3 days ago · DOI: 10.48550/arxiv.2405.16673. A physicist investigating black holes has found that, in an expanding universe, Einstein's equations require that the rate of the universe's expansion at the event ...
5 days ago · First looks would tell most observers that supermassive black holes (SMBHs) and very young stars have nothing in common. But that’s not true. Astronomers have detected a supermassive black hole ...
5 days ago · In this paper we explain how quantum error correction nonetheless can be used to explain the emergence of the black hole interior, via the idea of “non-isometric codes protected by computational complexity”.
2 days ago · A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. [2] Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
3 days ago · By Evrim Yazgin. One of the major outstanding mysteries of modern physics is the nature of dark matter. According to observations, it should exist. Not only that, to explain gravitational anomalies...
3 days ago · Throughout the series, we'll meld basic physics with the latest research in astronomy, discussing everything from black holes and dark energy to dark matter and the life cycle of a star. We'll get into the human experience of living in space.
3 days ago · Black Holes in Space. Read science articles on colliding supermassive black holes, simulated gravitational waves of a black hole, black hole theory and more. Astronomy images.
