Science TimeString theorist, mathematician and theoretical physicist Brian Greene talks about black holes, quantum gravity and the possibility of our Universe being a hologram. Brian Greene thinks string theory has potential to reconcile quantum gravity and general relativity.
He also brings attention to the question “Could the whole universe in fact be a hologram? This is not just a wild speculation but a theory that scientists take very seriously, even if they can not completely understand it.
The idea is that “everything is just a 2-dimensional projection” of the rest of the universe, and from this perspective, our three-dimensional world is actually a hologram.
According to Brian Greene, this is a hard idea even for physicists to fully grasp and they are still trying to really understand in detail what this would mean.
The holographic principle, came out of the study of the most extraordinary objects that are known to exist in the universe – black holes. They could hold the key to unlocking the next phase in our understanding of the laws of physics.
There’s a similarity of black holes and the big bang, in that both are space-time singularities where the laws of physics break down.
We think of the big bang as a moment when the entire observable universe was crushed to a very small size. So, according to Brian Greene, they’re kind of the same in some deep mathematical sense.
Stephen Hawking believed information that enters a black hole is lost forever. Many scientists believe that the information we see all around us is actually encoded on a big surface that surrounds us, a thin two-dimensional surface that sort of is like a hologram.
The holographic principle was given a precise string-theory interpretation by Leonard Susskind, a physicist at Stanford University.
According to this holographic Universe theory, our “reality” is also encoded in the structure of space itself. Like a normal hologram, such a universe would be fundamentally two dimensional.

A grand challenge in modern theoretical physics is to find a ‘unified theory’ that can describe all the laws of nature within a single framework – connecting Einstein’s general theory of relativity, which describes the universe on a large scale, and quantum mechanics, which describes our world at the atomic level.

03/07/2025 - 2:20 PMThe holographic universe is widely revered as one of the most important breakthroughs of the past few decades.
The reason is that it strikes at the mystery of quantum gravity – the long-sought unification of quantum physics, which governs particles and their interactions, and general relativity, which casts gravity as the product of warped space-time.
Then again, you might wonder why the idea is held in such high regard given that it remains a mathematical conjecture, which means it is unproven, and that the model universe it applies to has a bizarre geometry that doesn’t resemble our universe.
The answer, it turns out, is twofold.
First, the holographic conjecture has helped to make sense of otherwise intractable problems in particle physics and black holes.
Second, and more intriguing perhaps, physicists have finally begun to make headway in their attempts to demonstrate that the holographic principle applies to the cosmos we actually reside in.

03/07/2025 - 2:20 PMhehe…let anyone who thinks that the universe is a hologram come and let me slap him and think again!! living in a time when evry fools have the right to present any theory only externally connected as an authentic possibility!! it's a shame how many of those who, in today's hype of the sci prefix, rely on the egoistic assumptions of various phds who long for their stupidity to be sold!! they can always write sf novels but not they would do it a little easier and faster !! and black holes, theories and curiosities will make me chronically vomit, hehe!! horror !!

03/07/2025 - 2:20 PMYes it is Holographic. I have found gravity and I can prove it in five seconds.
Cut and paste the following into GPT and you will see.
1. Consider a black hole 1KM radius. Calculate the gravity energy in Joules per Planck Area.
2. Obtain the Hawking Temp of that black hole.
3. Plug Hawking T into Landauer.
4. Report GR results in Joules. Report Landauer in Joules and divide GR by Landauer and report that factor.
This is it! Maxwell’s demons pays one unit of gravity and one of Hawking radiation every time the demon measures an entangled pair. Here is Bell’s addition to account for the energy for the non-local correlation.
E emission = E Not A + E Not B = E gravity + E photon
E ‘(θA ,θ B ) = −cos(θ A −θ B ) + f(not A,not B),
where f(not A, not B) accounts for the energy cost associated with maintaining non-local correlations on the Holographic surface. This is the payment for Bell’s services.

03/07/2025 - 2:20 PMAccording to the hollow-graphic principle, when we cast a shadow on a 2D surface.. Thats the hollow-graphic principle.
Some would say that’s what UAP’s could be.
A 4D object projecting its shadow onto our 3D plane.

@isatousarr7044
03/07/2025 - 2:20 PMThe idea that the universe might be a hologram arises from intriguing theories in quantum gravity and black hole physics, suggesting that our three-dimensional reality could be a projection of information encoded on a two-dimensional surface. This concept, linked to the holographic principle, proposes that the fundamental descriptions of space, time, and gravity might be fundamentally different from our perceptions. If black holes are indeed manifestations of this holographic principle, what does this mean for our understanding of quantum gravity, and how might it transform our view of the universe's fundamental nature?
@ZhanMorli
03/07/2025 - 2:20 PM❤for 119 years❤❤ By determining the constancy of speed of light, all experiments and Michelson-Morley experiments are indirect and incomplete. If the Michelson-Morley experiment was carried out on a bus or airplane and was used to determine speed. only then will this experience be direct. Therefore, Einstein does not rely on the Michelson-Morley experiment. Question. Do you have an example of such direct experience?
New technologies, new research tools
Let me suggest for schoolchildren and students on one's own to measure the Universe, dark energy, black holes, etc. To do this, I propose two practical devices. «laser tape measure +reference distance 1,000,000 m”» and «Michelson-Morley HYBRID Gyroscope». I am writing to you with a proposal for the joint invention of a HYBRID gyroscope from non-circular, TWO coils with a new type of optical fiber with a “hollow core photonic-substituted vacuum zone or (NANF)” where – the light travels 250000 (In a laser tape measure, the length of the optical fiber is fixed at 1000000 ) meters in each arm, while it does not exceed the parameters 84/84/84 cm, and the weight is 24 kg. Manufacturers of “Fiber Optic Gyroscopes” can produce HYBRID gyroscopes for educational and practical use in schools and higher education institutions.
Einstein dreamed of measuring the speed of a train, an airplane – through the Michelson-Morley experiment of 1881/2024, and only then would the experiment be more than 70% complete. This can be done using a fiber optic HYBRID gyroscope. Based on the completion of more than 70% of Michelson's experiment, the following postulates can be proven:
Light is an ordered vibration of gravitational quanta, and dominant gravitational fields adjust the speed of light in a vacuum. you can make scientific discoveries; in astronomy, astrophysics, cosmology, higher theoretical physics,… (We are not looking for ether, we will see the work of gravitational quanta) The result is a «theory of everything» in a simple teaching device and a new tape measure for measuring the universe.

@chrisgascoigne6199
03/07/2025 - 2:20 PMA hologram requires line of sight to project a 3D image. A single object would be represented everywhere on the 2D circumference of the sphere; but what if you put this object in a box? Does this not now block the projection from certain angles and effectively put the first object out of sight and unable to receive information? How can you have layers of information on a 2D surface? Very confusing and seemingly pointless to me.
