Universe to End in Big Crunch in 33 Billion Years? | JQJO

A new study predicts the universe will end in a "Big Crunch" in approximately 33.3 billion years. Researchers, using data from various astronomical surveys, propose a model suggesting dark energy is dynamic, not a constant. This model involves an ultra-light particle and a negative cosmological constant, causing the universe to eventually contract after reaching maximum expansion in about 7 billion years. While the prediction has significant uncertainty and alternative scenarios exist, upcoming astronomical projects could test and potentially confirm or refute this theory.
