- Two independent teams have shown that gravitational waves emanating from the distorted remnants of black hole mergers should interact with themselves. The findings may finally prove stringent enough to push Einstein’s theory to its limits – which could allow new and exciting physics to emerge. https://physicsworld.com/a/gravitational-waves-from-merging-black-holes-go-nonlinear/ 60 comments science

- Galactic 'bridges' could be the largest rotating structures ever discovered. Astronomers have uncovered evidence that cosmic filaments – tendrils of matter that stretch across hundreds of millions of light years – are also spinning. Rotation on such gigantic scales has never been observed before. https://physicsworld.com/a/galactic-bridges-could-be-the-largest-rotating-structures-ever-discovered/ 172 comments space

- In 1974, Stephen Hawking theorized that black holes emit some kind of radiation. Now, nearly fifty years later, a group of researchers have finally managed to provide experimental evidence for Hawking radiation. https://physicsworld.com/a/physicists-stimulate-hawking-radiation-from-optical-analogue-of-a-black-hole/ 3 comments science

- Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. Physicists, who have devised a new cosmological model positing the existence of an “antiuniverse” which, paired to our own, preserves a fundamental rule of physics called CPT symmetry. https://physicsworld.com/a/our-universe-has-antimatter-partner-on-the-other-side-of-the-big-bang-say-physicists/ 1296 comments space
