending this lecture.Here I should say, I do not know anything of cosmology, just read about the big bang, matched it with the explanation of CREATION as found in Indian epic Mahabharata, and have self developed some ideas...

I thought since at the very moment of big bang,universe starts expansion from a point, I may well suppose that everything is massless at that stage.To make the point have highest amount of energy, it is required to have all mass converted to energy and the point to be static.A moving point would have kinetic energy and hence a less potential energy.This point may also be defined as the static point ever conceived in the universe.It needs also to have all electromagnetic energy of the universe also to contribute to the energy content of the point. Well,when everything we talk of is regarding energy, and those energy will make it unstable, there should not be any discrimination among various types of energy.EM energy and Mass energy would play the same role.I thought,also EM field and Gravitational field are basically do the same and if so why not we say the same for charge and mass.For some reason unknown to me yet, the scale in which they effectively expressed themselves is grossly different.But, that does not hamper the physical reality.Well, please note I have not read GTR or QMech stil now.So there is enough chance that I have written down all wrong over here.Please, if they require modification, modify them, with proper reasoning.
