The researchers analyzed 22 years’ worth of observations of the galaxy M87.
Observing 22 years of the first black hole humanity has ever imaged has offered “unequivocal evidence” that black holes spin. There’s apparently an oscillating jet that swings up and down roughly every 11 years. An international team of scientists headed by Chinese researcher Dr. Cui Yuzhu analyzed more than two decades of observational data gathered by more than 20 telescopes around the world to make the discovery in the black hole at the center of galaxy M87.
A small fraction of particles not falling into the black hole get jetted out. The telescopes’ observations show that M87’s jet oscillates by 10 degrees in a recurring 11-year cycle —– as Einstein’s General Theory of Relativity predicted. Aside from proving Einstein right, it’s a significant discovery that massively improves our understanding of black holes.Honda has revealed more details about its all-electric Prologue SUV.
