ESA's XMM-Newton spacecraft has detected an unprecedented X-ray signal coming from the very edge of a supermassive black hole.

This defies how we thought matter falls into black holes, and points to a potential source of gravitational waves for ESA’s future LISA mission.

TLDR ; Physicists cannot exactly explain x-ray 10% amplitude oscillations at periods from 400s to 1000 s, observed from the surrounding of a black hole, despite some hypothesis including that a white dwarf would be orbiting it at aprox 50% light speed.

despite some hypothesis including that a white dwarf would be orbiting it at aprox 50% light speed.

Damn, can you imagine the time dilation for that region? It's a white dwarf which has a fair amount of its own gravity, then it's traveling at half the speed of light, and it's on the edge of a supermassive black hole. I'll bet time just stands still there, while the universe zooms around it.

@A_A@lemmy.world Thank for for the TLDR
