Model selection between the original BMS symmetries (dashed lines) and the extended BMS symmetries (solid lines) with Einstein Telescope (ET) and Cosmic Explorer (CE). Evidence for the simulated symmetry group (log Bayes factor) is shown against observation time. Credit: Physical assessment letters (2024).

Antarctica’s vast ice fields and the floating sea ice that surrounds the continent are Earth’s largest heat shields, reflecting solar radiation away from the planet. Two studies released today show how global warming is penetrating even the sunlight reflector in the coldest region on Earth. Research by scientists from the British Antarctic Survey focused on … Read more
