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.
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, black holes 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 gravity. According to the relativity, black holes are simple bodies without information. According to quantum physics, 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.
We’re getting closer to technologies that let us exist forever in some way — using data to power our existence in VR, robots, chatbots and holograms. Should we do it?

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.

The tactile sensation is said to be very realistic-feeling.
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.

Internet businessman Dmitry Itskov, 38, is bankrolling a far-fetched plan to uploaded people’s personalities to artificial brains.
These “brains” can then be jammed into robots or holograms, allowing us to live on forever as artificial versions of ourselves, Dmitry claims.
Water is special even based on its simple physical properties since it is the only substance on earth that can be found in all three states (liquid, solid, gas). However, scientists at the US Department of Energy Oak Ridge National Laboratory (ORNL) have discovered new properties of water that go beyond the known laws of classical physics says the phys.org scientific news portal.
