Without more data, a black hole’s origins can be “rotated” in any direction

An MIT study reveals that, for now, the catalog of known black hole binaries does not reveal anything fundamental about how black holes form. Pictured is a simulation of light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Credit: NASA Goddard Space Flight Center Clues to a …

Simulations predict existence of radio wave hotspots in black holes

Simulations predict existence of radio wave hotspots in black holes

Some of the synthetic images produced by the researchers show the hotspots spinning as an observer spins around the black hole’s spin axis. Credit: Crinquand et al Black holes, regions of spacetime where gravity is so strong that nothing can escape, are among the most fascinating and studied cosmic phenomena. Although there are now countless …

Study rules out primordial black holes originally clustered as dark matter candidates

Pixabay. Primordial black holes (PBH) are fascinating cosmic bodies that have been widely studied by astrophysicists around the world. As their name suggests, these are black holes that would have appeared in the early days of the universe, less than a second after the Big Bang. Physics theory suggests that in the split second before …

New space observatory helps solve mystery involving huge black holes

New space observatory helps solve mystery involving huge black holes

Most galaxies are built around huge black holes. While many of them are relatively docile, like the one at the center of our Milky Way, some are ferocious – gobbling up surrounding material and releasing huge jets of extremely bright high-energy particles far into space. Using data from the recently deployed Imaging X-ray Polarimetry Explorer …

We Finally Know How Black Holes Produce the Brightest Light in the Universe

For something that emits no light that we can detect, black holes love to blanket themselves in radiation. In fact, some of the brightest light in the Universe comes from supermassive black holes. Well, not really black holes themselves; it is the material that surrounds them as they actively suck up large amounts of matter …

Wormholes may look almost identical to black holes, researchers suggest

Polarization in a vertical magnetic field for wormholes with different redshift parameters α. Each color represents the observable polarization of the orbits located at r=6M (outer ring) and r=4.5M (inner ring) for a particular wormhole solution with α∈[0,3]. The Schwarzschild black hole polarization is given by a black dotted line as a reference. The angle …
