We Might Already Speak the Same Language As ET
Posted by Jose Ruben Rodriguez Fuentes in categories: alien life, existential risks, mathematics, quantum physics
Alien communication could utilize quantum physics, so SETI needs a new way to listen.
The Fermi paradox, the “where is everybody?” puzzle, is a persistent question in the search for life in the universe. It asks why, if life is not exceedingly rare in the cosmos, it hasn’t shown up on our doorstep. Equally we might ask why we haven’t even heard from alien life, through radio signals or any other means. A part of the answer could be that our present work on the search for extraterrestrial intelligence is actually very limited. Estimates show that we’ve only examined the equivalent of a hot tub of water compared to all the world’s oceans in our combing through the electromagnetic information that rolls in from the cosmos.1
If you’re a glass-half-full kind of person you’ll see this as an opportunity, but the problem is that we don’t actually know what might be filling the glass in the first place. The vast majority of SETI studies look for structure in electromagnetic radiation, whether in amplitude or frequency modulations of radio waves, or regularity in pulses of light, or in multi-wavelength correlations. In other words, we assume that information might be sailing past us in representations built using classical physics. But what if that’s just wrong?

World’s Fastest 2-Qubit Gate: Breakthrough for the Realization of Ultrafast Quantum Computers
Posted by Shubham Ghosh Roy in categories: computing, particle physics, quantum physics
A research team succeeded in executing the world’s fastest two-qubit gate (a fundamental arithmetic element essential for quantum computing) using a completely new method of manipulating, with an ultrafast laser, micrometer-spaced atoms cooled to absolute zero temperature. For the past two decade.

Absolute zero is the theoretical lowest temperature on the thermodynamic temperature scale. At this temperature, all atoms of an object are at rest and the object does not emit or absorb energy. The internationally agreed-upon value for this temperature is −273.15 °C (−459.67 °F; 0.00 K).

NASA’s Fermi telescope confirms star wreck as source of extreme cosmic particles
Posted by Shubham Ghosh Roy in categories: cosmology, particle physics
Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place.
Fermi has shown that the shock waves of exploded stars boost particles to speeds comparable to that of light. Called cosmic rays, these particles mostly take the form of protons, but can include atomic nuclei and electrons. Because they all carry an electric charge, their paths become scrambled as they whisk through our galaxy’s magnetic field. Since we can no longer tell which direction they originated from, this masks their birthplace. But when these particles collide with interstellar gas near the supernova remnant, they produce a telltale glow in gamma rays—the highest-energy light there is.

New programmable 3D printed materials can sense their own movements
Posted by Shubham Ghosh Roy in categories: 3D printing, materials
MIT researchers have developed a method for 3D printing materials with tunable mechanical properties, that sense how they are moving and interacting with the environment. The researchers create these sensing structures using just one material and a single run on a 3D printer.
To accomplish this, the researchers began with 3D-printed lattice materials and incorporated networks of air-filled channels into the structure during the printing process. By measuring how the pressure changes within these channels when the structure is squeezed, bent, or stretched, engineers can receive feedback on how the material is moving.
The method opens opportunities for embedding sensors within architected materials, a class of materials whose mechanical properties are programmed through form and composition. Controlling the geometry of features in architected materials alters their mechanical properties, such as stiffness or toughness. For instance, in cellular structures like the lattices the researchers print, a denser network of cells makes a stiffer structure.

Super-Earth found ‘skimming’ habitable zone of red dwarf
Posted by Future Timeline in category: space
The discovery of a super-Earth around the red dwarf Ross 508 is reported by astronomers in Japan. Part of the planet’s elliptical orbit takes it within the star’s habitable zone, where liquid water may exist.

This cabin in the woods is an otherworldly, all-black, geometric structure built to provide cozy refuge even in harsh Finnish winters. It was designed for a California-based CEO who returned home to Finland with her family to be closer to her ancestral land so she could maintain it. The cabin is aptly named Meteorite based on its unique shape and is set in a clearing surrounded by spruce and birch trees. The cabin is made entirely from cross-laminated timber (CLT) which is a sustainable alternative to other construction materials.
