So time is like a constant spring being sprung, and you can't go back in time to unspring the unleashed forced cuz the asymmetrical shape of the universe (with time being the arch of reality) is, and can't let matter flow backwards against the wave power formation.The nature of the flow can't let the energy go forwards and backwards simultaneously. (It's like cylander that goes through a circular hole,  and once through then expands into a star-shaped rod, and now doesn't fit backwards..the transformation is matter chain reacting through the universe and changing energy levels...Electrons don't flow backwards out of certain bonds regardless of theoretical theories of time equating the act feasible). This is the micro vs macro, infavor of micro theory strain of thought on the array of time travel relevancy.<br><br>In short that is why i assume Cronin believes time travel is not possible.<br><br>Interdemensional physics is a conversation seperate of this as it pertains to out of time phenomenon, as in out of this universal construction...Literally i think interdemensional pathways/openings/bubbles are basically a whole universe opening next to "our base reality/universe". Also for base synchronization to manifest between each of the planes of perspective, both universes must be out of time continuously with their own contiguous realms of existence  ..if of course that is at all possible hahaa... these are the conversations I'd live and die for! 🤙<br><br>I wonder if the aether and time are of similar properties and material..both massless but still ever-present.
