Sell me a quart of gravity if it exists, it’s just math not a thing. Like the sandbox does not exist, it is a theory and effect. I don’t think there is a sandbox but the overall effects of the process gives you the impression of one.
I will bow out on this topic now. I was amazed at the amount of time spent on it, like I said at first. No offense intended. I have spent a day posting about it myself. Peace, guys. Have fun in the sandbox.
