A discovery about black holes
Did you know that there is a discovery about black holes that could change everything you know about them? Read on to find out all about it
Outer space is inhabited by all sorts of strange and beautiful objects – neutron stars, nebulae, galaxy clusters. Black holes are some of the most fascinating. Since German astronomer Karl Schwarzschild first indicated their existence in 1916, researchers have accumulated a wealth of knowledge regarding the elusive giants.
As astronomy evolves more and more advanced, scientists delve deeper into the nature of black holes. Magnetic vortices, radio waves, wormhole theory, record explosions. Over the years, the Stargazers have seen it all and begun to answer some of the questions others posed.
Unprecedented views of the light behind black holes
Black holes are cosmic holes that devour anything, and everything that crosses their path. Their gravity is so great that nothing, not even light, can escape their attraction. So you wouldn’t be able to detect light from behind a black hole. Surely every exhaust must be sucked in, right?
Albert Einstein disagreed. In 1915, a German scientist proposed that extremely massive objects like black holes distort the structure of time and space, allowing light to travel around them. It was a crucial part of his theory of general relativity, an idea that has revolutionized modern physics. Scientists have observed this effect – known as gravitational lensing – but until recently, no one had been able to detect light from behind a black hole.
Then, in July, astronomers at Stanford University smashed it. The team was investigating a supermassive black hole at the center of a distant galaxy called Zwicky when they noticed a strange X-ray emission that they couldn’t put their finger on. They detect signals from the front of black holes, but these new signals are different. These flashes appeared later, and the light was less bright, like the echoes that followed the primary eruption. After much research, the researchers confirmed that these mysterious discoveries were pulses of light that erupted around the edge of the Zwicky black hole, confirming Einstein’s basic theory of relativity.
Astronomers captured the magnetic rotations around the Black Hole’s belt.
In 2019, astronomers assembled history when they released the first image of the outskirts of a black hole. Photographing a black hole is not possible. The pioneering image captured the shadow of M87*, a supermassive black hole 55 million light-years away. Scientists compiled the picture using data from a global network of detectors known as the Event Horizon Telescope.
Two years later, in another unprecedented scientific feat, the team published a new picture that provides more essential insights into the mysterious behavior of the massive celestial body. Finally, in March 2021, researchers discovered another image of M87*, only this time showing magnetic field lines around its shadow.
Black holes like M87* are enveloped by a bright ring of hot cosmic matter. The scientists analyzed the light direction and vibration of this region. Black holes emit massive jets of concern, but no one is sure why. Scientists hope that magnetic vortices can help explain this strange phenomenon.
Observatories detected the record explosion.
In 2016, NASA’s Chandra X-ray Observatory began taking unusual readings from the depths of outer space. A strange curve appears in the Ophiuchus galaxy cluster, about 390 million light-years away. At first, scientists rejected the idea that a black hole created it because the sheer amount of energy involved was too much to be true.
But as more data became available, evidence began to pile up. Eventually, NASA realized that they had detected, in their words, “the largest explosion ever seen in the universe.”
Galaxy clusters are some of the most significant known structures in the universe. They are made up of thousands of galaxies, dark matter, and hot gas. At the center of the Ophiuchus, the cluster is a large galaxy containing a supermassive black hole. Scientists believe that this colossal explosion was caused by that giant space plane. The energy released in the blast is thought to be five times more powerful than the previous record explosion, a massive explosion in the galaxy cluster MS 0735+74.
The study’s lead author, Simona Giacintucci, compared the eruption to the 1980 eruption that tore the summit of Mount St. Helens. “One key difference is that you can stack fifteen Milky Way galaxies in a row into the crater, which punches the cluster’s hot gas.”
Shape-shifting objects lurking near the Milky Way’s Black Hole
Astronomers have recently observed many strange shape-shifting objects in the Milky Way being washed away. Experimenters from the University of California, Los Angeles, discovered them orbiting the Black Hole at the center of our galaxy. The ones furthest from the black hole appear to be the most compact. But as they approach the event horizon, they begin to disappear.
These strange clumps of gas have been dubbed G-objects. Scientists believe they form when two stars are bound together by the enormous gravity of a black hole.
Scientists have observed six mutated G objects in the Milky Way, although it is possible elsewhere in the universe. Nobel laureate Andrea Gage found the first G object in 2005. But it was seven years before investigators in Germany made the second discovery.
