Apologies for readdressing Bonzelite’s idea.<br /><br />I read through this entire thread while sitting on the toilet (over many sessions). I have found it both entertaining and frustrating. One frustration was Bonzelite not addressing some excellent questions and then not admitting he didn’t know the answers. Equally annoying was people “writing off” Bonzelite’s view of gravity because he didn’t answer those questions.<br /><br />I share the view that gravity is an illusion and not a “force”. Many questions asked in this thread are excellent, but may be nonsense in the light of a deeper understanding of the fabric of the universe.<br /><br />For instance, an expanding earth seems ridiculous in the context of our three dimensional universe. Objects in apparent orbit around an expanding earth would indeed never be able to swing around the other side of the planet in Bonzelite’s model.<br /><br />However, when the universe is understood as existing in more than three dimensions, even the question of an expanding earth and the notion of orbits may not make sense. It is likely, should we be able to see things in a many dimensional universe, the expanding earth would actually be particles (encapsulated energy) moving in straight lines. Orbits, might also be particles moving in straight lines.<br /><br />The fact that all objects fall to earth at the same speed, irrespective of mass (and yes, I know that momentum counteracts the stronger mutual attraction of larger objects), is just all too convenient. The fact that objects approaching the earth do not “experience” gravity in their frame, that objects in orbit do not experience gravity in their frame, the fact that objects in orbit are moving and yet don’t on average get further away is cause to pause and think that perhaps an expanding earth, as stupid as it sounds, is more likely to be correct than an invisible force.<br /><br />When a round earth, rather than a flat earth, was originally put forward as an idea, I am sure many of t
