Round? And how did you see this 'roundness' which is not the same as spherical? Airplane window? High mountain? It is alarming that anyone still thinks water can adhere to a ball spinning a 1000 miles an hour while suspended in a perfect vacuum - a vacuum held at bay, by a thin layer of air. I would not even entertain a conversation with you about it, until, and unless you could demonstrate to me how you would accomplish all of the above.
I’m no expert on how the higher realms glue this dimension in place. Or how God makes this happen. All I know is I was able to leave the 3rd Dimension consciously and see our world and our solar system from a different perspective. I’m sharing that perspective with whoever wants to know. I think it all depends on what aspect of what dimension one is viewing from.
Please disregard my poor choice of the word round. I should have said spherical.
