3-D TV in the future made possible by artificial ‘wormholes’ International mathematicians create wormhole construction model

26.11.2007
Matti Lassas, Professor in Mathematics, who works in the Academy of Finland’s Centre of Excellence in Inverse Problems at Helsinki University of Technology, is part of the research team. The team’s method has been published in Physical Review Letters.

A wormhole is a concept used in the theory of relativity that describes shortcuts between two points running outside ordinary space. The term ‘wormhole’ comes from a playful assertion that a worm on an apple will get from one side to the other faster by burrowing through it than by crawling over the surface.

Previously, this same group of mathematicians studied the invisibility cloak theory. The invisibility cloak theory involves sheathing an object with an exotic material so that the light striking the sheathed object moves around it, thus making the object appear to be invisible when viewed from a distance.

The new proposal for the construction of wormholes corresponds with cloaking a pipe to make it invisible. In such a case, the front and back ends of the pipe would ostensibly be connected by an invisible tunnel. This artificial wormhole could be thought of in the same terms as the sleeve of Harry Potter’s invisibility cloak, through which objects could be passed from one end to the other without being seen.

Wormholes can be built using metamaterials

The new materials required to construct invisibility cloaks and artificial wormholes, called ‘metamaterials’ are currently the subject of active research. At present, they can, in practice, be constructed for only very limited applications within the range of visible light. A metamaterial designed for use in a microwave invisibility cloak was produced in 2006 at Duke University in the United States by a research team under the direction of Professor David Smith.

Similar materials are suitable for constructing artificial wormholes at microwave frequencies. The construction of a three-dimensional TV would require producing similar materials that work at visible light wavelengths, which, in turn, would require highly advanced nanotechnology. In the near future, artificial wormhole applications will be used in radar technologies and medical imaging.

For example, in MRI (Magnetic Resonance Imaging), which is used by hospitals for the imaging of patients, an artificial wormhole could be used as a shielding tunnel, through which instruments could be passed to the area being imaged without causing interference in the imaging itself.

Professor Matti Lassas’ partners in the development of artificial wormholes are Professors Allan Greenleaf of the University of Rochester, Yaroslav Kurylev of University College London and Gunther Uhlmann of the University of Washington.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
