There may be Gravitational Lensing in this picture.
Well, as best as you can Observe.
The symmetry is a clue that points to that.

Flying Without a Rudder
Aircraft typically use a vertical tail to keep the craft from rolling or yawing. Birds, on the other hand, maneuver their wings and tail feathers to counter unwanted motions. Researchers found that the list of necessary adjustments is quite small: just 4 for the tail and 2 for the wings. Implementing those 6 controllable degrees of freedom on their bird-inspired PigeonBot II allowed the biorobot to fly steadily, even in turbulent conditions, without a rudder. Adapting such flight control to the less flexible surfaces of a typical aircraft will take time and creativity, but the savings in mass and drag could be worth it. (Image credit: E.

*I am somewhat dubious of this date because a) I was trained to use the metric convention day/month/year and b) physicists use the reduced constant h-bar (that’s h divided by 2 pi) and then, cause it’s easier they just change units such that h-bar = 1 but it’s as good an excuse as any

Happy #QuantumDay, everyone! 
Discovering #quantumtheory revolutionized #physics forever - and might even make your hair stand on end! 
#MaxPlanck
If you stumble upon #Physics papers even a little related to HEP, and it isn't on @inspirehep.net, please submit it! @cern.bsky.social adds it with 1-2 days and then everyone benefits from the shared BibTex labels. I still find papers by folks like Dirac or Wheeler missing!

Neutrinos' maximum possible mass shrinks further
https://www.sciencenews.org/article/neutrino-mass-shrinks-katrin-electron
Science News · Neutrinos’ maximum possible mass shrinks furtherThe KATRIN experiment in Germany nearly halved the maximum possible mass for neutrinos, setting it at 0.45 electron volts.
Splitting water into hydrogen and oxygen takes more energy than it theoretically should, which is partly why it's not used on a large scale to generate hydrogen fuel.
Now scientists know why – and it's all down to a feat of nanoscale gymnastics.

Curiosity Meets Science – Girls’ Day 2025 at #MPL & #MPZPM
We recently welcomed 30 curious girls to explore #physics, light, and #medicine at our institutions. They discovered the daily work of physicists, lab engineers, mechanics, and IT’s role in #research. With countless questions they explored labs and workshops. We hope to inspire future #science and #technology enthusiasts!

Never challenge #physics, because there's no guarantee it works as you think.
If mathematics is functional vision in a cosmos of energy and momentum, what abstract practice is it that allows us to perceive and process the deeper messages woven into what we see through proof & calculation?
The infinities, the limits, the bumpy smoothness, the funhouse symmetries (maybe real?), the utterly confounding illogical puzzles…
We are VERY excited to run the @snolabscience.bsky.social #UndergroundScience Institute #Lecture Program for its second year. Grad students and post-doctoral researchers are strongly encouraged to submit applications of interest.

Another version of the "tomato battery" experiment, in a somewhat cleaner home setup. 
Sadly, a few cherry tomatoes were harmed during the process - they really cannot be eaten after this process, since copper is deposited in the solution!
Reclaiming the Land
Lava floods human-made infrastructure on Iceland’s Reykjanes peninsula in this aerial image from photographer Ael Kermarec. Protecting roads and buildings from lava flows is a formidable challenge, but it’s one that researchers are tackling. But the larger and faster the lava flow, the harder infrastructure is to protect. Sometimes our best efforts are simply overwhelmed by nature’s power. (Image credit: A. Kermarec/WNPA; via Colossal)

Science News · More details about the Myanmar earthquake are emergingA phenomenon called liquefaction, which causes the ground to slump like quicksand, led to significant damage after the Myanmar earthquake. The risk of aftershock remains high.
Physicists have confirmed a new mismatch between matter and antimatter.
Science News reports: "Charge-parity violation occurs in a class of particles called baryons."
Science News · Physicists have confirmed a new mismatch between matter and antimatter Charge-parity violation is thought to explain why there’s more matter than antimatter in the universe. Scientists just spotted it in a new place.
