I am no expert, but I think academic journals from, idk, google scholars, is more credible evidence than youtube videos and you should switch to those and link them here if you want to expand your thoughts.
1} Albert E makes a comment--see in my profile comments--- about his education being the biggest impediment to his learning ---learning from the experts is insuiated i believe--
2} Again, no one has offer any logical common sense critical thinking that invalidates my givens as presented in post #1.
3} sidewalkers comments infer that Gravity, space-time and any warping/bending/twisting thereof if just abstract concepts of mathematical thoughts, not occupied space,
4} Mass-attraction occurs and if it is not occupied space bosonic force of Gravity, then please explain better than Harry Cliff has done, and I trust his knowledge base as well or better than Sidewalkers, on the issues Harry disscussess,
5} Occupied space , as in' space-time ' = non-quantized, occupied space Gravity ( ) --complemented by Meta-space maths { complex maths included } ergo geometric locations aka triangulations i.e. to get a fix or caculate a trajectory etc on a location and target ---
...5a} Occupied space time, as in time in ' space-time ' = our observed { quantized } physical reality --complemented by abstract Meta-space time and again used to get exact location in geometric space---,
...5b} Occupied space, as in ' space-time ' = non-quantized, occupied space Dark Energy )( --complemented by Meta-space maths again, to this one is mostly about acceleration of the expansion or, seeming expansion of occupied space Universe.
I'm no expert either, however based on at least 100 years of knoeledge regarding Gravity aka mass-attraction we have heard thousands of time from reputable scientist that the sun and galaxies etc warp a ' something ' labeled ' space-time ', ergo photons follow this warped space-time curvature.
So continue to ask you and others what exactly/specifically is this ' space-time ', is that, can be warped/twisted/bent etc?
I believe it is kind of incorrect ---if not nutty--- to say, that, space-time is just and abstract,Meta-space concept of mind/intellect, and not occupied space something, that is bent/curved/warped and the occupied space photons around galaxies and suns etc are not following abstract Meta-space mind/intellect/concepts, rather and occupied space called Gravity, if not in some specical-case set of circumstances,
regarding the expansion of Universe, then we incur occupied space Dark Energy. Or do you Intelligence thing Dark Energy is also not an occupied space, and rather just an abstract, Meta-space mind/intellect/concept? Well do you Intelligence?
I think Dark Energy is occupied space, and may possibly be causing us in --physical reality--- to think the Universe is seemingly expanding., and Ive posted before my poor askew based diagram of how and why that scenario may be incurring.
PLease share when you have logical common sense critical thinking that adds to, or detracts from my scenarios as presented.
