·1 views

Scientists have used a small reflective orbiting satellite, often likened to a disco ball, to conduct the most precise test of Einstein's general theory of relativity to date. The experiment measured how Earth's mass warps the fabric of space-time, a phenomenon predicted by Einstein's theory. Despite Earth being relatively modest in mass compared to other celestial bodies, its gravitational influence was still measurable with high accuracy. The findings represent a significant milestone in validating one of the foundational theories of modern physics.

ICE Threatens to Deport Witnesses After Fatal Houston Shooting of Mexican Immigrant

ICE officers fatally shot Lorenzo Salgado Araujo, a Mexican immigrant, during a traffic stop in Houston earlier this week. Advocates are calling on the Department of Homeland Security to release bodycam footage of the incident. DHS says the agents involved were not equipped with body cameras, citing a 76-day government shutdown that cut federal funding for ICE and CBP equipment. The shutdown itself was triggered by congressional disputes over DHS reforms following the killing of two civilians by federal agents earlier this year. Witnesses to the shooting are now reportedly facing deportation threats from ICE.
