World Science Festival
World Science FestivalWhen Stephen Hawking elegantly described the relationship of quantum mechanics with black holes, he inadvertently opened the door to a radical possibility: that our universe, as we know it, is like a hologram. Science historian Peter Galison and leading physicists Brian Greene and Cumrun Vafa explain how the resilient nature of information combined with the behavior of event horizons suggests that the three dimensions of reality we observe may in fact be a two-dimensional information structure “painted” on some sort of cosmological horizon.

02/20/2025 - 11:05 AMThe 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.

02/20/2025 - 11:05 AMwhat do you mean by information disappears?as i now information gets to its receivers
@catie33336
02/20/2025 - 11:05 AMTo me this is "evidence", in a way, of the philosophical/spiritual concept of nonduality. As the Heart Sutra says "form is empty. emptiness is form" and this is comparable to the idea that our 3D reality exists as a projection of information encoded onto a distant 2D surface. You are the universe perceiving itself – the observer and the observed cannot be separated, they are one and the same. that is why you must do whatever makes you happy in life, be you, who is a projection of encoded information far away. you control that information through your thoughts, speech and actions in this world!

02/20/2025 - 11:05 AMSo when the hologram crosses the threshold of the surface of the projector, it freezes. What happened to spaghettification and all that?

02/20/2025 - 11:05 AMHow can a black hole attract things that are only illusions? Is the black hole also a hologram?
@LiminalArcade1
02/20/2025 - 11:05 AMI asked chatgpt if my theory of black holes was correct. Then i was referred to this principle. I first thought of this idea when playing around with an accretion disk simulation.
The black hole is probably bothing but an optical illusion caused by the bending of spacetime.

@chetnadethe8172
02/20/2025 - 11:05 AMSo does that mean we are a computer program in codes but in 3d we are in holographic state which means there is a system that stores this information and blackholes are a recycle bin.. they evaporate so after evaporating the holographic system never comes back as whole or does it?
@rustysim
02/20/2025 - 11:05 AMI think Prof Leonard Susskind's videosdescribes the holographic principle best. A 3d objects entropy is described by its surface area (2d), not its volume (3d)

02/20/2025 - 11:05 AMIt is like deleted information on a hard drive, it is gone but yet it is still there until it is replaced.

@peterdamen2161
02/20/2025 - 11:05 AMThere are a lot of maybe's in this short video. Maybe this is all nonsense. For starters, we have no idea what an event horizon is and the idea that all the things that were falling inside a black hole were somehow captured in a preserved image at the event horizon itself is not based on any physical facts.

02/20/2025 - 11:05 AMDavid grush said we have UFO’s here on earth that we are currently studying that use this very technology. They can project from 4D to 3D or vice versa using this holographic principal.
@MMJ5280
02/20/2025 - 11:05 AMRather than a projection, it would seem that if a object enters into a black hole it is not destroyed but rather is spit out on the other side to reform itself. When we see in a telescope the beginnings of a star or a galaxy, perhaps that beginning is as a result of going through a black hole. It may be that stars and galaxies are shallowed up by different size black holes. Birthing stations or the foundation of infinity.

02/20/2025 - 11:05 AMis this Holographic the Lawh Mahfudz mentioned in the Quran? That is a "Book" which contains all of God's decrees from the beginning of the creation of the universe until the end of the day.
