Cosmic Birefringence: Astronomers Found A Big New Problem For Our Current Models Of Physics - IFLScience

NASA’s FY 2027 budget proposal slashes the agency by 23% and NASA Science by 47%, threatening Artemis II, the Roman Space Telescope, and asteroid defense. The Planetary Society condemns the cuts as out of step with bipartisan congressional and public support for space exploration.

Fossils unearthed in China reveal complex, three-dimensional animals thriving 539 million years ago—millions of years earlier than thought. The discovery challenges long-held theories about the Ediacaran period and the rise of modern animal life.

Physicists at the University of Waterloo and Perimeter Institute propose a radical new quantum gravity theory that eliminates the need for inflation to explain the Big Bang. Their quadratic gravity model suggests cosmic expansion arose naturally from quantum effects, offering testable predictions fo
