Does the expansion of a quantum system of particles cause the creation of new space?

Thanks @Mordred and @Genady

Time for my bed😀

What @Mordred said, plus the better picture is them being squeezed all together into one crazy soup of elementary particles rather than torn apart.

Good night to both of you.

neither inflation nor expansion create particles, expansion and inflation occur due to particle interactions

 

 

 

Just came across this (at 30 mins 28 sec)  where Guth says that "inflation crates mass".

 

 

If true ,does the created mass create particles?

not necessarily mass is simply resistance to inertia change. The video is likely referring to thermal equilibrium and the subsequent thermal dropout due to inflation of the electroweak symmetry breaking. Likely Higgs inflation
