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.

Scale of the Universe revisits “Powers of Ten”

Posted by in categories: astronomy, cosmology, physics, space travel

As a follow-up to Shailesh Prasad’s thought provoking video (just below this article), I offer two equally impressive visualizations of the scope and magnificence of our universe. These videos are the epitome of a teachable moment. And it’s fun, too!

Check out this simple, one-button interactive Scale of the Universe by Cary Huang. Simply pull a slider left or right to zoom in or out. It covers the Universe from 1027 meters down to 10-35 meters (from the entire universe to the Plank length and quantum foam).

Unlike the classic film by Charles & Ray Eames (more about that later), the zoom doesn’t really take viewers closer or further away. Rather, it compares relative size by allowing users navigate by magnitudes (a circle indicates each power-of-ten).

Why Physicists Are Saying Consciousness Is A State Of Matter, Like a Solid, A Liquid Or A Gas

Posted by in categories: neuroscience, physics

A new way of thinking about consciousness is sweeping through science like wildfire. Now physicists are using it to formulate the problem of consciousness in concrete mathematical terms for the first time.

New General Relativity Area law theory suggests time runs backward inside a blackhole

Posted by in categories: cosmology, physics

Black holes are known to have many strange properties, such as that they allow nothing—not even light—to escape after falling in. A lesser known but equally bizarre property is that black holes appear to “know” what happens in the future in order to form in the first place. However, this strange property arises from the way in which black holes are defined, which has motivated some physicists to explore alternative definitions.

They reported a new area law in general relativity that is based on an interpretation of black holes as curved geometric objects called “holographic screens.”

“The so-called teleology of the black hole event horizon is an artifact of the way in which physicists define an event horizon: the event horizon is defined with respect to infinite future elapsed time, so by definition it ‘knows’ about the entire fate of the universe,” Engelhardt told Phys.org. “In general relativity, the black hole event horizon cannot be observed by any physical observer in finite time, and there isn’t a sense in which the black hole as an entity knows about future infinity. It is simply a convenient way of describing black holes.”

“Addressing a current controversy in physics about information in black holes, “I propose that the information is stored not in the interior of the black hole as one might expect, but on its boundary, the event horizon.””
