A new theory is challenging everything we know about Sagittarius A*, the supermassive object at the heart of our galaxy. For decades, physicists have been certain it’s a black hole. They have observed its effects and even built a planet-sized telescope just to image it. But now, a mind-bending theory is turning our understanding upside down. What if Sagittarius A* isn’t a black hole at all, but something far stranger?▀▀▀▀▀▀Start speaking a new language in 3 weeks with Babbel 🎉.
