I usually view the word "world" to mean just this planet Earth. You may want to mean the Universe... and still you may be wrong and it may be possible to create matter and energy. Space-time (which can be the same as saying 'nothing') creating particles is a thing that won some guy a Nobel Price some time ago:
https://en.wikipedia.org/wiki/Quantum_foam Wrote:Quantum foam or spacetime foam is a theoretical quantum fluctuation of spacetime on very small scales due to quantum mechanics. The theory predicts that at these small scales, particles of matter and antimatter are constantly created and destroyed. These subatomic objects are called virtual particles.[1] The idea was devised by John Wheeler in 1955.[2][3]
I meant "World" to mean all of the universe and not just the Earth. Theoretical quantum physics is well beyond my level of understanding. For my purposes I am comfortable with the Laws of the Preservation of Mass and Energy. It may be too simplistic to deal with spacetime foam but I have never really dealt with spacetime foam.
