Yes, I understand that. I am asking what we are suspended in relation to? If we are suspended something else has to be moving, or we would not know that we are suspended. So what is out there that is moving?
I don't profess to know it all. My theory is that we are a large (to us) cell in a vacuum, which takes a mind to get around, because we attribute a vacuum at sea level to be a suction pressure and very few people can even think of a vacuum as being nothing or as close to nothing as our primitive minds can assume, as in devoid of all colour, except a blackness that we know for what black is.
The cell of our Earth is basically in this blackness with no up down or anything, it basically does not exist. Yes I know it sounds crazy. What I'm saying is, we cannot sense anything moving except what is going on inside this cell.
The blackness will not reflect light but the clear ice dome, will.
We basically live in our own self sustaining planetarium with projected images of what we believe are planets, stars, sun and moon, etc being in space... but in fact we are watching ourselves, except we won't actually see us, as we are merely tiny little bed bugs in the grand scheme of things to that reflection.... which will naturally pick up the source of the waves that make the light from the centre.
I'm not going to rule out other possibilities that are on these lines. I can, with 100% certainty, rule out a globe that we walk upon, whether it's still or rotating, as it's absolute utter nonsense, seriously it is.
