Physicists create antimatter in record density

Posted by in category: physics

Positrons are plentiful in ultra-intense laser blasts

Physicists from Rice University and the University of Texas at Austin have found a new recipe for using intense lasers to create positrons — the antiparticle of electrons — in record numbers and density.

In a series of experiments described recently in the online journal Scientific Reports published by Nature, the researchers used UT’s Texas Petawatt Laser to make large number of positrons by blasting tiny gold and platinum targets.

Quantum Theory: ‘Spooky Action at a Distance’ confirmed

Posted by in categories: encryption, general relativity, physics, quantum physics, science

In one of my first articles for Lifeboat,* I provided an experimental methodology for demonstrating (or proving) the instantaneous ‘communication’ between quantum entangled particles. Even though changes to one particle can be provably demonstrated at its far away twin, the very strange experimental results suggested by quantum theory also demonstrate that you cannot use the simultaneity for any purpose. That is, you can provably pass information instantly, but you cannot study the ‘message’ (a change in state at the recipient), until such time as it could have been transmit by a classical radio wave.

Now, scientists have conducted an experiment proving that objects can instantaneously affect each other, regardless o the distance between them. [continue below]

Computer that could outlive the universe a step closer

Posted by in categories: computing, physics, space

The heat-death of the universe need not bring an end to the computing age. A strange device known as a time crystal can theoretically continue to work as a computer even after the universe cools. A new blueprint for such a time crystal brings its construction a step closer.

Ordinary crystals are three-dimensional objects whose atoms are arranged in regular, repeating patterns – just like table salt. They adopt this structure because it uses the lowest amount of energy possible to maintain.

Earlier this year, Frank Wilczek, a theoretical physicist at the Massachusetts Institute of Technology, speculated that a similar structure might repeat regularly in the fourth dimension – time.

Graphene nanoribbons as electronic highways

Physicists have developed a method to synthesise a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.

Stephen Hawking says nomadic aliens might crush us

Posted by in categories: alien life, physics

Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach,” Hawking told El Pais. “To my mathematical brain, the numbers alone make thinking about aliens perfectly rational. The real challenge is to work out what aliens might actually be like.”

It’s funny how math can make you paranoid. Even if it’s entirely reasonable paranoia. The discovery of water on Mars is, for the non-mathematical at least, the first indication that something out there might be alive or might once have been alive.”


Technically Incorrect: The famed physicist says that simple math makes him believe there are aliens out there.

Why ‘Alien Hunters’ See ‘Warp Drive’ As A SETI Nonstarter

Posted by in categories: alien life, physics, space travel

Why #SETI and Warp Drive don’t necessarily mix; although, I tend to think if #ET is out there it would have long figured out a way to manipulate spacetime for interstellar #FTL travel. It’s time mainstream #physics embraced the idea that Einstein’s axioms involving #lightspeed can be overcome. We’ve nothing to lose but lots to gain. Special thanks to Erika McGinnis for allowing me to publish her artwork.


For all the hype over the idea that someday, somehow we humans will voyage to the stars — not at a measly fraction of the speed of light — but several “warp” factors beyond light speed, it’s a prospect few physicists take seriously. Even mention of “warp drive” is borderline taboo in certain academic circles.

And the idea that Einstein’s Theory of Relativity and with it the axiom that the ultimate speed of light can never be violated is a tenet that most researchers who spend their time plying the nearby cosmos for artificial radio or laser beacons have taken to heart. It supports most SETI scientists’ long-held notion that Earth has never been visited by sentient extraterrestrials.

Stephen Hawking speaks with virtually no muscular movement

Posted by in categories: astronomy, biotech/medical, cosmology, gravity, physics, singularity, space, thought controlled

Next January Stephen Hawking will be 74 years old. He has lived much longer than most individuals with his debilitating condition. In addition to being an unquestionably gifted cosmologist, he has invited controversy by supporting the pro-Palestinian, Israel-BDS boycott and warning about the dangers of alien invaders who tap into our interstellar greetings

Antisemitism, notwithstanding, this man is a mental giant. He is Leonardo. He is Einstein. Like them, his discoveries and theories will echo for generations beyond his life on earth. He is that genius.


Forty years ago, when Stephen Hawking still had mobility, he delivered a paper on a mystery regarding information-loss for entities that cross the event boundary of a black hole.

In the mid 1970s, Astronomers were just discovering black holes and tossing about various theories about the event horizon and its effect on the surrounding space-time. Many individuals still considered black holes to be theoretical. Hawking’s analysis of the information paradox seemed extremely esoteric. Yet, last month (Aug 2015) , at Sweeden’s KTH Royal Institute of Technology, Hawking presented a possible solution to the paradox that he sparked.

Extending Galactic Habitable Zone Modeling to Include the Emergence of Intelligent Life — By Morrison Ian S. and Gowanlock Michael G. | Astrobiology

Previous studies of the galactic habitable zone have been concerned with identifying those regions of the Galaxy that may favor the emergence of complex life. A planet is deemed habitable if it meets a set of assumed criteria for supporting the emergence of such complex life. In this work, we extend the assessment of habitability to consider the potential for life to further evolve to the point of intelligence—termed the propensity for the emergence of intelligent life, φI.

Physicists develop key component for terahertz wireless

Posted by in categories: electronics, internet, mobile phones, physics

Terahertz radiation could one day provide the backbone for wireless systems that can deliver data up to one hundred times faster than today’s cellular or Wi-Fi networks. But there remain many technical challenges to be solved before terahertz wireless is ready for prime time.

Researchers from Brown University have taken a major step toward addressing one of those challenges. They’ve developed what they believe to be the first system for multiplexing terahertz waves. Multiplexers are devices that enable separate streams of data to travel through a single medium. It’s the technology that makes it possible for a single cable to carry multiple TV channels or for a fiber optic line to carry thousands of phone calls at the same time.
