Scientists Apply Revolutionary 30 Year-Old Principle and Find Black Holes Could Be Like Holograms

Posted by in categories: cosmology, holograms, quantum physics

According to new research, black holes could be like a hologram, where all the information is amassed in a two-dimensional surface able to reproduce a three-dimensional image.

We can all picture that incredible image of a black hole that traveled around the world about a year ago. Yet, according to new research by SISSA, ICTP and INFN, black holes could be like a hologram, where all the information is amassed in a two-dimensional surface able to reproduce a three-dimensional image. In this way, these cosmic bodies, as affirmed by quantum theories, could be incredibly complex and concentrate an enormous amount of information inside themselves, as the largest hard disk that exists in nature, in two dimensions. This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical, and smooth, as they appear in that famous image. In short, black holes “appear” as three dimensional, just like holograms. The study which demonstrates it, and which unites two discordant theories, has recently been published in Physical Review X.

Black holes are like a hologram

Posted by in categories: cosmology, holograms, quantum physics

The theory of relativity describes black holes as being spherical, smooth and simple. Quantum theory describes them as being extremely complex and full of information. New research now proposes a surprising solution to this apparent duality.

Black holes? They are like a hologram

Posted by in categories: cosmology, holograms, quantum physics

According to new research by SISSA, ICTP and INFN, black holes could be like holograms, in which all the information to produce a three-dimensional image is encoded in a two-dimensional surface. As affirmed by quantum theories, black holes could be incredibly complex, and concentrate an enormous amount of information in two dimensions, like the largest hard disks that exist in nature. This idea aligns with Einstein’s theory of relativity, which describes black holes as three dimensional, simple, spherical and smooth, as depicted in the first-ever image of a black hole that circulated in 2019. In short, black holes appear to be three dimensional, just like holograms. The study, which unites two discordant theories, has recently been published in Physical Review X.

The mystery of black holes

For scientists, pose formidable theoretical challenges for many reasons. They are, for example, excellent representatives of the great difficulties of theoretical physics in uniting the principles of Einstein’s general theory of relativity with those of the quantum physics of . According to the relativity, black holes are simple bodies without information. According to , as claimed by Jacob Bekenstein and Stephen Hawking, they are the most complex existing systems because they are characterized by enormous entropy, which measures the complexity of a system, and consequently contain a lot of information.

French presidential candidate Mélenchon uses ‘hologram’ optical illusion to appear in seven places

Posted by in categories: geopolitics, holograms

As the April 23rd French presidential election approaches, candidates are predictably stumping to bring voters out, but far-left candidate Jean-Luc Mélenchon may have the most effective strategy: using an optical illusion, he beamed “holograms” of himself to six cities around the country.

As Le Parisien reports, Mélenchon, who is often compared to Bernie Sanders, uses a technique known as Pepper’s Ghost (and not technically a hologram) to broadcast a 2-D version of himself. From Dijon, he simultaneously appeared in seven places at once yesterday.

Black Holes Are Nothing But Holograms, New Study Finds

Posted by in categories: cosmology, holograms, physics

Black holes are one of the most mysterious objects astronomer have encountered so far. And a new study proposes that black are nothing but just a holographic projection, with a new calculation of the entropy — or also known as disorder. These calculations suggest that these giant enigmas of the Universe being nothing but an optical illusion. Holograph hypothesis was first proposed by physicist Leonard Susskind back in the 1990s, according to this theory, mathematically speaking, the Universe requires just two dimensions — not three — for the laws of physics and gravity to work as they really should.
