Einstein\u2019s general theory of relativity comes with a lot of consequences that can best be described as \u201cweird.\u201d Now, for the first time, astronomers have directly observed one of those weird consequences\u2014a whirlpool in the very fabric of spacetime caused by a rapidly spinning black hole.<\/p>\n Every so often, an unlucky star wanders into the maw of a black hole where, just like everything else, it gets \u201cspaghettified<\/a>\u201d\u2014stretched and shredded by immense gravitational forces. Known as a \u201ctidal disruption event\u201d (TDE), this star-eating phenomenon is a messy affair, with leftover stellar material forming a disk and jets of matter erupting into space at a blistering pace.<\/p>\n By measuring the radio waves and X-rays emanating from the disk and the jets of just such a tidal disruption event (called AT2020afhd), astronomers discovered they were wobbling, and wobbling in unison. Essentially, the massive black hole at the center of the TDE was spinning in such a way that it dragged spacetime with it, creating a vortex. They published their findings<\/a> recently in Science Advances.<\/p>\n ADVERTISEMENT<\/p>\n Nautilus Members enjoy an ad-free experience.
