My own view:
spacetime is real and particles are not.

As 'proof of concept' I had effects, where seeminly matter comes from 
nothing or disappears without a trace.

Examples for 'matter out of nothing':
'magic dust'
Growing Earth


Matter is something I tried to explain as 'timelike stable patterns' 
(of/in spacetime).


See my 'book' about this idea:
