I was doing a little research

After watching a few videos of UAPs “changing shape and morphing in the skys, I had to wonder if there’s any tech they’re claiming is being “currently worked on” that would, if perfected, explain this kind of thing. Sure enough, yes there is. Nano-infused black gel, a very real thing that is self healing and being developed with a view to use it in spacecraft, among other things. It can also be engineered to change shape, move, or reconfigure on command. This is an active area of research as a whole, called programmable matter. We are talking smart materials, and shape-morphing materials that could help us create spacecraft so advanced they appear “alien” to us.

Some polymer gels can be “programmed” with a shape and then triggered to return to it later.
And I firmly believe that our real technological ability as far as that which is used by various military and government organisations and so on, is decades ahead of what they claim we are capable of producing.
If they say they’re working on it, they perfected it ages ago.
Just what I think, anyway…
