Total Electric Charge: Is Our Universe's Zero?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether the total electric charge of the universe is zero. Participants explore theoretical implications, the relationship between charge conservation, and the matter-antimatter asymmetry in the universe.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants question the total electric charge of the universe, suggesting that no confirmed theory can definitively prove whether it is zero or non-zero.
  • Others express curiosity about the reasons behind the perceived imbalance of matter and antimatter in the universe.
  • One participant proposes that the answer may depend on the validity of charge conservation in all reactions and the initial conditions of the universe, noting that while the first is testable, the second may not be.
  • A participant indicates their support for the idea that the total electric charge is zero by voting in favor of it.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the total electric charge of the universe is zero, and multiple competing views remain regarding the implications and underlying theories.

Contextual Notes

The discussion highlights limitations in current theories regarding charge conservation and the initial conditions of the universe, which remain unresolved.

Do you think the total electric charge of Our Universe is zero?

i'd rather ask: "why do you think that it is (non-)zero?"
 
Because no confirmed theory can prove or disprove yes or no answer to this question.
Also, why is there more matter then antimatter in Our Universe?

huh! i hope that the poll results here and now, on physicsforums, will finally give the answer to this question!
 
I have also voted yes :)
 
This depends on two things, I guess:

1) The validity of conservation of charge in all reactions.
2) The initial conditions of the universe.

The first is testable, but the second probably isn't, so I don't think I can even guess.
