As the April 23rd French presidential election approaches, candidates are predictably stumping to bring voters out, but far-left candidate Jean-Luc Mélenchon may have the most effective strategy: using an optical illusion, he beamed “holograms” of himself to six cities around the country.

As Le Parisien reports, Mélenchon, who is often compared to Bernie Sanders, uses a technique known as Pepper’s Ghost (and not technically a hologram) to broadcast a 2-D version of himself. From Dijon, he simultaneously appeared in seven places at once yesterday.

Black holes are one of the most mysterious objects astronomer have encountered so far. And a new study proposes that black are nothing but just a holographic projection, with a new calculation of the entropy — or also known as disorder. These calculations suggest that these giant enigmas of the Universe being nothing but an optical illusion. Holograph hypothesis was first proposed by physicist Leonard Susskind back in the 1990s, according to this theory, mathematically speaking, the Universe requires just two dimensions — not three — for the laws of physics and gravity to work as they really should.

A BONKERS Russian billionaire claims he’ll make you immortal by 2045.

Internet businessman Dmitry Itskov, 38, is bankrolling a far-fetched plan to uploaded people’s personalities to artificial brains.

These “brains” can then be jammed into robots or holograms, allowing us to live on forever as artificial versions of ourselves, Dmitry claims.

Water is special even based on its simple physical properties since it is the only substance on earth that can be found in all three states (liquid, solid, gas). However, scientists at the US Department of Energy Oak Ridge National Laboratory (ORNL) have discovered new properties of water that go beyond the known laws of classical physics says the phys.org scientific news portal.

The use of ultrasound waves allows the device to produce audible noise as well as a physical sensation.

“Even if not audible to us, ultrasound is still a mechanical wave and it carries energy through the air,” researcher Diego Martinez Plasencia said in the press release. “Our prototype directs and focuses this energy, which can then stimulate your ears for audio, or stimulate your skin to feel content.”

The researchers envision future versions of the device making use of multiple beads to create even more detailed holograms. And perhaps even more exciting than the prototype itself is the fact that, unlike many cutting-edge technologies, this one might not have too much difficulty making the leap to consumer product.

Walking, talking holograms have been a staple of sci-fi films since Princess Leia was magically brought to life in “Star Wars”.

Now scientists in Britain say they can make even more realistic 3D versions—a butterfly, a globe, an emoji—which can be seen with the , heard and even felt without the need for any .

Writing in the journal Nature, a team at the University of Sussex in southern England, said technology currently in use can create 3D images but they are slow, short-lived and “most importantly, rely on operating principles that cannot produce tactile and auditive content as well”.

Researchers have developed a new printer that produces digital 3D holograms with an unprecedented level of detail and realistic color. The new printer could be used to make high-resolution color recreations of objects or scenes for museum displays, architectural models, fine art or advertisements that do not require glasses or special viewing aids.

“Our 15-year research project aimed to build a printer with all the advantages of previous technologies while eliminating known drawbacks such as expensive lasers, slow speed, limited field of view and unsaturated colors,” said research team leader Yves Gentet from Ultimate Holography in France. “We accomplished this by creating the CHIMERA printer, which uses low-cost commercial lasers and high-speed printing to produce holograms with high-quality color that spans a large dynamic range.”

In The Optical Society (OSA) journal Applied Optics, the researchers describe the new printer, which creates holograms with wide fields of view and full parallax on a special photographic material they designed. Full parallax holograms reconstruct an object so that it is viewable in all directions, in this case with a field of view spanning 120 degrees.
