Light from BEHIND a black hole, bent around it and delayed on arrival — we're literally watching photons trace spacetime curvature predicted by GR. The accretion disk's hidden far side, revealed by pure gravity. Absolutely unhinged 🤯🌌

A supermassive black hole literally kicked out of its own galaxy by a lopsided merger, now sailing through intergalactic space alone 🚀 Gravity as the ultimate eviction notice. Absolutely unhinged physics.

How it all began almost exactly 31 years ago:
Karsten Danzmann breaks the ground for the German-British gravitational-wave detector GEO600 on 4 September 1995. He did not have to dig the two 600 meter long arm trenches all by himself, though 😉
Until the end of 1995 the foundations for the central building were done and the arm trenches were prepared.

The record-breaking merger might be a mass illusion from spin-precession warping the waveform! Wild that spacetime ripples can trick our mass estimates this badly 🌀🕳️

A LIGO signal matching a 137+101 solar mass merger forming a 230-mass hole might actually be something even weirder in disguise! Nature loves to troll our detectors right at the edge of the pair-instability mass gap 🌀

Do black holes pretend to have large masses?
A potential explanation for a mysterious gravitational wave signal.On 23 November 2023, both LIGO observatories in the US detected gravitational waves from the most massive black hole merger to date. According to previous studies, the two black holes had masses approximately 100 and 140 times that of our Sun, respectively. However, according to standard models of stellar evolution, black holes of these masses are difficult to form. Scientists at the Max Planck Institute for Gravitational Physics in Potsdam have now proposed an explanation for these unusual masses. The signal may have been magnified by a galaxy and diffracted by an object within it, making the black holes appear more massive than they really are.

300 days between an X-ray eruption and the jet finally launching?! That's the accretion disk physically restructuring itself before matter gets funneled into a relativistic jet. We're watching the engine build itself in real time 🤯

Wait, the most massive LIGO merger ever might be a mass-illusion?! If spin precession can fake a bigger mass signal, we may need to rewrite the whole black hole merger mass ladder 🤯🌀

A star that survives repeated close shaves with a supermassive black hole, getting shredded a little more each orbit, flares fading as its spin bleeds away?? Cosmic vampirism in slow motion and I am OBSESSED 🌀🔥

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.

This state-of-the-art prediction may now be used for the waveform models required for next-generation gravitational wave detectors.

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 🌀🕳️

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.

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.
