Astronomers Identify a Signature of Dark Matter Annihilation

Posted by in categories: cosmology, particle physics

By studying the spatial distribution of gamma-ray emission in the Milky Way, astronomers believe they have identified a signature of dark matter annihilation.

We live in a dramatic epoch of astrophysics. Breakthrough discoveries like exoplanets, gravity waves from merging black holes, or cosmic acceleration seem to arrive every decade, or even more often. But perhaps no discovery was more unexpected, mysterious, and challenging to our grasp of the “known universe” than the recognition that the vast majority of matter in the universe cannot be directly seen. This matter is dubbed “dark matter,” and its nature is unknown. According to the latest results from the Planck satellite, a mere 4.9% of the universe is made of ordinary matter (that is, matter composed of atoms or their constituents). The rest is dark matter, and it has been firmly detected via its gravitational influence on stars and other normal matter. Dark energy is a separate constituent.

Understanding this ubiquitous yet mysterious substance is a prime goal of modern astrophysics. Some astronomers have speculated that dark matter might have another property besides gravity in common with ordinary matter: It might come in two flavors, matter and anti-matter, that annihilate and emit high energy radiation when coming into contact. The leading class of particles in this category are called weakly interacting massive particles (WIMPS). If dark matter annihilation does occur, the range of options for the theoretical nature of dark matter would be considerably narrowed.

For first time, drone delivers package to residential area

Posted by in categories: drones, food, robotics/AI

RENO, Nev. (AP) — A Nevada firm says one of its drones has successfully completed the first fully autonomous package delivery in a residential area in the U.S.

Flirtey CEO Matt Sweeney says the six-rotor drone flew about a half-mile along a pre-programmed delivery route on March 10. It lowered the package outside a vacant residence in an uninhabited area of Hawthorne, southeast of Reno. The route was established using GPS. A pilot and visual observers were on standby during the flight but weren’t needed.

The package included bottled water, food and a first-aid kit.

- teleportation exists.

Bye with the help of virtual / augmented reality. Read! Is shocking and heartbreaking.

In fact: within the framework of the project points is augmented reality, Microsoft Hololens started laboratory technology called holoportation.

Fear Not The Drone Apocalpyse

Posted by in categories: 3D printing, drones, geopolitics, robotics/AI, transhumanism

When the apocalypse comes, it won’t do so on four rotors. Drones, especially drones-as-we-know-them—the affordable, commercially available quadcopters—are only really engines of their own destruction. Zoltan Istvan, transhumanist candidate for President, wrote today that the American constitution is unprepared for the challenges of swarming robots. With all due I respect, I couldn’t possibly disagree more.

The Second Amendment Isn’t Prepared for a 3D-Printed Drone Army”, Istvan argues, and vividly sets a scene of total despair:

Physicists demonstrate a quantum Fredkin gate

Posted by in categories: computing, quantum physics

Researchers from Griffith University and the University of Queensland have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally realising a challenging circuit—the quantum Fredkin gate—for the first time.

“The allure of quantum computers is the unparalleled processing power that they provide compared to current technology,” said Dr Raj Patel from Griffith’s Centre for Quantum Dynamics.

“Much like our everyday computer, the brains of a quantum computer consist of chains of logic gates, although quantum logic gates harness quantum phenomena.”
