If an asteroid that size hit Earth today, a shock wave two million times more powerful than a hydrogen bomb would flatten forests and trigger tsunamis. A seismic pulse equal to a magnitude 10 earthquake would crumble cities.
And long after the impact, a cloud of hot dust, ash, and steam would blot out the sun, plunging the Earth into freezing cold.
New plasma stealth device targets specific areas, not entire aircraft.
Chinese scientists develop plasma stealth device, hiding military aircraft from radar, focusing on shielding specific areas, potentially changing stealth technology.
In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of “Single Energy Interval Value (SEIV)” and “Energy Spectrum Total Value (ESTV)”, which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.
The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.
J. Robert Oppenheimer’s grandson is among the star-studded signatories of a new open letter about the dangers artificial intelligence poses to the planet.
Charles Oppenheimer, who founded the Oppenheimer Project to continue his grandfather’s mission of tempering scientific progress with “international cooperation and unity,” was joined by hundreds of others, including British billionaire Richard Branson, AI pioneer Geoffrey Hinton, writer and Carl Sagan widow Ann Druyan, and musician Peter Gabriel. In it, they warn that the world “is in grave danger” as we face down the perils of AI.
Text-to-video has become the latest arms race in generative AI as OpenAI, Google, Microsoft and more look beyond text and image generation and seek to cement their position in a sector projected to reach $1.3 trillion in revenue by 2032 — and to win over consumers who’ve been intrigued by generative AI since ChatGPT arrived a little more than a year ago.
Ultimate fact presents top 15 Weapons Of The Future Will Blow Your Mind. We’ve come a long way since sticks and stones, and it’s almost inconceivable that only a few hundred years ago, Man was still waging war with bows, arrows, cannons, and muskets. Modern militaries are constantly in the process of developing new weapons, some of which will definitely make some mouths drop. We thought it would be fun to take a closer look at the most amazing offensive and defensive weapons currently in the works. Autonomous weapons. These are robotic vehicles, under development, that search and destroy enemy troops and equipment on the ground or in the air, without risk to friendly troops – theoretically. Onboard computers interpret sensor data to identify and target hostile forces with built-in weapons. Robots may query human controllers at remote sites for the go-ahead to fire, and friendly forces may carry transponders that identify them as “friends” High-energy lasers. These are powerful energy beams that travel through air or space in straight lines. They travel at the speed of light and can strike over distances of thousands of kilometres. Large mirrors focus powerful laser beams onto a small spot on the target. Space-based weapons. Space is the ultimate high ground, so weapons in orbit would have the ability to see and zap anything on the ground, in the air, or nearby in space. The main mission of space-based weapons would be to defend against ballistic missiles fired at targets on Earth. Hypersonic aircraft. Launched from a standard runway, a hypersonic aircraft could fly faster than Mach 5 to strike anywhere in the world within two hours. It would also have enough thrust to deliver a satellite to low-Earth orbit. To get off the ground from a runway, a hypersonic plane would either hitch a ride on a conventional plane, or have its own conventional jet engine. Active Denial System. Millimetre-wave or microwave beams supposedly make people flee without injuring them. They might typically be powered by a generator fitted to a Humvee, in crowd control situations. A 2-metre antenna and mobile generator produce and aim a beam of 95-gigahertz (3-millimetre) radiation. Nuclear missiles. Nuclear missiles are able to deliver unmatched destructive power anywhere in the world, making them the ultimate level of military power. One or more nuclear warheads are mounted on a ballistic missile, and launched vertically. Stun guns (Tasers) Tasers disable people with bursts of high-voltage electricity, allowing police to subdue them without lasting injury. A special gun fires darts on wires. These deliver a pulse of electricity that temporarily disrupts control of voluntary muscles. E-bombs. A rapid increase in electromagnetic field strength during a pulse, induces surges of electric current in conductors. This burns out electrical equipment – semiconductor chips are particularly vulnerable. Layered missile defence. Layered missile defence offers the best chance to shoot down attacking ballistic missiles. Multiple anti-missile systems are deployed to target ballistic missiles during different stages of the attacking missile’s flight: Each phase, or layer, of defence increases the chance of successful destruction of the missile. Information warfare. This technique interferes with the flow of information vital to enemy operations, while defending friendly channels of communication. Information warfare specifically targets communication networks and computers. ‘Hyper Stealth’ or ‘Quantum Stealth’ Using naturally occurring metamaterials, scientists have been designing lightwave-bending materials that can greatly reduce the thermal and visible signatures of a target. Electromagnetic Rail Guns. EM rail gun launchers use a magnetic field rather than chemical propellants (e.g., gunpowder or fuel) to thrust a projectile at long range and at velocities of 4,500 mph to 5,600 mph. nautical miles using 32 megajoules. The extended velocity and range of EM rail guns provides several benefits both in offensive and defensive terms, from precision strikes that can counter even the most advanced area defense systems to air defense against incoming targets. Space Weapons. Despite international pressure against the weaponization of space, major countries continue to explore technologies that would turn the sky above us into the next battleground. Hypersonic Cruise Missiles and ‘Prompt Global Strike’ Had hypersonic cruise missiles existed in the mid-1990s, the U.S. might have rid itself of Al Qaeda leader Osama bin Laden much earlier than it did, and would have accomplished the feat in Afghanistan rather than in Pakistan. Sentient’ Unmanned Vehicles. Perhaps the single-most important development in the defense industry in the past decade is the emergence of unmanned vehicles. Among this which one seems most terrible to you let us know in the comment section. #UltimateFact #Weaon #Facts
WASHINGTON — Lockheed Martin is experiencing a growth spurt in an unexpected corner of its business: small satellites. While traditionally known for its expertise in GPS and giant geostationary (GEO) satellites, the company has quietly built a backlog of 100 smallsats on order from Department of Defense and intelligence customers.
“This is probably a different picture than many of you may have in our minds” about what the company does, Johnathon Caldwell, head of Lockheed Martin’s military space business, told a military conference Feb. 14.
Speaking at the Air & Space Forces Association’s Warfare Conference in Aurora, Colorado, Caldwell said a greater focus on small satellites began with the company’s pursuit of Space Development Agency contracts. SDA is building a proliferated mesh network of satellites in low Earth orbit for the Defense Department, and unlike traditional cost-plus defense programs, the agency demands fixed-price bids from satellite manufacturers.
WASHINGTON — Viasat announced it completed the first satellite broadband upgrade on board a Military Sealift Command ship, and expects to update 105 vessels over the next year. The work is part of a $578 million contract that Inmarsat won in 2022 before it was acquired by rival satellite operator Viasat.
The U.S. Navy’s sealift organization, responsible for providing ocean transportation to the Department of Defense, operates a fleet of approximately 125 civilian-crewed ships that replenish Navy vessels at sea, transporting military equipment and personnel, and strategically positioning cargo around the world.
Viasat is revamping the ships’ satellite network from Ku-band to the company’s Global Xpress Ka-band and the ELERA L-band systems.
