Is the universe still thought by the mainstream to be expanding at an accelerated rate?
If so, has it been considered that the following mainstream principles may play a role (I have researched and can find little of relevance):
Not acceleration, but variable deceleration - in that - if all mass is moving away from the “bang” point outwardly on various paths, then (just as the edges of a slice of pizza) they move further and further way from each other the farther out from the center. And so, bodies of mass that are closer to the “center” are closer to their neighbors (of equal distance from the center) on the neighboring path. Like wise, mass on the “edge” of the universe is the furthest away from mass on its neighboring paths. Thus, Mass on the edge of the universe will experience the least amount of gravitational pull in a “sideways” direction, as its neighboring masses are furthest away. Therefore, “edge mass” overall would be the most likely of all mass to retain a straight line movement away from the “bang” point and thus decelerate at a slower pace. And so too would each “layer” or “shell” of mass be more likely to keep truer exit paths away from the bang point, except that each layer inward will experience more and more “sideways” pull – having the effect of greater and greater deceleration towards the “center”.
From an observer’s view standing on any of the masses would not all other masses in all directions appear to be moving away from the observer? And if the rate of deceleration is greater from the edge inward, wouldn’t this appear identical to “accelerated expansion”?
I haven’t posted much here and am cautious not to present an ATMS post in the wrong place. I haven’t found much information as to whether accelerated expansion is mainstream and if so which theories are the most widely accepted. That’s why I am asking.
