Dark energy, which makes the universe expand faster and faster, may not be constant. New data from the DESI telescope hint that around 6 billion years ago, it changed its behavior, crossing a phantom divide. A simple model with a barely noticeable friction explains this shift without exotic inventions — as if a pendulum were gradually slowing down.
🎯 The density of dark energy is so tiny that within the volume of Earth, it would amount to just a couple of kilograms — yet on cosmic scales, it determines the fate of the universe.
