NASA Virtually Teleports Doctor Hundred of Miles In Space To Show Off ‘Holoportation’

Posted by in categories: augmented reality, biotech/medical, holograms, virtual reality

In a remarkable development, the National Aeronautics and Space Administration (NASA) ‘holoported’ the first human being into space late last year. Holoportation is the process through which a three dimensional holographic representation of an individual is created, in a combination of a ‘hologram’ and ‘teleportation’. NASA revealed the development late last week, as it announced that it had transported flight surgeon Dr. Josef Schmid, mixed and virtual reality firm AEXA Aerospance’s chief executive officer Dr. Fernando De La Pena Llaca and others to the International Space Station (ISS) during October 2021 while the ISS was orbiting the Earth at an altitude of 250 miles above the Earth’s surface.

The event place last year when NASA’s Crew 2 astronauts were present on the ISS. The astronauts took to the skies in April last year and returned in November, soon after Dr. Schmid and others were holoportated to the orbiting space laboratory.

What’s Inside a Black Hole? Physicist Probes Holographic Duality With Quantum Computing To Find Out

Posted by in categories: cosmology, holograms, mathematics, particle physics, quantum physics, robotics/AI

Dude, what if everything around us was just … a hologram?

The thing is, it could be—and a University of Michigan physicist is using quantum computing and machine learning to better understand the idea, called holographic duality.

Holographic duality is a mathematical conjecture that connects theories of particles and their interactions with the theory of gravity. This conjecture suggests that the theory of gravity and the theory of particles are mathematically equivalent: what happens mathematically in the theory of gravity happens in the theory of particles, and vice versa.

Scientists Are Data Mining Black Holes to See If They Are Holograms

Posted by in categories: cosmology, holograms, quantum physics, robotics/AI

There are few places in the universe that invite as much curiosity—and terror—as the interior of a black hole. These extreme objects exert such a powerful gravitational pull that not even light can escape them, a feature that has left many properties of black holes unexplained.

Now, a team led by Enrico Rinaldi, a research scientist at the University of Michigan, have used quantum computing and deep learning to probe the bizarre innards of black holes under the framework of a mind-boggling idea called holographic duality. This idea posits that black holes, or even the universe itself, might be holograms.

Hybrid work is here to stay. Activating your hologram may be the next way to enter a meeting

Posted by in category: holograms

Lister says during this talent shortage, companies are going to need to meet the demands of workers, which will likely include a hybrid model.

Her research found that 56% of U.S. workers have a job that can be done at least partially remotely. She says allowing employees to shift their hours, which days they work, and even when they take a break can have a huge impact on retention.

Technology will have an outsized role in how companies implement their hybrid models. Lister says that within five years, employees may be able to meet via hologram instead of through a video call.

Symmetries Reveal Clues About the Holographic Universe

Posted by in categories: holograms, quantum physics

We’ve known about gravity since Newton’s apocryphal encounter with the apple, but we’re still struggling to make sense of it. While the other three forces of nature are all due to the activity of quantum fields, our best theory of gravity describes it as bent space-time. For decades, physicists have tried to use quantum field theories to describe gravity, but those efforts are incomplete at best.

One of the most promising of those efforts treats gravity as something like a hologram — a three-dimensional effect that pops out of a flat, two-dimensional surface. Currently, the only concrete example of such a theory is the AdS/CFT correspondence, in which a particular type of quantum field theory, called a conformal field theory (CFT), gives rise to gravity in so-called anti-de Sitter (AdS) space. In the bizarre curves of AdS space, a finite boundary can encapsulate an infinite world. Juan Maldacena, the theory’s discoverer, has called it a “universe in a bottle.”

But our universe isn’t a bottle. Our universe is (largely) flat. Any bottle that would contain our flat universe would have to be infinitely far away in space and time. Physicists call this cosmic capsule the “celestial sphere.”
