You were totally demolished in the "cosmological redshift" thread on that issue. What's your answer? God?...which God? Please Register or Log in to view the hidden image! Spacetime can be said to be expanding, yes. Why? We do not really know...DE? CC? ZPE? What's your answer? God again? Please Register or Log in to view the hidden image! When exactly does expansion overcome gravity? Now that's a good question.......I don't really know. Perhaps there is some mathematical solution to that, I'm not sure. The point is though that our local group of galaxies and even beyond, is gravitationally bound and overcomes the overall large scale expansion. And it's spacetime, that expands, not space. "The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality." Herman Minkowski And of course as origin has said just above, the expansion of spacetime is a result of GR: GR works and works fine,eg: GP-B, and aLIGO attest to that fact. To deny the obvious, is well, rather strange shall we say. And of course as I'm fond of telling you, it is your right to sprout whatever nonsense you see fit, and it is your right to avoid any pertinent questions anyone puts to you, but irrespective of all that, academia and mainstream remain as robust as ever. You do understand you make no difference with your nonsense, right?
