Black holes can become an endless source of energy for technologically advanced civilizations

Scientists from the University of Glasgow have received confirmation of the reliability of one theory, expressed more than fifty years ago, according to which a very technologically advanced extraterrestrial civilization can use black holes as practically inexhaustible sources of energy. Even the possibility of testing this theory was for a long time beyond the capabilities […]

A star orbiting a supermassive black hole in a spirographic orbit once again confirms the correctness of Albert Einstein

Most of the orbits in which some space objects rotate around other space objects, as a rule, have an elongated elliptical shape. But now, after 30 years of observation, astronomers have determined that one of the stars in the center of our galaxy revolves around the central supermassive black hole Sagittarius A * (Sgr A […]

Astronomers have observed a unique collision of two black holes

More than a year ago, it was possible to fix gravitational waves formed after the collision of two black holes. However, over time it became clear that the collision GW 190412 was really unique. Black holes collided, which significantly differed in their masses. It was a very uneven binary system. The discovery was made on […]

Researchers have found a way to dramatically increase the quality of black hole images

In April last year, the attention of the scientific community was attracted by the first direct shots of a black hole that were taken with the EHT (Event Horizon Telescope). And just the other day, a research team from the Harvard-Smithsonian Center for Astrophysics, CfA, introduced a new method that will dramatically increase the quality […]

The "echo" of gravitational waves confirms Stephen Hawking's hypothesis about the quantum nature of black holes

A kind of echo in the received signals of gravitational waves can serve as confirmation that the event horizon of a black hole is a more complex formation than was previously thought. And recently, researchers at the University of Waterloo were the first to detect the signals of such a gravitational echo, the source of […]

Unusual space objects of a completely new class discovered in the black hole region of our galaxy

Astronomers at the University of California, Los Angeles, working on the Galactic Center Orbits Initiative, have discovered a completely new class of space objects that revolve around a supermassive black hole in the center of our galaxy. Recall that this black hole is called Sagittarius A (Sgr A *), and bizarre objects rotating around it […]

Audi at CES: smart cars and head-up display with 3D

A German manufacturer from Ingolstadt appeared at CES 2020. Audi introduced several solutions that can be implemented in the interior of cars in the future. One of the main attractions is the drone car Audi AI: ME. This is not a model designed for mass production, but only a vision of a city car of […]

Astronomers have discovered a black hole whose parameters absolutely do not fit into existing theories

Black holes are one of the most mysterious space objects, and scientists have only recently begun to understand how they arise and develop, sometimes gaining a stunning mass that exceeds the mass of the Sun by millions and billions of times. However, with some periodicity, scientists find new black holes that do not fit into […]

Thousands of huge strange planets can surround massive black holes

With the exception of a few rare cases, all the planets known to astronomer scientists revolve around stars. And these rare exceptions are the so-called wandering planets, torn from their planetary system by extraneous gravitational forces or the energy of some cosmic cataclysm. However, according to research conducted by scientists from the Japanese National Astronomical […]
