Researchers are seeking cheaper approaches to creating a technology described by Scotty in “Star Trek IV.” And physicists explored the creation of a singularity-free black hole through pure gravity. Additionally, although I don’t want to swamp you with physics news, some theoreticians found evidence of two arrows of time in the quantum realm. And the complexity of birds’ brains evolved independently from mammals.
