These scientists have put out an ambitious new theory, and subsequent work will either back them up or respectfully disagree, citing different analysis and observation. So, what do these findings mean? Well, when it comes to the swirling mysteries at the heart of the galaxy, all news is good news. They’ve expanded their study to the closest, most well-understood stars orbiting Sagittarius A* and found those stars also behave consistently with a dark matter model. In this new study, accepted for publication by MNRAS Letters, the Italian, Argentinian, and Colombian scientists explain that not just the directly affected G2 and S2 space objects line up with the dark matter theory. And if it is a kind of proto future black hole, that could explain how supermassive black holes form in the first place-something scientists have been puzzled by for decades. For now, it could just be a dense blob that still attracts nearby objects as a black hole does.

The World Wide Web, or simply Web, is a way of accessing information over the medium. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet. But its presence, along with the related idea of dark energy, makes up a total of 99.5 percent of the mass of the universe around us and provides the missing piece to a ton of questions in physics and cosmology.ĭark matter can and does turn into black holes, but the scientists posit that Sagittarius A* is instead a blob-like mass that will require a lot more material in order to turn into a black hole. The Internet is a massive network of networks, a networking infrastructure. Dark matter makes up 30 percent of the mass of our universe, yet it’s invisible and, so far, not directly observed. Even if you couldn’t see the drain directly, the behaviors around it would give you clues.ĭark matter is matter that we can’t see, but we can measure it through its effect on gravity and objects around it. Think about how soap suds behave as water swirls down your drain and what that tells you about what the drain is doing. S0-2 and other established stars are pulled every which way in their orbits around Sagittarius A*, into extreme orbits that scientists measure in order to get some idea of what the supermassive black hole is all about. That supermassive black hole is called Sagittarius A*. Scientists study these objects in orbit as a way to extrapolate what they’re actually orbiting around-in this case, “a supermassive black hole 4 million times the mass of the Sun,” ScienceAlert explains. The idea of a supermassive black hole at the center of the Milky Way is well-established, based partly on the orbit of specific stars like S0-2. What if the center of our galaxy isn’t a supermassive black hole after all, but instead, a massive amount of dark matter? That would flip our long-held understanding of the Milky Way, but in a new study, scientists from Italy, Argentina, and Colombia say the evidence stacks up.

If it’s true, this could help explain how supermassive black holes originate.

The study is based on observations of the objects that orbit closest to the center.

The center of the Milky Way could be dark matter instead of a supermassive black hole, according to a new study.
