📍 Aftermath
A Cornell-led team presented a model that would halt cosmic expansion in about 11 billion years and lead to a Big Crunch roughly 20 billion years later, while researchers at Yonsei University suggested the universe may not be accelerating, prompting commentary that current models of expansion could be wrong. The coverage framed the issue as an ongoing crisis in cosmology with no definitive resolution reported.
