New Dark Matter Theory Weighs Superheavy Particle

Posted by in categories: particle physics, space

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests.

While dark matter is thought to make up five-sixths of all matter in the universe, scientists don’t know what this strange stuff is made of. True to its name, dark matter is invisible — it does not emit, reflect or even block light. As a result, dark matter can currently be studied only through its gravitational effects on normal matter. The nature of dark matter is currently one of the greatest mysteries in science.

If dark matter is made of such superheavy particles, astronomers could detect evidence of them in the afterglow of the Big Bang, the authors of a new research study said. [Dark Matter Explained (Infographic)].

Remarkable nanowires could let computers of the future grow their own chips

Posted by in categories: computing, engineering, materials, mobile phones, nanotechnology, particle physics, robotics/AI

Now, we’re hitting Terminator mode with this.


If you’re worried that artificial intelligence will take over the world now that computers are powerful enough to outsmart humans at incredibly complex games, then you’re not going to like the idea that someday computers will be able to simply build their own chips without any help from humans. That’s not the case just yet, but researchers did come up with a way to grow metal wires at a molecular level.

At the same time, this is a remarkable innovation that paves the way for a future where computers are able to create high-end chip solutions just as a plant would grow leaves, rather than having humans develop computer chips using complicated nanoengineering techniques.

Using machine learning to rationally design future electronics materials

Posted by in categories: computing, information science, materials, particle physics, robotics/AI, singularity, solar power, sustainability

Even if we don’t create a true AI for a thousand years, these algorithms, pared with our exponentially increasing computing power, could have much of the same effect on our civilization as the more traditional, AI-centric type Singularity. Very, very soon.

Replacing inefficient experimentation, UConn researchers have used machine learning to systematically scan millions of theoretical compounds for qualities that would make better materials for solar cells, fibers, and computer chips.

There’s No Cloning in Quantum Mechanics, So the Star Trek Transporter Really Is a Suicide Box

Posted by in categories: health, particle physics, quantum physics

Yesterday, a report came from a tech company in Asia that they are proposing to do Quantum teleporting on humans. So, we have that camp; today we have the other camp with this article stating to do so means death. Personally, I have my doubts around humans or animals of any sort being able to teleport like Star Trek; great concept. However, to do so means breaking down your make up into particles and hopefully without killing you, the particles transport and reassemble themselves and everything remains healthy and functioning. Wish the test subjects all the best.


Remember last week’s video about the trouble with Star Trek’s transporter (a.k.a. a “suicide box”) by CGP Grey, delving into whether the teleported version of yourself would really be, well, you? Henry Reich of Minute Physics has posted a video response with his own resolution to the logical paradox.

Quantum Computers And Their Applications [INFOGRAPHIC]

Posted by in categories: computing, particle physics, quantum physics, robotics/AI

Interesting position that IBM is taking with Quantum Computing. The one challenge that was highlighted in this article around unstable particles actually has been in the process of being resolved by Charles Marcus and colleagues at the University of Copenhagen’s Niels Bohr Institute; Univ. of Copenhagan’s report came out a few weeks ago and it may be a good thing for IBM to connect with the University so they can see how this was resolved.

Also, I don’t believe that we have 3 uniquely different platforms of Quantum as this article highlights. Trying to state that a D-Wave Quantum Computer is not a full Quantum platform or less of a Quantum Platform to is not a fair statement; and I encourage others to pull back from that perspective at this point until Quantum Computing is more evolved and standards around the platform is well defined and approved by industry. Also, the Gartner graph in this article is not one that I embraced given the work on Quantum is showing us the we’re less than 10 yrs away for it in the mainstream instead of Gartners graph showing us Quantum will require more than 10 years to hit the mainstream. And, I saw some of missed marks on Bio-sensors and BMI technology taking more than 10 years on the Gartner graph which is also incorrect since we hearing this week announcements of the new bio-chips which enables bio-sensors and BMIs are making some major steps forward with various devices and implants.

The ‘great smoky dragon’ of quantum physics

Posted by in categories: nanotechnology, particle physics, quantum physics

Abstract: Since the 17th century, science was intrigued by the nature of light. Isaac Newton was certain that it consists of a stream of particles. His contemporary Christiaan Huygens, however, argued that light is a wave. Modern quantum physics says that both were right. Light can be observed both as particles and as waves — depending which characteristic is measured in an experiment, it presents itself more as one or the other. This so-called wave-particle dualism is one of the foundational principles of quantum physics. This questions our common sense: can one and the same indeed be of two contradictory natures at the same time?
