Sagittarius A* Might Not Be a Black Hole
6/18/202626 min
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?▀▀▀▀▀▀

This is Sagittarius A*. For decades, astronomers have tracked the orbits of its closest stars, and every observation has pointed towards the same conclusion. It is almost certainly a super massive black hole. But even with the publication of the iconic image that came from the Event Horizon Telescope in 2022, it's important to remember that this hasn't yet been proven. And now, fresh research is rewriting this familiar story.
