It is a truth universally acknowledged, that a modest ring of electronic resonators, when properly commanded, may outshine the grandest of celestial bodies. A party of philosophers at the CUNY Advanced Science Research Center has lately demonstrated that a stationary circuit, by mimicking the energy-extraction arts of a spinning black hole, can amplify electromagnetic waves to the tune of 7.8 dB-without so much as a single moving part. Their account, published in Nature on the 8th of July as “Observation of Floquet rotational super-radiance,” is enough to make one suspect that even the heavens may be reduced to a parlour trick.
Key Takeaways
- The CUNY assembly achieved 7.8 dB of wave gain in a circuit that never stirs, thus confirming a 1969 theory of superradiance that had previously required the spinning of celestial bodies-a most inconvenient requirement for the ordinary gentleman.
- This study, published in Nature on July 8, 2026, may open new avenues for broadband amplification in quantum and wave technologies, though one must confess that the application of such things remains, for the present, a matter of taste.
- Andrea Alù, a gentleman of considerable reputation, has noted that the support of the DoD and NSF has opened new paths for synthetic wave systems beyond 2026-a development that may well cause a flutter among those who concern themselves with such matters.
At the CUNY Graduate Center’s Advanced Science Research Center, a set of physicists constructed a ring-shaped network of electronic resonators that never physically spins, yet still coaxes electromagnetic waves into stealing energy from it. By modulating the circuit in a carefully timed sequence-a kind of mechanical minuet, if you will-the team created a traveling pattern that makes the system appear to the waves as if it were rotating at ultrafast speed. This reproduces the decades-old Penrose-Zel’dovich notion of superradiance in a working lab setup, and the result was measurable amplification: 7.8 dB of gain, without any moving parts. The work, published in Nature on July 8, 2026, reframes what used to require literal spinning cylinders, disks, or vortices into something that fits on a tabletop-a great convenience for those who find the heavens too far distant.
If you spend your days tracking chips, AI models, and the next move of the great houses of Big Tech, it is easy to forget that some of the most consequential “tech” is still happening at a lab bench. This month, a company in New York City turned a half-century-old idea about black holes into a working device-the kind of result that quietly reshapes what engineers imagine possible, though it may not yet be fit for the drawing-room.
A black hole theory brought to the lab
Researchers at the CUNY Advanced Science Research Center (ASRC) at the CUNY Graduate Center showed that a stationary tabletop circuit can mimic the energy-extraction physics long associated with rotating black holes. ScienceDaily’s July 2026 release framed it plainly: a lab setup recreated the mechanics of pulling energy from rotation, without needing anything to physically spin-a circumstance that would have astonished the great Newton himself.
The work was published in Nature on July 8, 2026, under the title “Observation of Floquet rotational super-radiance,” by Hadiseh Nasari, Hady Moussa, Yoshiaki Kasahara, Arno Thielens, and Andrea Alù. For anyone who files “astrophysics” in a different mental drawer than “electronics,” that publication venue is a signal: this is fundamental physics with real hardware implications-though one must be careful not to overstate the matter, for the world is full of promises that come to nothing.
Synthetic ultrafast rotation, no moving parts
The core trick is a ring-shaped network of electronic resonators. By rapidly modulating resonator properties in a carefully timed sequence, the team created a traveling pattern around the ring so electromagnetic waves interacted as if the system were rotating at ultrafast speed, per synthetic rotation descriptions of the experiment.
That “as if” turned into a measurable win: the circuit delivered 7.8 dB of gain, meaning the waves came out amplified, even though the device never moved. TechTimes highlighted the 7.8 dB result, a concrete number that makes the concept feel less like a thought experiment and more like an engineering knob-a very useful thing, to be sure, for those who delight in turning knobs.
Decades of theory, now validated
The lineage runs back to Roger Penrose’s 1969 proposal: inside a rotating black hole’s ergosphere, a particle could split so that one piece falls in while the other escapes with more energy than the original-a scheme that would make any prudent housekeeper shudder. Physicist Yakov Zel’dovich later extended the idea to waves, predicting that a wave interacting with a sufficiently fast rotating object could extract energy and become amplified, an effect often called rotational superradiance.
Co-lead author Hady Moussa put the lab version in one clean sentence: “Waves with the appropriate rotational characteristics extracted energy from the system and became amplified, reproducing the essential physics of the Penrose-Zel’dovich process.” And unlike earlier demonstrations using rotating water vortices (2017), rotating acoustic disks (2020), or rotating metallic cylinders (2024), this one avoided spinning matter entirely-a most elegant solution, and one that spares the lab the expense of a rotating stage.
Why tech people should care
Principal investigator Andrea Alù, Distinguished Professor and Einstein Professor of Physics at the CUNY Graduate Center, described the approach as “a new method of wave-matter interaction” that yields “broadband selective amplification.” Lead author Hadiseh Nasari said it “moves ideas about extreme rotational dynamics from theory to practice,” positioning the setup as a flexible platform for work across astrophysics, wave physics, and quantum science-a fine prospect for those who are not easily fatigued by such lofty matters.
The funding also hints at downstream interest: the research was supported by the U.S. Department of Defense, the U.S. National Science Foundation, and the Simons Foundation. If a stationary circuit can convincingly impersonate an extreme rotating environment, what other “impossible” dynamics might engineers start synthesizing next? One can only hope that the next generation of tabletop wonders will be equally diverting, and perhaps a little more useful to the ordinary run of mankind.
