Much research on black holes is theoretical since it is difficult to make actual measurements on real black holes. Such experiments also need to be undertaken over decades or longer. Physicists are therefore keen to create laboratory systems that are analogous to these cosmic entities. New theoretical calculations by a team in Canada, the US, UK and Israel have now revealed that a material as simple as a graphene flake with an irregular boundary subjected to an intense external magnetic field can be used to create a quantum hologram that faithfully reproduces some of the signature characteristics of a black hole. This is because the electrons in the carbon material behave according to the Sachdev-Ye-Kitaev model.

Some of the most important unresolved mysteries in modern physics come from the “incompatibility” between Einstein’s theory of general relativity and the theory of quantum mechanics. General relativity describes the physics of the very big (the force of gravity and all that it affects: spacetime, planets, galaxies and the expansion of the Universe). The theory of quantum mechanics is the physics of the very small – and the other three forces, electromagnetism and the two nuclear forces.

“In recent years, physicists have gleaned important new insights into these questions through the study of the SYK model,” explains Marcel Franz of the University of British Columbia in Canada, who led this research effort. “This model is an illustration of a type of ‘holographic duality’ in which a lower-dimensional system can be represented by a higher dimensional one. In our calculations, the former is N graphene electrons in (0+1) dimensions and the latter the dilation gravity of a black hole in (1+1) dimensional anti-de Sitter (AdS₂) space.

The holographic display of the future is here and you can have one on your desk for under $600.

Ever since I saw Princess Leia appealing to Obi Wan that he was her only hope when I was 11, I’ve wanted a holographic display. Movies like Minority Report and Back to the Future II (do you remember the shark hologram that ate Marty?) have consumed thousands of people’s lives over the past few decades. But until now, no one has been able to make a scalable device that would let groups of people, unaided by a VR or AR headset, see and touch a living and moving 3D world.

That’s changing today with the launch of the Looking Glass, a new type of interface that achieves that dream of the hologram we’ve been promised for so long. The Looking Glass is technically a lightfield and volumetric display hybrid, but that’s pretty nerdy-sounding. I like to just call it a holographic display.

ELON MUSK wants to plump humans on Mars by 2024 and the first batch of settlers could live in 3D-printed home pods that pack hologram computers.

You’ll be able to tour the Red Planet habitat in virtual reality and view a scale model of the sci-fi living space at the Goodwood Festival of Speed next month.

In a profound talk about technology and power, author and historian Yuval Noah Harari explains the important difference between fascism and nationalism — and what the consolidation of our data means for the future of democracy. Appearing as a hologram live from Tel Aviv, Harari warns that the greatest danger that now faces liberal democracy is that the revolution in information technology will make dictatorships more efficient and capable of control. “The enemies of liberal democracy hack our feelings of fear and hate and vanity, and then use these feelings to polarize and destroy,” Harari says. “It is the responsibility of all of us to get to know our weaknesses and make sure they don’t become weapons.” (Followed by a brief conversation with TED curator Chris Anderson)

One of the enduring sci-fi moments of the big screen—R2-D2 beaming a 3D image of Princess Leia into thin air in “Star Wars”—is closer to reality thanks to the smallest of screens: dust-like particles.

Scientists have figured out how to manipulate nearly unseen specks in the air and use them to create 3D images that are more realistic and clearer than holograms, according to a study in Wednesday’s journal Nature. The study’s lead author, Daniel Smalley, said the new technology is “printing something in space, just erasing it very quickly.”

Why aren’t holograms or related optical devices part of our everyday lives yet? The technologies can be created by using magnetic fields to alter the path of light, but the materials that can do that are expensive, brittle and opaque. Some only work in temperatures as cold as the vacuum of space.

A new technique for recording image information onto a surface creates the ability for one space to contain multiple holographic snapshots, depending on how you look at it.

With this new research, cramming numerous holograms without loss of resolution on the same material could open the way to some fascinating new applications.

Holograms have been around for over half a century, serving as art, entertainment, and foils to counterfeiting. It’s been a hard and fast rule that no matter which way you view a hologram, the same object would appear in three dimensions. Until now.

As fast as fiber optic lines have become, they’re still hamstrung by one key limitation: you still need to transmit that data over wires, which limits where you can transmit and the affordability of the fastest connections. Scientists may have a way to eliminate those cables while offering even faster speeds, though. They’ve discovered a way to ‘twist’ photons in a way that not only crams more data into each transmission, but survives interference from turbulent air. If you pass light through a special hologram, you can give photons an optical angular momentum that lets them carry more than just 1s and 0s — and so long as the light’s phase and intensity are right, you can reliably beam that data over long distances.

The research team successfully tested just such a link over a 1-mile stretch in Germany, making sure that it took place in an urban environment where the turbulence from taller buildings could theoretically cause chaos.

There’s still a lot of work to be done before this kind of wireless networking is practical. How do you serve a large number of people, and how is data affected by rain or snow? Still, it’s promising. The technology is clearly limited by the challenges of transmitting light (you couldn’t use this to transmit indoors, for obvious reasons), but it could be instrumental to the next generation of last-mile wireless networks. Instead of having to painstakingly wire homes and offices to achieve multi-gigabit speeds, internet providers could use light-based wireless links for large parts of their network and install cabling only when it’s absolutely necessary.
