Wouldn't it be cool if the micro antennas could be altered in situ to produce a completely solid state zoom lens?
An update on this matter.

Due to the compact size, metasurface can be wildly used in augmented reality (AR) [158–160], virtual reality (VR) [161], and light detecting and ranging (LIDAR) [156, 158, 162, 163]. To explore more capabilities, the bilayer metasurface is introduced to explore the capabilities of greater manipulation, that can’t be generated by the single metasurface. Inverse design based on optimization algorithms or machine learning is also introduced. Inverse design helps us achieve unique metasurface performance, especially those problems that cannot be solved intuitively by traditional design methods. How to develop the inverse design algorithm fast and precisely remains the research hotspot [164, 165]. However, traditional metasurface is passive. A dynamic and compact optical element is appealing. By integrating the metasurface with LCs, digital micromirror devices (DMD), spatial light modulators (SLM), or other dynamic devices [166]. To further minimize the size of the system, phase-change materials are introduced. They can change their optical response under electrical, thermal, mechanical, and light stimulation [167, 168]. The spatiotemporal metasurface can achieve more capabilities.

Are you serious? Membership in that group is, I guess, the thing that's most strongly correlated with making money off the ritual. Hence the information content of their statement is close to zero. I would put them in the category of every other group that's about to lose an existing source of income and trying to prevent that. In terms of bias, that's where the most aggressive lobby groups are to be found.
[eta: never mind. That was probably sarcasm failure on my part.]
I read the explanation when I first saw the video. I'm no rememberator, but I call it explosive rebound. Some portion of the explosive force pushed downward through the can, hitting the solid floor beneath and then reflecting enough of the remaining energy back into the can causing it to lift off the ground like it did.
I'm sure we have a scientist on staff who can tell me how wrong I am.
That really sucks. The article depressed me a little.

If that happens, then truer words were never spoken. I can't help but think our last few generations have done a damn good job of fucking over the planet.

It is interesting to note that it wouldn't take that many qbits to compute the universe. On the order of a thousand. It's almost recursive in that it appears the universe is basically quantum and quantum computers of modest size could in theory compute the universe.

No, quantum computers of modest size can simulate quantum systems of modest size. So maybe, maybe you could simulate a classical version of the universe (of course there is no such thing) but you can't get most of the answers out (you only get to measure once). To simulate a universe of qubits, you need a universe of qubits. Or more time. What you can get rid of is the exponential slowdown, which is huge.
Always wondered about that, but never been very good with the Math.
I mean, after all, velocity is always relative, right? And, then there is the whole Time Dilation thing.
I reckon it will be a few more years before we can get any meaningful data on all that.
Suppose I won't get to see it.
Now, I'm REALLY bummed.
