A black hole formula worked out in the 1970s remains the most concrete clue physicists have about the threads of the space-time fabric.
In a recent discovery, astronomers have found that the black hole in the well-known low-mass X-ray binary (LMXB) system V404 Cygni is part of a much larger structure—a wide triple system.
Many black holes detected to date appear to be part of a pair. These binary systems comprise a black hole and a secondary object — such as a star, a much denser neutron star, or another black hole — that spiral around each other, drawn together by the black hole’s gravity to form a tight orbital pair.
Now a surprising discovery is expanding the picture of black holes, the objects they can host, and the way they form.

Astronomers found the exhaust vent of a chimney at our galaxy’s center for the first time.
There is a supermassive black hole at the center of our galaxy that is nearly 17 times bigger than the Sun and can suck in over 1,800 Earths at once. This gigantic black hole goes by the name Sagittarius A* (Sgr A•.
In a new study, a team of researchers claims that Sgr A* has caused the formation of a chimney and an exhaust vent at the center of the Milky Way.

Since its launch, the James Webb Space Telescope has identified early galaxies that shine unexpectedly brightly, suggesting rapid maturity and challenging current cosmological models.
The James Webb Space Telescope (JWST), the largest and most advanced space telescope ever constructed, has been making remarkable discoveries since its launch in December 2021. Among its achievements is the identification of the earliest and most distant galaxies known, which formed just 300 million years after the Big Bang.

This week, researchers reported the world’s second-tiniest toad, winning the silver in the Brachycephalus contest. Chemists at UCLA disproved a 100-year-old organic chemistry rule. And researchers in Kenya report that elephants don’t like bees, which could be a conservation boon (for the elephants. And maybe also the bees?). Additionally, scientists addressed an old thought experiment about monkeys and the theater, physicists correlated dark energy with the black hole population in the universe, and a group of Antarctic seals were found to be highly strategic and also adorable:
Astronomers have possibly found evidence that dark energy — associated with accelerating the expansion of our universe — could also be related with the mysterious black holes.
About 70% of our universe roughly comprises of dark energy and is believed to have born after the Big Bang, around 13.8 billion years ago, though the origin of the force remains unclear, according to LiveScience.
Recently, some astronomers proposed a theory that dark energy could have emerged from the core of gigantic dark abyss called the black holes while others disagreed with the theory.
“We can now see the moment where atomic nuclei and electrons are uniting in the afterglow,” team member Rasmus Damgaard, a researcher at the Cosmic DAWN Center, said in a statement. For the first time, we see the creation of atoms, we can measure the temperature of the matter, and we can see the microphysics in this remote explosion.”
“It is like admiring three cosmic background radiation surrounding us from all sides, but here, we get to see everything from the outside. We see before, during, and after the moment of birth of the atoms.”
Neutron stars are born when stars at least 8 times as massive as the sun exhaust their fuel for nuclear fusion and can no longer support themselves against their own gravity.
Scientists in Virginia are looking for mysterious dark matter — and have turned to really old rocks.
The substance, which makes up more than 80 percent of all matter in the universe, shapes and affects the cosmos. But it is entirely invisible and remains undetectable by normal sensors and techniques.
Analyzing billion-year-old rocks, researchers at Virginia Tech hope to find traces of dark matter. The idea was first proposed in the 1980s. Technological advances since then led them to revisit the idea. What if there were traces in Earth’s minerals?
A radical hypothesis suggesting black holes could be behind the accelerating expansion of our universe has been stirring up controversy among astronomers. A new study may contain the first tantalizing hints it could be real.
https://lnkd.in/gPGP3Q3j In this article, we propose a new Feynman’s path integral approach and extend this formalism into curved spacetime and consider its possible implications for black hole physics. While still a work in progress, this model suggests that black holes, rather than representing the final stages of gravitational collapse, might contribute to the formation of new universes. We carefully examine both Schwarzschild and Kerr metric of rotating and non-rotating black holes. We derived that rotating black hole will create a traversable worm hole without exotic particles and non-rotating back hole will create another universe by interpretation of path integral finally. We proposed the way how to create the wormhole between two interstellar space using qubits. This proved ER=EPR. John Preskill Dear Professor Preskill Please help me check it Sir.
