Dark energy was not always repulsive. Perhaps in the past it acted as attraction. A new model with a phantom field shows a smooth transition without catastrophe, shedding light on discrepancies in measurements of the universe's expansion.
🎯 Phantom energy is so named for its ability to violate physical laws, like a ghost passing through walls.
