@drbecky_s: What’s going on at the Moon’s south pole?! The south pole is heavily cratered, more so than the rest of the surface of the Moon. It contains the largest structure on the Moon known as the South Pole-Aitken Basin, it’s 8km (5mi deep) and spans roughly 2,500 km (1,600 mi) in diameter from the craters at the south pole to the Aitken crater at the top, with a chain of mountains ringing the edge. It’s one of the largest craters in the solar system, and underneath it is where the GRAIL mission found the Moon’s gravity was much stronger than it should be. The data suggested there’s something really dense beneath the Moon’s crust that’s roughly five times the mass of Hawaii’s entire Big Island. It’s so dense that it’s pulling the basin floor downward by almost a kilometre. So what could this mystery density be? And will NASA's Artemis mission help us answer this question? 👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford. I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars. #moon #artemis #nasa #Science

If the moon was formed from two mini plants colliding that made earth, couldn’t it be possible that one of their dense cores didn’t get stuck to the young earth? Especially if they hit each other at a near tangent angle, I’d expect the small planet to just keep sliding after knicking the big planet and for a cross section of the small planet to escape into orbit. Then there’d be the more dense core fraction exposed on one side and a less dense crust on the other and it’d just have to smooth out as it collects more debris to form the moon

Imagine that your job is measuring the gravity on the moon from orbit...

Good day! I’ve developed the Bahinting Releasation Theory to solve the information paradox using a 1.0 Equilibrium. My model treats black holes as 'lossless processors' that reformat matter into encoded radiation at the Planck limit. By applying Landauer’s Principle, I'm showing that identity is never deleted—only preserved through a frequency shift to maintain Quantum Unitarity.

Well, of course there’s a super dense object at the south pole. It sank to the bottom! 😁
