New data show that dark energy twice briefly became unstable, but a model with dark matter explains it all.

Dark energy twice crossed the forbidden line, showing its fickle nature. New data from DESI: the phantom divide was crossed, but without catastrophe. The model links this to dark matter: their interaction gives birth to ultra-light particles that could be the key to the puzzle.

🎯 Dark energy behaves like water that momentarily boils without forming bubbles — pressure spikes, but the system quickly settles down.

🎬 The idea of unstable dark energy spawned many stories about the 'Big Rip,' such as in Paul McAuley's novel 'The War with the Remotes'.

w = -1
w — a number that describes dark energy; if w < -1, the Universe expands with ever-increasing force, potentially leading to a rip.
