Just in case of any misunderstanding, there's no suggestion of liquid water on or near the surface of the Moon. Some craters near the Poles where sunlight never reaches and temperatures are close to zero Kelvin are believed to contain large deposits of ice. These deposits may be available for use by lunar bases. Water also exists in chemical combination with other matter in some locations.

Sabine, your channel is one of the places I consider “home”

[johnmichael]

Dr. Hossenfelder, you are the perfect combination of professionalism and humor. Those of us who really study physics know that you are an entirely different calibre of intellect than these popular physics personas like Neil DeGrasse Tyson and Michio Kaku. You're the real deal, and yet you manage to maintain levity and clarity in your discussions and explanations. Exactly what we need to repatriate the study of physics with brilliant young minds for the next few generations. Thank you immensely for all that you are doing for the education of the masses. You're making physics fun, which is perhaps even more impressive than your top-tier acumen in the field.

These days I eagerly wait for Sabine's new videoes to come out. And, they have not disappointed me so far. Thank you, Sabine! Keep up the good work.

Quantum bound photons, what an idea! I'm retired now but have practiced many spectrometric techniques over the years and have never considered the possibility. I wonder if it is somehow related to RAMAN spectrometry, but in reverse. Thank you Sabine for always including references to papers cited.

"A superlattice is not to be confused with a superlettuce - that's how Liz Truss plans to return to power." One of these days I'll be prepared for Sabine's stand-up comedy, but today, my sides are in orbit.

[KeithCooper-Albuquerque]

Thanks for another great video, Sabine!

[mozezo]

That's great to watch this news with your explanations .I think you give a simple and creative explanation for the material.

[windywednesday]

You are the best science news out there! You are quick, concise, and easy to understand. You cover a lot of area in a short time, accurately and you're funny.

[bobwasilewski]

I can't say it better than what John Michael posted. Thank you for all that you are and do. I see that you were born in 1976, two years after I graduated high school. During that time, you have mastered Theoretical Physics, and a number of other disciplines. Also during that time, I have mastered the use of a variety of can openers. I also used to be able to dress a bed sheet with Hospital Corners. Hey, we all have our abilities. But seriously, thank you for being you.

6:55 eigenfunction, gauge, eigenvalues, potential, well, lowest state, membrane, hamiltonian, shrodinger time equation, psi, psi derivative, quanta, constructive, probability, chromodynamics, couple, entanglement, uncertainty principal, cavity radiation, hall radiation, majoramas etc. So yes a photon is a quanta. But a quantum photon is a very specific quanta of a photon. Nice, good job Sabine for talking about this paper.😊

[Steve-Fish]

If you orbit the moon it sync's up perfectly with the wizard of oz, not a lot of scientists know that.

[AFewSmallFish]

Sabine, I really appreciate you always posting your new videos right at my lunch time. Very thoughtful of you 😉

[AlanTheBeast]

I liked the implantable fuel cell's operating logic: when the glucose level triggers it, it releases insulin causing the device to eventually stop. Very straightforward - like a thermostat. Question: how does the insulin get "in"?
All jokes asside, having an app to monitor its workings is a fine idea. Just needs appropriate encryption/access control.

[TimpTim]

Getting to a point where I'm less concerned about mind controlled robots and more concerned about robot controlled minds.

[helmutzollner]

Interesting developments, especially the implant fuel-cell. That opens a lot of new opportunities once it is working properly.

[ArjenHuizingaNL]

Lived the ME/CFS Healthcare terror with my ex for decades. She got depressed because doctors kept telling her it was a problem between her ears. Lost her job, etc. Even without a cure, acceptance will already be a big relief..

The theoretical underpinning of material sciences is, I suppose, band gaps and holes for electrons to fall into. An understanding of crystallography would be helpful.
The growth of porous single crystalline-like monoliths ( PSC ) is difficult; but using two different lattice orientations they can still get good photoelectrochemical properties. For example, band gap engineering introduces Titanium3+ gap into the lattice to generate TinO2n−1 with Magneli phase, so the created active structure can be limited to the lattice with two-dimensional surface.
Independent PSC-like ( porous single crystalline ) TinO2n−1 delivers high photocurrent of 1.8–5.5 mA · cm−2 at room temperature and does not decay for 10 hours, a Chinese group has found.
It would have to be the Chinese, of course...because of the massive research defunding in the West. It will be the Chinese who develop economic hydroysis and photocatalysis and solar energy conversion...and get that base on the Moon, if one isn't already there.
Mars is a different proposition...and it's not certain a human carrying craft could take off from Mars.

1:40 if you listen carefully to the end of the song “Eclipse” (the last song on the Pink Floyd album _The Dark Side of the Moon_ ) you will hear Gerry O’Driscoll (doorman at Abbey Road Studios at the time of recording) saying “There is no dark side in the moon, really. Matter of fact, it’s all dark.”

Thank you ....thank you for being here....thank you for caring enough to do this!
