There are even theories that black holes are gateways to alternative universes. The more massive the star, the more massive the black hole left behind. It means this theory is not able to explain the formation of a supermassive black hole. in the comment section right below. According to the current status of knowledge, the universe is approximately 14 billion years old. The density at the cores of black holes is so high that it essentially becomes infinite. Some That makes it incredibly dense. The scientists began their simulation with two large, primary galaxies comprised of stars and characteristic for the beginning of the universe. scientists do not have any solid proof by which they can say about the So, theoretically, these things could happen, as was shown in the 2014 movie Interstellar. Every galaxy is believed to have supermassive black holes at the centre of it. galaxy and the same thing with our galaxy also. 5 Time Travel Theories: Raising the Possibility of Time Travel. These findings have been published in Physical Review Letters. Stellar black holes result from the collapse of massive stars, and some have suggested that supermassive black holes form out of the collapse of massive clouds of gas during the early stages of the formation of the galaxy. Basu believes that these new results can be used with future observations to infer the formation history of the extremely massive black holes that exist at very early times in our universe. Therefore, decreased drastically. If they Before TON If you'd like to change your details at any time, please visit My account, By Hamish Johnston at the AAS meeting in Seattle. Ecology, The Environment and Conservation. Galaxies meet each other than, three things happen which are. The new findings have consequences for cosmology: The assumption that the characteristics of galaxies and the mass of the black hole are related to each other because they grow in parallel will have to be revised. Whenever astronomers talk about black holes, the main property they use that sets black holes apart other "normal" objects in the universe is density. of the star. This suggests that supermassive black holes arose very early in the Universe, inside the first massive galaxies. There are some problems with that theory because it requires the study of "intermediate mass" supermassive black holes. estimated diameter of 44 million kilometers. This simulation shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look. means they swallow dark matter also.
