The Surprising Reason Toyota Just Patented a 'Cloaking Device'

The Japanese auto maker is developing a device that would improve visibility for motorists. From cloaking devices that conceal spaceships, to Harry Potter’s hand-me-down disappearing blanket, or even the One Ring and its power to conceal its wearer, invisibility is a staple in science fiction and fiction in general. Scientists have been hard at work, however, to bring such a technology into reality. Joining the research and development of cloaking technology is Japanese car manufacturer Toyota. The company recently acquired a patent from the United States Patent and Trademark Office (USPTO) for “Apparatuses and methods for making an object appear...

How could we build an invisibility cloak to hide Earth from an alien civilization?

What would it take to hide an entire planet? It sounds more like a question posed in an episode of “Star Trek” than in academic discourse, but sometimes the bleeding edge of science blurs with themes found in science fiction. Of course we’ve been leaking our own position to distant stars via radio and television signals for six decades now, largely ignorant of the cosmic implications. But several notable scientists, such as Stephen Hawking, have publicly voiced concerns about revealing our presence to other civilizations. These concerns largely draw from the darker chapters of our own history, when a more...

Laser cloaking device could hide Earth from aliens

Powerful lasers could be used by astronomers to prevent aliens from discovering Earth according to two astronomers at Columbia University in New York. Several prominent scientists, including Stephen Hawking, have cautioned in the past against humanity broadcasting its presence to intelligent life on other planets. It is thought that other civilisations could find Earth-like planets using the same techniques that we do, searching for the dip in light when a planet moves directly in front of the star it orbits. This process constitutes the main way that the Kepler mission and similar projects search for planets around other stars; it...

Mysterious People Who Appeared from Nowhere

History is rife with strange tales of people who have mysteriously vanished from the face of the earth without a trace, but one area that seems to get decidedly less coverage is the various accounts of those who did just the opposite, appearing out of nowhere cloaked in mystery and emanating questions and puzzles around them that have never been satisfactorily answered. Here we have strangers who have stepped out of thin air from another place, perhaps even another time or plane of existence, and have gone on to leave impenetrable mysteries in their wake to this day. Stepping out...

Scientists unveil 'Cloaking Device' to rival Harry Potter's

Scientists at the University of Rochester have discovered a way to hide large objects from sight using inexpensive and readily available lenses, a technology that seems to have sprung from the pages of J.K. Rowling's Harry Potter fantasy series. Cloaking is the process by which an object becomes hidden from view, while everything else around the cloaked object appears undisturbed. "A lot of people have worked on a lot of different aspects of optical cloaking for years," John Howell, a professor of physics at the upstate New York school, said on Friday. The so-called Rochester Cloak is not really a...