Supermassive black holes can be wormholes in disguise
Wormholes are cosmic tunnels through space, taking visitors anywhere in this universe and possibly to other places. A hundred years ago, Albert Einstein explained that wormholes could exist, but no one knows if they do exist.
For years, astronomers have searched the sky for evidence that confirms or disproves the existence of wormholes. But in November 2020, researchers published a paper suggesting they may have stumbled across them without realizing it. Mikhail Petrovich proposed the idea that some black holes could be wormholes.
Black holes and wormholes have more in common than you can imagine. Both are exceptionally special, and both have tremendous gravity. The main difference is that nothing can escape when it enters a black hole, while anything that goes into a wormhole can, in theory, come back. Petrovich and his team hope studying gamma-ray emissions can help confirm their view of gravity.
Black holes merge to create the light of trillions of stars
Black holes lurk in the deep darkness of space, colliding with each other and merging. Until recently, however, scientists thought the process was invisible under darkness.
But now, researchers believe that when black holes collide, and indistinguishable stream of light is produced a trillion times brighter than the Sun. The gravitational wave observatory, LIGO, detected a halo in 2019 that scientists think was caused by the merger of two black holes in the presence of a third black hole. The surrounding gas and dust act as floodlights for the collision, illuminating the catastrophic event.
The lead author, Matthew Graham, explained: “This supermassive black Hole had been running parallel for many years before this sudden outburst. “We conclude that the flare resulted from a black hole merger.”
Scientists photographed radio waves.
The Event Horizon Telescope (EHT) is an incredible feat of engineering. It has eight radio observatories located around the world. Combining their data creates a large, highly accurate telescope the size of Earth.
In July 2021, the EHT project released images of black holes exploding with beams of radio waves. A black hole is in the middle of the Centaurus Galaxy, a galaxy known to emit large amounts of energy, much larger than the Milky Way. But this is the first time scientists have captured a black hole with the same clarity as it does when it throws matter into the sky. The EHT allows scientists to image the jumbo jet with ten times more precision and sixteen times better resolution than previously thought.
Researchers discover a black Hole that captures neutron stars
Black holes and neutron stars are some of the universe’s densest, most exotic objects. When they collide, all hell breaks loose. A collision is a cataclysmic event. The two giant animals merge with such intensity that it creates enormous waves that resonate through space and time.
For many years, scientists have observed two black holes colliding and two neutron stars colliding. But until recently, crashing a black hole into a neutron star was a more formidable challenge.
Then after a long wait, the two came together like buses. In January 2020, astronomers found a signal from merging two black hole-neutron stars within ten days. Scientists believe that both events happened about a billion years ago. Because space is so vast, cosmic echoes reached Earth just last year. In both cases, the black hole is so massive that it consumes the neutron star. 
Astronomers confused black holes with ‘unbelievable’ mass
In 2020, scientists were scratching their heads after discovering a black hole collision that, in theory, should have been impossible. At least one Goliath has 85 times the mass of the Sun, which scientists believe is too massive to participate in that kind of collision.
The distant merger is thought to have occurred when the universe was only half its present age. Theoretical astrophysicist Ilya Mandel described the discovery as an “astonishing surprise.” 
Are black holes an almost infinite source of energy?
British physicist Sir Roger Penrose was an essential figure in astronomy. In 1969, he came up with the idea that future civilizations could use black holes to generate energy. In theory, an object placed close to but not inside a black hole would receive negative energy. Penrose proposed that the thing be split in half, with one half being sucked in by the black hole and the other repelled. The half that has now retreated should have received energy from the black hole. If this energy is harnessed, it could be used to power the entire planet.
When things settle down, this kind of achievement goes far beyond the limits of current technology. But is Penrose right? In 1971, physicist Yakov Zeldovich designed an experiment to test Penrose’s theory of what might be happening here on Earth. Unfortunately, due to technical limitations, Zeldovich’s investigation was also impossible.
Fast forward to June 2020, more than half a century since Penrose first came up with the idea, researchers at the University of Glasgow were finally able to prove their theory. The team created a speaker ring to reproduce the spinning effect of a black hole. They listened as the beams of sound waves were twisted and distorted like the object in Penrose’s original theory.
“We are delighted to be able to experimentally verify some bizarre physics in the 50s after the theory was first proposed.” Professor Daniele Facio told reporters. “It’s strange to think we can confirm a half-century-old theory of cosmological origin in our lab in the west of Scotland, but we think it will open up many new possibilities. a new way of scientific discovery.”
