when a phenomenon is explained, that means the proposal may indeed be the explanation. what it requires, is fewer assumptions than the opposition. as my proposal requires none, as we know space exists, and the rest is a logical deduction of that fact, that means it should be accepted.
at the very least, you must concede that. the only thing i can imagine you're questioning, is my deduction. however, your responses have been no more than assertion.
heat is not 'attached' to matter, as that implies it has some material existence. if you believe the sun's heat reaches us through a vacuum, then that is not true. heat exists with no matter: and it still exists in different concentrations. this is all a simple fact.
i do not possess the means to cut spacetime. if you would like an example, even in round earth theory, of things beng drawn towards gaps in space, however, i can happily oblige: black holes. my theory simply explains why that occurs, rather than handwaving and saying no more than "this is what we observe," with no answer for the crucial why.
