The idea that the universe may have started with a quantum fluctuation

[geordief]

Have I understood this correctly?

 

Is it really proposed that this may have happened with  with a symmetric or asymmetric  balance of negative and positive "energy?

 

Any evidence or proposed experiments along those lines?

 

Quantum fluctuations don't normally "run away with themselves do They?

I believe one of my favourite link may give some idea,,,,,,,https://www.astrosociety.org/publication/a-universe-from-nothing/

So speculative

I should have known.

 

Still quantum fluctuations are not speculative and so we have to start connecting the dots somewhere.

"Quantum fluctuations may have been very important in the origin of the structure of the universe: according to the model of expansive inflation the ones that existed when inflation began were amplified and formed the seeds of all current observed structure. Vacuum energy may also be responsible for the current accelerating expansion of the universe (cosmological constant)."

I've found an old topic on this forum regarding this subject, maybe you'd like to read that discussion?

I'm a fan of this hypothesis by the way, how about you?

Is it of any consequence that energy is relative when talking of the energy of the vacuum?
