Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity In a triumph of observation and data processing, astronomers at the Event Horizon Telescope have captured the first-ever picture of the supermassive black hole at the center of the Milky Way Galaxy. The black hole is named Sagittarius A* (pronounced “A-star”), and the reveal of its image received anContinue reading “Heart of Darkness…”
Topics: Black Holes, Cosmology, Einstein, General Relativity When galaxies collide, the central supermassive black holes that they contain begin to orbit each other. This supermassive black hole binary attracts gas, which flows through the system to form two disk-shaped structures, one around each of the supermassive black holes. The gas in these “minidisks” heats asContinue reading “Shadow of Infinity…”
Topics: Civics, Civil Rights, Civilization, Existentialism, Fascism, Human Rights Vladimir Putin is a reality daytrader. His invasion of Ukraine is a “special military operation,” not a war, or more accurately, an ongoing war crime. Gaslighting eleven Russian time zones is as easy to him as flatulence. With the GRU and American social media, he canContinue reading “Reality Daytraders…”
Topics: Civics, Civil Rights, Cybersecurity, Existentialism, Fascism Summary This joint Cybersecurity Advisory (CSA)—coauthored by the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Energy (DOE)—provides information on multiple intrusion campaigns conducted by state-sponsored Russian cyber actors from 2011 to 2018 and targeted the U.S. and international EnergyContinue reading “Shields Up…”
Topics: Carbon Nanotubes, Materials Science, Nanotechnology From TNT to nitro-glycerine, nitrogen-rich compounds are known for packing an explosive punch. When these materials explode, bonds between atoms in the compounds are broken, which gives a chance for two nitrogen atoms to form very strong triple bonds with each other. This releases an enormous amount of chemicalContinue reading “Nanotubes and Nitro…”
Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity Each second, a brand new baby black hole is born somewhere in the cosmos as a massive star collapses under its own weight. But black holes themselves are invisible. Historically, astronomers have only been able to detect these stellar-mass black holes when they are acting on aContinue reading “Rogue Singularity…”
Topics: Astronautics, Climate Change, Environment, Futurism, Global Warming, Mars, Spaceflight When Elon Musk founded SpaceX in 2002, he envisioned a greenhouse on Mars, not unlike the one later depicted in the 2015 blockbuster The Martian. Soon, his fantasy grew from a small-scale botanical experiment into a vision for a self-sustaining Martian city. In a speech at theContinue reading “Caveat Colonizing…”
Topics: Fermilab, High Energy Physics, Modern Physics, Particle Physics, Steven Weinberg The most precise measurement to date of the mass of the W boson has yielded a result seven standard deviations away from that predicted by the Standard Model of particle physics. The stunning result was obtained by a painstaking analysis of data taken atContinue reading “Weighty W…”
Topics: Civics, Civil Rights, Democracy, Fascism, Politics In Roman mythology, Janus was the god of doors, gates, and transitions. Janus represented the middle ground between both concrete and abstract dualities such as life/death, beginning/end, youth/adulthood, rural/urban, war/peace, and barbarism/civilization. Source: Anderson Lock Blog (they’re apparently locksmiths and historians on the side) Vladimir Putin’s war of aggressionContinue reading “Leverage and Looting…”
Topics: Condensed Matter Physics, Superconductor, Thermodynamics Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures ofContinue reading “Fourth Signature…”
