How Do Holograms Work?

When you look at a hologram—for example, the one on your credit card—you'll notice that it is a seemingly three-dimensional image mapped onto a two-dimensional surface. Proponents of the holographic principle suspect that information normally thought to be "lost" after falling into black hole, is merely transcribed onto its surface. Physicists believe that, like holographic film viewed under a microscope, this information is indecipherable, but there. Leonard Susskind explains.

The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

he made that with Microsoft paint? WOW! he must be a very patient man.

[thechosenone]

Still doesn't explain how holograms work.

[ditchweed]

He says information is scrambled all over the film. That's a false description because any segment of the film contains the entire image/all information. It's nonlocal. Information is nonlocal. They just can't deal with it because they don't actually know how it works. So they ignore the elephant in the room.

God... the host couldn't shut his trap so the guest could explain

[atmel]

False title. This video does explain what are holograms but does neither explain how they are created nor how can the 3D image be reconstructed from an interference pattern.

[keith.anthony.infinity.h]

If a hologram is nothing but an interference pattern being made into a 3-d image, could the collapse of an electron’s wave-function inference pattern be thought of as a hologram?

it is interesting to imagine life, reality like this, like a hologram, like a matrix. Just like information is stored to create computer, vídeo games, that create the sense of depthness, of mechanics, of light, the universe itself may be like this too. An infinite amount ou information stored somewhere forming what we perceive as time and space, creating the illusion of depth, time, etc. This is a very interesting concept, it even supports the time travel theory, because, once the information of the universe is stored somewhere, it can be recreated, if they come back to be interpreted, in the state they were before. If this is true, then future can also be created, developing the way information is stored and is affected, the upcoming information must also be somewhere stored, only "waiting" to be interpreted! the way we perceive things and the reality may be a illusion, just as the concept of space and time. All this information can be stored somewhere, in an extradimensional field. What am i saying? I don't know, just playing with my thoughts!

Never knew Mike Ehrmantraut also had a technical side apart from the hit man experience.

[capmoman]

2:39 -- *"Impossible to UNDERSTAND"* -> WOW!! I understand it now!

[Reticuli]

I heard someone just say that all holograms are fractals. I know that fractals can also be holograms, but I've never heard the former. If you zoom into the clown's eyebrow close enough you see another clown? I've never heard such a thing.

[guenterlohnert]

Are they serious, or are they trying to pull my leg?

[kokomanation]

we may be some kind of simulated conscious beings

[abaldeagle]

Who is here because of project blue beam?

[clearwavepro]

what was the point of these people discussing this? It was more like a sales pitch, with extreme, supposition (true or not). and with giving almost no meaning, and suggesting absolutely no virtue or purpose to the suggested description's value, NOR any virtue or purpose to the universe itself's reasoning for having been designed as suggested here.

not good.

[Li-bntw]

These scientists are so annoying. They made bouncy of niose till half of the clip then throw some unimportant stuff.

[clintpot]

Awful waste of time. Two guys cracking jokes when the implications of holographic structures have vast implications on our species.
