The men claimed they were abducted

Posted by in categories: biotech/medical, quantum physics

As an experiencer, I believe most claims are real. Whether they were man-made or actual exterrestials or exterrestials that work with us it is still a very common phenomenon. There have been several sightings essentially where even the person’s shoes were the only things left. Looking from common science fiction even it is a possibility that Emelia Airhart was teleported by aliens somewhere in the galaxy and can be referenced from the reports on star trek the tv show. There are several missing people that even today with good forensics that hardly anyone can find and the oddity of it all essentially says that essentially there were no traces left like literally none not even DNA. Looking through police records sure there are cold cases but most are solved but there are several cases that even the highest technologies of forensics have not solved. There are several cold cases all around the globe that were not ordinary ones they were, in fact, alien signs. But eventually, with quantum radar we could scan the entire universe to eventually find traces and digitize them finding a sorta batman style way of like forensics but you would need massive hardware but eventually, you could find them or anything in time. If they found Emelia Airhart they will find anyone else if these exist on this universe or even the multiverse if they physically exist. Then they would actually prove that aliens do actually exist aswell. Really nothing is impossible only improbable. Believing in aliens is not as far fetched as it seems. Most of their technology is science-based anyway it is just exotic physics.


The site of the 1973 alleged abduction is getting a historical marker.

It From Bit — Entropic Gravity For Pedestrians

Posted by in categories: cosmology, information science, quantum physics

Two and a half months since Erik Verlinde submitted his entropic gravity paper, and all of physics and cosmology has turned into entropy. Well, I am exaggerating a bit, and perhaps more than just a bit. Yet, fact is that within two weeks of Erik’s publication a steady stream of ‘entropic everything’ papers has developed at a rate of close to one paper per day. Gravity, Einstein’s equations, cosmic expansion, dark energy, primordial inflation, dark mass: it’s all entropic. Chaos rules. Entropy is king!

Or is it?

Could it be that an ‘entropic bandwagon’ has started rolling? Is this all not just a fad appealing to scientist tired of string theory? What is this elusive entropic force anyway? Do these folks really believe bits of information attract each other?

Squeeze leads to stellar-mass black hole collision precision

Posted by in categories: cosmology, quantum physics

Scientists at The Australian National University (ANU) have found a way to better detect all collisions of stellar-mass black holes in the universe.

Stellar-mass black holes are formed by the gravitational collapse of a star. Their collisions are some of the most violent events in the universe, creating or ripples in space-time.

These ripples are miniscule and detected using laser interferometers. Until now, many signals have been drowned out by so-called on the pushing the mirrors of the laser interferometer around—making the measurements fuzzy or imprecise.

The Race For Quantum Supremacy I VICE on HBO

Posted by in categories: biotech/medical, cybercrime/malcode, quantum physics

Computer giants are racing to build the first quantum computer, a device with millions of times more processing strength than all the computers currently on Earth combined. This technology will harness the unusual laws of quantum mechanics to bring unimaginable advances in fields like materials science and medicine, but could also pose the greatest threat to cybersecurity yet. VICE’s Taylor Wilson meets the scientists at the cutting edge of this new age of computing.

Evading Heisenberg isn’t easy

Posted by in categories: particle physics, quantum physics

EPFL researchers, with colleagues at the University of Cambridge and IBM Research-Zurich, unravel novel dynamics in the interaction between light and mechanical motion with significant implications for quantum measurements designed to evade the influence of the detector in the notorious ‘back action limit’ problem.

The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years, e.g. in the first direct observation of , which were manifested as tiny displacements of mirrors in kilometer-scale optical interferometers. On the microscopic scale, atomic- and magnetic-resonance force microscopes can now reveal the atomic structure of materials and even sense the spins of single atoms.

But the that we can achieve using purely conventional means is limited. For example, Heisenberg’s uncertainty principle in implies the presence of “measurement backaction”: the exact knowledge of the location of a particle invariably destroys any knowledge of its momentum, and thus of predicting any of its future locations.

Scientists Predict Quantum Jumps, Turning Physics on Its Head

Posted by in categories: computing, quantum physics

In 1935, physicist Erwin Schrödinger concocted a thought experiment to illustrate a pair of strange quantum physics phenomena: superposition and unpredictability.

The experiment became known as Schrödinger’s cat, and for more than 80 years, it’s served as a cornerstone of quantum physics. But in a newly published study, a team of Yale scientists essentially destroys the premise at the center of the experiment — groundbreaking work that could finally allow researchers to develop useful quantum computers.

Researchers create quantum chip 1,000 times smaller than current setups

Posted by in categories: computing, information science, mobile phones, quantum physics, security

Researchers at Nanyang Technological University, Singapore (NTU Singapore) have developed a quantum communication chip that is 1,000 times smaller than current quantum setups, but offers the same superior security quantum technology is known for.

Most leading security standards used in secure communication methods—from withdrawing cash from the ATM to purchasing goods online on the smartphone—does not leverage quantum technology. The electronic transmission of the personal identification number (PIN) or password can be intercepted, posing a .

Roughly three millimeters in size, the tiny chip uses quantum communication algorithms to provide enhanced security compared to existing standards. It does this by integrating passwords within the information that is being delivered, forming a secure quantum key. After the information is received, it is destroyed along with the key, making it an extremely secure form of communication.

Faster, More Secure Communications Using Structured Light in Quantum Protocols

Posted by in categories: quantum physics, security

Structured light is a fancy way to describe patterns or pictures of light, but deservedly so as it promises future communications that will be both faster and more secure.

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. In AVS Quantum Science, from AIP Publishing, researchers from the University of Witwatersrand in South Africa review the progress being made in using structured light in quantum protocols to create a larger encoding alphabet, stronger security and better resistance to noise.

“What we really want is to do quantum mechanics with patterns of light,” said author Andrew Forbes. “By this, we mean that light comes in a variety of patterns that can be made unique — like our faces.”

Hard as ceramic, tough as steel: Newly discovered connection could help design of nextgen alloys

Posted by in categories: information science, nuclear energy, quantum physics, robotics/AI

A new way to calculate the interaction between a metal and its alloying material could speed the hunt for a new material that combines the hardness of ceramic with the resilience of metal.

The discovery, made by engineers at the University of Michigan, identifies two aspects of this interaction that can accurately predict how a particular alloy will behave—and with fewer demanding, from-scratch quantum mechanical calculations.

“Our findings may enable the use of machine learning algorithms for alloy design, potentially accelerating the search for better alloys that could be used in turbine engines and nuclear reactors,” said Liang Qi, assistant professor of materials science and engineering who led the research.
