Creation of our universe from zero energy?

Click For Summary

Discussion Overview

The discussion revolves around the concept of whether the universe could be created from zero energy, particularly through the idea of a second universe with particles having opposite momentum to those in our universe. Participants explore various hypotheses related to quantum fluctuations and the nature of particle creation.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that if a second universe exists with counterpart particles of opposite momentum, both universes could theoretically emerge from zero energy.
  • Others mention hypotheses suggesting that the universe may have originated from a quantum fluctuation, akin to a virtual particle/antiparticle pair appearing spontaneously.
  • There is confusion regarding whether the existence of multiple universes is implied or if the discussion is limited to a pair of universes.
  • One participant expresses uncertainty about the possibility of creating particles with opposite momentum from zero energy.
  • Another participant challenges the idea, asserting that momentum inherently requires energy, thus questioning the feasibility of the original proposal.
  • A later reply emphasizes the need to base discussions on established hypotheses in the literature rather than personal speculation.

Areas of Agreement / Disagreement

Participants express differing views on the possibility of creating particles with opposite momentum from zero energy, with some supporting the idea and others refuting it. The discussion remains unresolved regarding the implications of these concepts and the existence of multiple universes.

Contextual Notes

There are limitations in the discussion regarding the assumptions made about energy and momentum, as well as the dependence on existing literature for valid hypotheses. The conversation also reflects a mix of speculative ideas and established theories without clear resolution.

If the creation of our universe went alongside with creation of a second universe wherein each particle in our universe had a counterpart particle in it with opposite momentum, could those universes (our+second one) be created from zero energy?
 
Space news on Phys.org
There have been hypotheses proposed in which the universe popped into existence from a quantum fluctuation - like a virtual particle/antiparticle pair spontaneously appearing.
 
@entropy1 I'm confused - are you saying there must be more Universes, not just one? Or are you asking could there be two or more?

Let's say that I pose a mirror-universe that started off as the mirror image (wrt momenta of particles) of ours. Like a pair of universes. Of course there could be any number of different universes besides that. But my point is our universe (pair). I suspect that the creation of two particles that have opposite momentum can be created with zero energy, but I'm not sure.

Why in the world would you suspect that? Do you see oppositely charging elephants popping up all around you?

Ok. That was very dumb of me I suppose...

The energy has to come from somewhere, although your idea is correct, virtual particles appear as oppositely charged pairs in our current universe. If a virtual particle big bang is your belief then an equal antimatter universe is pretty much a given.
Plus I do believe the Elephants have been shown to be standing on Turtles, not running away.

This is not possible. Anything that has momentum must also have energy.
 
@entropy1 as @DaveC426913 mentioned in post #2, there are hypotheses in the literature more or less along the general lines you refer to. PF discussion should be based on one of those hypotheses in the literature. Trying to construct your own hypothesis without being intimately familiar with what is already in the literature (a) is not likely to be fruitful, and (b) runs afoul of PF's policy against personal speculation.

If you can find a particular hypothesis in the literature that you have questions about, feel free to open a new thread on that. This thread is closed.
