LIGO has detected GW250114, the loudest gravitational-wave signal yet, marking ten years since its first breakthrough. The event confirmed Einstein’s relativity, Hawking’s horizon theorem, and Kerr’s spinning black hole model. By capturing the merger of two 32-solar-mass black holes, scientists gained the clearest view of black hole physics, offering new insight…

NASA has certified a helicopter-based lander training course in Colorado’s Rocky Mountains to prepare Artemis astronauts for Moon missions. The high-altitude terrain creates lunar-like visual illusions, forcing pilots to master landings in dusty, slope-filled conditions. Over two dozen astronauts have now trained in this challenging, realistic simulation.
