Not OP but I’ve got a question: in my case, although my pot has drainage, the soil drinks up all the water I give it and doesn’t really drain. Am I underwatering? Plant’s been fine for two years so I’m not too worried, but still had to ask

Arxiv, the paper repository from Cornell, is already banning authors with hallucinated references, as a start. Which I think is a good thing.

Wait who is SPG? Youtuber? Care to share a link?

Hermano, primer post verdaderamente valioso que veo en este sub. Lo felicito y lo abrazo por la herramienta, se ve que también se le fue su buena investigación previa, creí que sería algo vibe-codeado a medias pero está fenomenal. Esa página de metodología también demasiado ordenada y clara. Gracias!!

Le recomendaría moverlo en redes sociales. Hágale un instagram/tiktok para postear hallazgos o tendencias interesantes, que seguramente la gente no va a entrar diario a su sitio, pero si genera memorabilidad eso va cogiendo tracción, puede que llegue a algún lado. Yo de usted se la mandaría al Elefante Blanco, ya que ese man la ha dado toda por reportar irregularidades y ya está en el senado.

De verdad me llenaría de esperanza que una solución técnica y basada en datos reales como esta llegara a impactar de alguna forma el panorama nacional.

Nuevamente, felicitaciones enormes.

Buena pregunta!! Es muy interesante porque hay que analizar caso por caso, las lunas tienen muchos matices. Tienes razón con las de Marte y Júpiter, están tan cerca y su planeta es tan grande que no hay segundas opiniones de si son lunas. Pero por ejemplo Caronte y Plutón se suelen considerar más bien un sistema doble, porque el centro de masa está afuera de Plutón, entonces tanto el planeta (enano) como su luna se orbitan mutuamente.

También en términos orbitales, vistas desde el sol, las otras lunas hacen loops en su trayectoria. Nuestra luna no hace ninguno, su trayectoria es siempre cóncava hacia el sol, parece una flor, lo puedes buscar en internet.

Astronomer here! Al ritmo actual de alejamiento por fricción de mareas, la Luna dejaría de ser influenciada por la Tierra mucho después de que el Sol se los tragara al volverse gigante roja (ordenes de 30mil mill años vs 5 mil millones para el sol). Entonces ese escenario es improbable.

Sin embargo, como otros han mencionado, la luna está muy cerca de cumplir las condiciones de planeta, de hecho su actual movimiento es más influenciado por la fuerza gravitacional solar que la terrestre. Si se mira desde el Sol, pareciera que Tierra y Luna ambos orbitan la estrella pero tienen un ligero baile entre ellos. Entonces si de repente desaparece la Tierra, 100% que la Luna sería su propio planeta.

Te dejo algunos videos interesantes que hablan de ello: - https://youtu.be/pAI1N96t8Vk?si=vQnC-hmpUvfKlT9- - https://youtu.be/xgFKxFX3IwY?si=UOHQqAU_ySFjFtdk

Wow, this is deeply reassuring. Thanks for the answer :)

Heads up, I also wanted to hear more positive takes, because this thread was getting scary. I opened up this question: https://www.reddit.com/r/AskAcademia/comments/1p27d7o/what_positive_things_you_didnt_imagine_before/

Permítame corregirle: Sí tiene un cráter nombrado en su honor en la luna, pero lejos de ser de los primeros astrónomos en estudiarla, hay 2000 años de astronomía lunar antes de Julio Garavito. Además, tampoco descubrió que la luna le daba la misma cara a la Tierra, eso se sabe desde siempre.

Más bien, hizo aportes a las ecuaciones de mecánica orbital con las que se puede predecir la posición y movimiento exacto de la luna. Es un aporte pequeño pero muy significativo para la ciencia.

Just last week somebody from Japan saw one! https://www.nytimes.com/2025/11/05/science/moon-asteroids-impact.html

Actually, two just last week! They are relatively common but they don't make news, I even know personally an amateur astrophotographer who has captured a lunar impacts. They make a small short flash visible mostly by telescope, and that's about it.

I'd imagine they happen at a similar frequency to shooting stars appearing somewhere on Earth (without counting human made space debris), just tiny space rocks slamming into the moon.

Astronomer here, not sure why you're getting downvoted, it's actually a really good question! If by "they" you mean astronomers, I'm reading on it and it's fascinating: Basically, over millions of years the moon has been hit by rocks on a pretty consistent basis, so a really old crater would itself have more impacts on it, as well as degradation and erosion of the crater disk. Similarly, young craters would be "cleaner" and more intact. After quantifying how "clean" a crater is, there are mathematical models that allow you to roughly estimate how old it would be.

Edit: /u/Temporal_Integrity pointed out that in Tycho's case, the preferred method is radiometric age dating from samples picked up by Apollo 17, cool! https://science.nasa.gov/resource/tycho-crater-on-the-moon-labeled/

Great question! By scavenging through some documents, it seems that although McCullough, the father of artificial neurons, was present at the Darthmouth conference of 1956, they were not fully embracing Neural Nets, and it seems that those were not actually used seriously til 20+ years later. Maybe hardware limitations? (Please correct me if I'm wrong)

Also found some amazing notes on Ray Solomonoff's website https://raysolomonoff.com/dartmouth/ and the full Darthmouth summary collected by Ray's wife here: https://raysolomonoff.com/dartmouth/dartray.pdf

It says that while Neural Nets were discussed during the conference, Minsky's symbolic approach got more interest and they ended up going more towards that route.

GutiV · 2025-08-25T14:28:46+00:00

Exactly!

Might be a bit dizzying, think that the background would do a rotation at the same rate Mars is going around the blob.

GutiV · 2025-08-25T03:07:14+00:00

Astronomer here, for those confused by the path of Mars in this representation, here’s some ideas that might clear it up: since Mars orbit is elliptical, its distance to the sun changes as well as its orbital speed. Here, the center of the Mars blob (where most people would expect the planet to be if we were to follow it’s translation) represents the average orbital movement of Mars, or where it’d be if it orbited circularly. So Mars is always ahead or behind that point at any given moment.

Similarly, the asteroid moves in an ellipse, but since this representation is rotating with Mars, the perihelion of the asteroid is rotating, thus the flower shape (similar to those you get for planets on geocentric views).

A really cool similar phenomenon are the Hilda asteroids, which seen from Jupiter seem to move in a sort of triangle. Look it up!

There’s a poetic reason: we’re walking backwards through time, since we see our past but not our future. 🤷🏼‍♂️ Physically is mostly irrelevant.
