Why do some scientists It is believed that we live in a black hole. Is this a possibility? If in theory Such a black hole would be larger than our entire universe.
Black holes (Black Holes) are the strangest objects in the universe. It is so extreme that even current science cannot fully explain it.
Even though humanity has known about it for hundreds of years. Yet it still confuses today’s physics. In many attempts to understand it Some scientists have proposed a different idea.
Many people said “We all live in black holes,” in other words. Everything from matter to large stars, galaxies, and the entire visible universe now reside in black holes.
While others claim that our universe is a hologram. which says that all that we see and perceive is real. It is encoded within our own universe. The feeling that our universe is 3D is created by the 2D display plus time.
But the important thing is A black hole is an object that sucks everything in. Some scientists therefore believe that all matter that enters it is decomposed into the simplest form of information. That has led many experts to believe that there may be a possibility. That information will be reconstructed into ‘something’ inside.
“In the general theory of classical relativity Black holes prevent any particle or form of radiation from escaping its cosmic prison,” said French astrophysicist Jean-Pierre Luminet.
“For outside observers When an object crosses the event horizon All knowledge about the properties of that material is lost. Only the new values of mass (M), angular momentum (J), and electric charge (Q) remain. The result is that black holes consume enormous amounts of data.”
That means the hole is behaving like A ‘data storehouse’ of everything it devours. Therefore, if we go in and pry out the said information, We’ll be able to ‘recreate’ what the data used to be. As amazing as it sounds, black holes themselves in some ways follow simple physics: they follow the First Law of Thermodynamics, according to Stephen H. Awking proved it. which is called ‘Hawking radiation’ forms at the boundary of a black hole
“Hawking points to a contradiction. If black holes could evaporate Some of the information therein will be lost forever,” Luminate continued. “The information contained in the thermal radiation emitted by the black hole will be degraded. with no conclusive information about the matter previously swallowed by the black hole.”
But it also has problems as well. Because current quantum theory says that nothing disappears. According to Schrödinger’s equation, Physical systems that change over time Data cannot be created or destroyed. All this conflict has kept scientists on their toes for decades. And there was a lot of debate.
Black holes are our home.
But it turns out that the best way to solve the problem is ‘We are in a black hole’ as mentioned above. Some people believe that it is what makes everything fall into place. Gerard Hooft (Gerard ‘t Hooft) used string theory to help. He points out that all degrees of freedom can exist within a black hole. It uses the surface area of the horizon to determine its boundaries. instead of the volume of the black hole
“From a data perspective Each bit in the form of 0 or 1 corresponds to a four-point Planck space. This makes it possible to find the Begenstein-Hawking formula for entropy,” said Luminet. “For outside observers Information about black hole entropy, which once emerged from the three-dimensional structure of objects crossing the event horizon, appears to have disappeared.
But from this point of view The information is encoded in two dimensions. The surface of a black hole is like a hologram, so Hooft concluded. The information swallowed by the black hole can be completely recovered during the process of quantum evaporation.”
This may sound confusing to the general public. But we can easily conclude that the absorbed matter is broken down into 0 or 1 bits of information which are then encoded in 2D which are stored in a hologram-like state. Which if we are in a black hole as big as the universe We can recover all the information that the black holes in the universe swallowed. Because both we and the black hole are in a black hole again. and information evaporated from Hawking radiation Still in the black hole we live in
That can lead to the conclusion that ‘The world formed in a black hole’ or to put it another way. The universe formed in black holes.
“Black holes are very similar to the Big Bang. On the other hand, the mathematics looks similar,” said Gaurav Khanna, a black hole physicist at the University of Rhode Island. As the black hole collapsed, Very small, very dense spots. “Until it exploded and a baby universe formed inside the black hole,” he added.
This idea was supported by an October 2023 study in which Dr. Charles Lineweaver and graduate researcher Vihan Patel created a chart that An interesting issue arose. They both called it ‘Chart of everything’
By using the temperature, density, mass, and radius of the object. They have collected everything from atoms, people, planets, galaxies and, most importantly, the universe. When the chart is visible We can see that the smallest quanta are at the bottom of the graph. But as we went up, the pair observed that the universe is within large bounds of the temperature, density, mass, and radius of objects being as high as possible.
This also corresponds to the largest possible black hole. That puts the entire region of our observable universe in black holes.
“The universe could be an inside-out black hole,” Dr Lineweaver said, while Scott Field, an associate professor of mathematics at the University of Massachusetts Dartmouth, added, “If We are in a black hole It must be very large.
And if so Scientists hope to see subtle distortions caused by strong gravity, such as the slowing of time and the contraction of matter. As people move inside the black hole
We don’t know anything.
However, no one is currently able to detect anomalous occurrences, such as if the Earth were contained in an Earth-sized black hole. People notice the effects of tidal forces, matter is stretched, and time slows as they travel from one point to another.
But we all live normal lives. Therefore, if we were really in a black hole, it would have to be as large as the universe. Until they couldn’t travel fast enough to see the difference. or see the distortion of gravity Our current knowledge is not enough to answer many questions.
But that doesn’t mean scientists won’t stop searching. With one of the biggest questions of the moment, we can now enjoy imagining the universe we live in without worrying.
