Discussion Overview

The discussion revolves around the concept of a Sea of Dirac, inspired by the anime Neon Genesis Evangelion, and its potential relationship to naked singularities. Participants explore the implications of such a connection within the context of astrophysics, theoretical physics, and the historical development of the Dirac Sea concept.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that a Sea of Dirac could be a naked singularity or contain one, questioning the conceptual feasibility and implications for astrophysics.
  • Another participant provides a historical overview of the Dirac Sea, explaining its original purpose in predicting antiparticles and addressing the negative energy solutions in quantum theory.
  • Concerns are raised about the acceptance of the Dirac Sea concept, with a participant noting that it has been largely surpassed by modern theories that treat negative solutions differently.
  • A later reply questions the relevance of the Dirac Sea to singularities, stating that the theory does not incorporate singularities and suggesting that the concept may have been fabricated or misunderstood.

Areas of Agreement / Disagreement

Participants express differing views on the relevance and validity of the Sea of Dirac in relation to naked singularities. There is no consensus on the connection between these concepts, and the discussion remains unresolved.

Contextual Notes

Some participants highlight limitations in the current understanding of the Dirac Sea and its implications, noting that the theory may not be applicable to singularities and that the concept has evolved over time.

Hello all! I come in peace... sort of. :biggrin:

As i was watching the anime Neon Genesis Evangelion, where one of the alien characters had the ability to capture its opponents in a Sea of Dirac, which was claimed to stretch over 800 meters in diameter, but had a thickness of only 3 nanometers, an idea sprung in my head.

What would happen if a Sea of Dirac was actually a naked singularity, or held one, if that was even conceptually possible? If such an object was found to exist, or the possibility of its existence was established by new mathematical insights, what would be the ramifications in astrophysics be?

The official word on the reference to the Dirac Sea in the Anime is as follows:

"The Sea of Dirac is defined on this story as a posible parallel universe. The interesting thing about Mr. Paul Dirac (the creator of this theory) was the existence of a posible universe composed only by energy. If all these was asumed as certain, its possible to understand that this "sea" is in fact the second part of the 10 dimensions which became fractured on the Big Bang (4 in our universe and 6 on the other). According to theoric physics, in order to open a "door" to this universe would be necessary something called "Plank Energy", something virtually imposible, but on black holes. But on this story there are various references to a limitless energy.."

I am greatly interested in your comments, denials, clarifications, explanations, or even the horse laugh.

My apologies on demonstrating newbie behavior by posting in the incorrect forum. :rolleyes:
 
*bump* The question couldn't have offended anyone's finer sentiments. What gives? :confused: Is there a secret handshake I'm supposed to know or some arcane mathematical formula i forgot to add? :-p

Hi

As far as I am aware the "sea of Dirac" was a concept that Dirac came up with to explain the existence of antiparticles - which he predicted from relativistic quantum theory.

Dirac noted that the equations (originally formulated for free electrons) permitted negative energy solutions, but if negative energy states were available then surely the electron should "runaway" to these increasingly negative states - radiating off an infinite amount of energy in the process.

To save his theory Dirac proposed that the negative energy states were already filled by an infinite "sea" of electrons. Because this sea is always there, and perfectly uniform, it exerts no net force and we are not aware of it. The Pauli principle doesn't allow any 2 electrons to occupy the same state which explains why the electrons we do observe are confined to positive energy states.

If you supply enough energy to an electron in a negative energy state it will jump into a higher, positive, energy state leaving a "hole" in the electron sea which has all the properties of the electron (like same mass) but opposite charge.

People weren't too happy to accept the idea of a sea of electrons, and this idea has been surpassed by Feynman and others. The modern theory treats the negative solutions as positive energy antiparticles.

This might be what you're looking for, might not, but there are no singularities in the theory (it's not even used anymore) and the sea of Dirac would be a lot bigger than they say it is.

Maybe...just maybe - they made it up?

Thank you but i fail to find anything in the link that refers to both Dirac and the naked singularity. One section dismisses the big bang-as-singularity notion, thanks to quantum mechanics. The reference to Dirac is largely incidental.

I already understand the basics. This proposal was offered in order to get a theorist' perspective... :smile:

Thanks, Darkbob! :smile:
