The desire to make people and objects invisible is old. Various experiments have been developed for decades. However, the most recent one seems to have hit the mark: an invisibility cloak created by Chinese professor Chu Junhao, director of the Faculty of Science at Donghua University in Shanghai.

In a public event, reported on social networks, the academic showed the properties of the new material, when two assistants displayed before him a transparent plate that immediately made his body invisible from the waist down.

As if it were Harry Potter’s invisibility cloak, the material used allowed the lower part of his body to disappear from view. But how does it actually work?

Chu Junhao has noted that “invisibility was achieved with a series of templates or lenticular grids. These are a kind of transparent sheets made up of tiny convex cylindrical lenses. When light passes through this outstanding material, a refraction phenomenon occurs that erases the image from the visual field.”

At that moment, “the material will cause the light to be compressed into thin strips and when the number of lenses is large enough, invisibility occurs.”

When this point has been reached, the image we perceive breaks down into millions of identical particles, making it impossible for the human eye to capture the set of elements. It is as if what was in front of the viewer has disappeared.

Although the professor at Donghua University in Shanghai defends the application of this layer in the military area, to disappear airplanes, for example, he also points out that it could soon become another piece in our closet.

Technological developments have opened the door to the possibility that Harry Potter's invisible cloak could go from magic to reality.

Science fiction writer Neal Stephenson wants to create an open metaverse based on blockchain technology, with which he hopes to achieve a decentralized virtual ecosystem through the Lamina1 project.

Stephenson is responsible for the term metaverse, which he coined in his 1992 novel Snow Crash, to refer to cyberspace, although he also popularized others that are very common today, such as avatars and massive online role-playing games (MORPGs).

The writer now seeks to create a blockchain-based metaverse through the Lamina1 project, of which he is a co-founder, which will act as “the meeting point” of an ecosystem of resources and open standards and of “technologies conceived and developed jointly with a vibrant community of creators”.

Contrary to the metaverse that companies like Meta seek to build, Stephenson’s proposal will take advantage of the decentralization offered by blockchain and Web3 to be open; It will offer open data and payment protocols and a set of interoperable services that support virtual worlds, as explained in the presentation document of Lamina1.
