 It's interesting how most physicists describe spacetime
as an actual "fabric."  It's really a mental model that
may not have any existence at all.  The equations of
relativity describe what actually happens quite well,
but the "fabric" of spacetime may be an invention.
 I think the things that are real are THINGS.  I find the
basic concept of string theory very compelling: that is,
elementary particles are not points as the standard model
posits.  In the real world there are no such things as
dimensionless points.  It's a very good assumption because
the string theory particles are way smaller than we can
detect, but presuming elementary particles have extension
in space is surely correct, even though strings may not be.

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:
