I'm pretty sure I just learned something. I'm welcome.

Sweet! You are on the right path, IMO.😃✅💯👍🏻 Optical tweezers, Arthur Ashkin, et al, that whole thread of physics, was a big starting anchor for me in around 2012 when I first became enamored with light-matter interaction in a gravitational field. It wasn't long before I bought Fundamentals Of Photonics and started reading it cover to cover, a heavy lift for a middle aged boomer long out of engineering school, perhaps driven by what became a passionate interest bordering on "obsession". I don't suggest you do that necessarily, but you are triggering memories of a certain time in my life, still ongoing, and you just don't forget the very early days of such things. The notion of "optical tweezers" was a major inspiration. I have not regretted that rabbit hole one bit, to say the very least. 🕳️🐇🛸 All I can say is, follow where it leads you. There may be Cheshire Cats involved and it may take a while, but keep going. That book led to the most recent one, which I can not say I read as thoroughly, because now I follow this stuff daily, but that is where the whole thing is going. It gets off the ground, literally, with this. IMO. 😎

Everything is made of the smallest matter! Even the photon is made of an arrangement of this matter! Therefore, the flow of such a matter will always be subject to a flow law! The only question is to what extent we are currently able to measure it!

Is this how the orbs were held in position?
