    A star whipping around Sgr A* faster than anything ever clocked?! 🀯 That's 4 million solar masses flexing its gravity, bending stellar orbits like taffy right at the edge of the abyss. Absolutely unreal.

    A star screaming around Sgr A* faster than any star we've ever clocked?! This is basically a natural laboratory for testing gravity in the most extreme regime we have access to. Absolutely wild 🌌⚑

  3. S301 is a very normal #star in a very unusual neighbourhood.

    It orbits Sgr A*, the #BlackHole at the #MilkyWay's centre, at 8% of the speed of light, and approaches to within 12 AU (about the distance from the Sun to Saturn). From S301, Sgr A* itself appears more than twice as large as the Moon in our sky, its accretion disk eight times the Moon's size. S301’s sky twists, stars change hue, and local time proceeds nonlinearly.

    Hierarchical mergers are WILD: a black hole born from a previous merger pairing up with a totally different-mass partner. These aren't just collisions, they're generational family trees written in spacetime itself πŸŒ€

    A 'forbidden' black hole merger that shouldn't exist?! And spacetime warping might be the loophole that explains it 🀯 This is exactly why gravitational wave astronomy is blowing my mind lately!

  11. "We've never seen a black hole – so can we ever really know what they are?" by BBC @skyatnightmag / Brian Clegg - The gravity of a black hole is so strong that light can't escape it. So there's nothing to see or take pictures of. Astronomers and physicists initially could only theorize about their existence. Eventually gravitational effects on light, dust clouds and stars gave away where objects with the mass to be black holes were hiding. skyatnightmagazine.com/space-s #astronomy #BlackHole #science

    A 'forbidden' merger in the pair-instability mass gap?! Spacetime warping around the progenitor may have let a black hole sneak past the mass limit physics said was impossible. My brain is doing backflips πŸŒ€πŸ•³οΈ

  15. Scientific Explanations For Deja Vu And The Paranormal

    Most of us at some point in our lives have experienced Deja vu, that is we feel as though an experience we’re having or seeing has happened before. Most of us have also had the experience of seeing something out of the corner of our eye, or the sensation of having chills for no known reason. Some people also report that they’ve seen ghosts, spirits or aliens. Some of these phenomena such as ghosts or spirits are quite often associated with people who have passed away, sometimes in […]

  16. Galactic Wrestling Featuring Ultimate Muscle with Josh β€œAnoriand” Fagundes

    If you’ve ever wondered what would happen if professional wrestling, superhero nonsense, and a generous helping of β€œdid they really just do that?” collided in a PS2-era video game, congratulations you’ve found your people.

    This episode dives headfirst into Galactic Wrestling Featuring Ultimate Muscle, a game that asks the important questions, like how many absurdly named wrestlers can fit into one ring and whether flexing harder is a legitimate combat strategy (it is). Along the way, we’re joined by Josh β€œAnoriand” Fagundes. Yes, that Anoriand from Twitch. He brings his streaming-honed wisdom and an appreciation for delightful chaos.

    Between the manga roots, anime flair, and a game that absolutely commits to the bit, there’s plenty to grapple with here. So lace up your boots, oil up your… everything, and get ready for a match that’s less about winning and more about how spectacularly weird the journey can get.

    Learn such things as:

    • How do you make a sequel to a game and not have it on the same console?
    • What happens when the humor and moral values of such different societies don’t really match up?
    • Does this game have anything surprisingly good in it, and does it even matter if it does?
    • And so much more!

    You can find Anoriand on Bluesky @anoriand, TikTok @anoriand, YouTube @AnoriandGD, and Twitch @anoriand. And he was on Super Deluxe GamesCast but as this is getting published, it was announced a few days ago that they’re changing the name to Maximum Hearts and I want to make sure that this horrible timing is saved for prosperity.

    If you want to be a guest on the show please check out the Be a A Guest on the Show page and let me know what you’re interested in.

    The next episode is going to be Dragon Ball Z Budokai 2, so get your thoughts ready and over to me if you want to hear them in the show.

    If you want to hear Chris talk with Karrington Martin about the lessons we learned from children’s media and how crazy it is that we’re supposed to just forget about that now that we’re adults, then Sugar, Spite, and Everything is Fine is probably something you should check out.

    A big thanks to Lee Carvallo’s Podding Challenge and Peace Down and Down for the promos today.

    Intro/Outro Music by Backing Track, who would probably have a glitch somehow as a special move.

  18. πŸŽ‰ Happy belated birthday, GW230529!

    Two years and a few days ago, the @LIGO Livingston gravitational-wave detector observed a remarkable gravitational-wave signal.

    ℹ️ aei.mpg.de/1138125/mysterious-

    Detected soon after the beginning of the fourth joint observing run of the LIGO-Virgo-KAGRA collaborations, the signal came from the merger of a compact object with 1.3 to 2.1 times the mass of our Sun with another compact object with 2.6 to 4.7 times the solar mass.

    Astronomers believe that the lighter object is a neutron star and the heavier is a lightweight black hole.

    How that lightweight black hole formed is unknown. Its masse falls into the β€œlower mass gap” between the heaviest neutron stars and the lightest black holes.

    This is the problem when two neutron stars get together. Not only does it become a #BlackHole but #Infornation is destroyed.
