I am moving my discussion of something from nothing over here from religion. I put it under metaphysics because something from nothing is no more provable or testable than religious creationism. If there is no possible experiment then it can’t be science, at least by Popper’s definition. Some considered String Theory philosophy for the same reason.
Non-Exiastence - No mass or energy or causation
Something From Nothing - Mass and energy appearing or manifesting in our reality out of non-existence without any causality, the appearance of mass and energy.
In the 90s Hawking wrote he could prove the universe cod create itself out of nothing which resulted in a religious response.
Something from non existence’ to consistence is analogous to creationism regardless of who proposes it, scientific credentials or not.
Continuing from the other thread, There is nothing that says a virtual particle comes from any kind of ‘non existence’.
I looked at virtual particles years back on the science forum.
After looking at it again I get the same conclusion.
It is interpretation and semantics. To me it looks like a gap filler in a partcle process. Part of a Feynman diagram. There is nothing wrong with that. A working thory does not have to reflect reality exactly, it has to predict measurable outcomes.
With capacitance Maxwell was faced with a dilemma, a capacitor is an open circuit so he had to resolve it Kirchhoff current law, essential conservation of energy, and Ampere’s Law. He came up with displacement current to resolve the issue.
A photon can be said to come to being from non existence. A photon does not exist at rest and goes out of existence when absorbed., but not from otr to nothing.
Run a current through a wire antenna and locally there will be a jumble of electric and magnetic fields but no propagating wave uf photons with orthoganal electric and magnetic field. This change from one state to the next can not occur nstantaneously, even particles.
Nothing happens in zero time, as dt goes to zero you end up with a divide by zero and an infinte asymptote. If something comes from nothing is it instantaneous? If so what is the energy required? Or is it a lossless process.
No energy and mass and no causation is what I call magic. Abracadabra and a particle appears and dispears.
A sequence of particle creation and extinction can not be instantaneous unless you want to dispense with causallity and C as a limit.
