Quantum vacuum fluctuation

[Jordan14]

I understand that virtual particles and anti-particles are made and destroyed resulting in what some might call a vacuum not being one. Can a physicist happen this a bit more in depth, please.

A quantum fluctuation IS the appearance of equal but opposite particles out of vacuum.

In (non-string) quantum gravity SPACE ITSELF can appear as a fluctuation

 

see "emergence of a 4D world from causal quantum gravity"

http://arxiv.org/hep-th/0404156

 

see "semiclassical universe from first principles"

http://arxiv.org/hep-th/0411152

 

these are recent technical articles

 

so yes it is true that in a vacuum, particle/antiparticle pairs can appear briefly and then very quickly be annihilated. Something called the Heisenberg uncertainty principle allows for this

 

But it appears likely that more than that is true. Fluctuation can briefly produce particles but it can also allow space itself to arise from no-space. Or so it seems according to the quantum gravity model of these authors. If you look at Figure 1 of the second linked article you will see the history of a small universe that appeared in one of their

computer model runs. They run the model repeatedly using randomness

in order to understand better what can happen in nature and how the space of our own universe may have come into existence (along with the particles also).

 

this is new theory and not much has been written in the popular press

but there are some 5 or 6 popular articles available here

http://cgpg.gravity.psu.edu/people/Ashtekar/articles.html

 

the best popular articles are the translations into English of ones originally in German by the science-writer Rudi Vaas. You will find them at the Ashtekar link given here.

 

However even Rudi Vaas has not yet written about the new articles

by Jan Ambjorn et al. called "Emergence of a 4D world..." and the other one. So the only way to read them is in the raw technical form
