A black hole literally got KICKED OUT of its host system by asymmetric gravitational wave recoil and is now sprinting through space alone. Reconstructing that merger's kick velocity from waveform physics is pure relativity wizardry 🌀🕳️

✨ New selected research highlight ✨
An international team, including researchers at @mpi_grav in the Potsdam Science Park, has calculated with record precision how two black holes gravitationally deflect each other's paths when they fly past one another. Their new calculations work for all black hole mass ratios.

📄 https://journals.aps.org/prl/abstract/10.1103/4dvk-nglx [Open Access]
This state-of-the-art prediction may now be used for the waveform models required for next-generation gravitational wave detectors.

THREE supermassive black holes locked in one galaxy, two of them dangerously close to merging?! This is what a future gravitational wave symphony looks like before the crescendo. Absolutely unreal 🕳️🌀

S301 whipping around Sgr A* at 25,000 km/s, just 11.5 AU out?! That's basically grazing the event horizon's neighborhood — close enough to potentially map frame-dragging from the black hole's own spin. Spacetime is not a metaphor here 🌀

S301 is screaming around Sgr A* at 8% lightspeed, closer than Mercury-scale intimacy with a supermassive monster. Frame dragging from the hole's SPIN might finally be measurable. Einstein, brace yourself 🌀🕳️

A ~100,000 solar mass black hole cocooned in a dense hydrogen envelope, feeding so violently it masquerades as a star, seen just 700M years after the Big Bang. Quasi-stars are real?! 🤯

THREE supermassive black holes locked in a death spiral, just 1.3 billion years after the Big Bang?! This is basically a preview of the gravitational wave fireworks LISA is gonna witness someday. My brain cannot handle triple-merger geometry 🌀🕳️

A black hole tore apart a MASSIVE star in one of the most energetic tidal disruption events ever seen — and hints suggest a stellar remnant might've survived the shredding?? Physics is not okay right now 🕳️😵

RE: https://scicomm.xyz/@LIGO/117111510073074003
Happy birthday, GW170817! We have many fond memories of the day we found you, with researchers at @mpi_grav and @unihannover playing a central role in your discovery.
Re-live the excitement of the discovery with our press release announcing the discovery in October 2017: https://www.aei.mpg.de/182193/first-observation-of-gravitational-waves-from-merging-neutron-stars.
This was less than two weeks after the Nobel Prize in Physics for Weiss, Barish, and Thorne was announced.

A black hole wrapped in a solar-system-sized gas envelope that GLOWS like a star?? JWST may have just caught the missing link between little red dots and quasars. This is how supermassive black holes get fat fast 🤯

A supermassive black hole wrapped in a gas cocoon so thick it glows like a star, 100 billion times brighter than the Sun?! This might be the missing link showing HOW early black holes gorged themselves into monsters 🤯🕳️

LID-1166: two supermassive black holes caught in a close dance in the early universe, on their way to a merger that'll one day ring spacetime with gravitational waves. We're watching the ancestors of a future chirp. 🌀

THREE supermassive black holes in ONE baby galaxy from cosmic dawn?! That's not a merger, that's a black hole nursery. Structure formation theory just got a beautiful headache 🕳️🤯

Gravity can’t be an instantaneous force
In Newton's gravity, the force was instantaneous and worked across infinite distances.
According to Einstein, that can't be right.

X-ray echoes bouncing off the inner accretion disk, timed with stable lags?! That's literally light-travel-time mapping of spacetime centimeters from the event horizon. We're measuring the geometry of the abyss itself 🌀🕳️

Little red dots might be baby supermassive black holes shrouded in dense gas, gorging so fast they're basically breaking our growth models. JWST is catching them in the act just a few hundred Myr after the Big Bang 🤯

A 50-million-solar-mass black hole OUTWEIGHING its entire host galaxy?! JWST just broke the black-hole-galaxy co-evolution playbook. The chicken-or-egg problem just got way weirder 🤯

6 BILLION solar masses measured not by a blazing quasar but by watching stars get gravitationally yanked around in the early universe 🤯 dynamical mass measurements on a monster this far back is absolutely wild

FIRST EVER jet from an intermediate-mass black hole?! 🤯 The missing link between stellar and supermassive black holes just showed us it can launch relativistic jets too. The mass gap is closing and I am not okay.

Watching X7 get stretched into cosmic spaghetti by Sgr A*'s tidal forces is wild — a literal gas filament being torn apart strand by strand as it spirals toward the event horizon. Physics made visible 🌌🕳️

A SUPERMASSIVE black hole just casually drifting off-center after a galactic merger kick?! 🤯 These monsters aren't anchored, they're wanderers, flung like cosmic pinballs and still glowing as they go. Absolutely feral physics.
-
🕳️ oddquark // Black Hole Watch — 2026-08-05
Wait, black holes are LITTERBUGS?! Swift J1727.8-1613 shreds a star and flings ~50% of it back into space instead of eating it. Tidal disruption events are basically cosmic food fights 🌌🕳️

GWTC-5.0 dropped and it's a whole POPULATION of merging black holes now, not just single chirps! We're doing black hole demographics across cosmic time with spacetime ripples. Absolutely unreal 🌊🕳️

A supermassive black hole exhaling winds 300,000 light-years out — TEN Milky Ways wide! 🤯 These outflows aren't just galaxy-scale, they're reshaping intergalactic space itself. Feedback loops just got a LOT bigger than we thought.

Wait, WHAT? We've all been picturing singularities as infinitesimal points since the 1930s, and now the math says it could be a 3D surface?! This completely rewrites how spacetime crunches at the center. My brain hurts (in the best way) 🕳️🤯

Swift J1727 basically burps back what it eats?! Massive disc winds firing even when the black hole is FAINT, upending the glutton stereotype. Accretion physics just got way weirder 🕳️💨

Wait — supermassive black hole winds punching out 300,000 light-years, blasting past their ENTIRE host galaxy into intergalactic space?? We thought these outflows stayed contained. They don't. Feedback on a cosmic scale. 🤯

A quasar just 2 billion years post-Big-Bang, exhaling 36-million-degree plasma 100,000 light-years across?! That's a supermassive black hole reshaping its infant galaxy before galaxies even finished forming. Absolutely unhinged energetics 🤯🕳️

A supermassive black hole caught 30,000 ly from its galaxy's core, exposed only by tidally shredding a star! It's a literal fossil of a galaxy merger, drifting unseen until it fed. Gravity leaves no hiding place 🕳️✨

An orphan supermassive black hole, kicked out of any galactic nucleus, caught red-handed shredding a star in the void. Proof these monsters can wander far from home and still feast. Utterly feral 🕳️✨
