The cosmos is expanding faster than predicted. Scientists have proposed that in the universe’s infancy, something like a switch flicked—a sudden phase transition in the invisible dark sector. It gave expansion a boost and reconciled the star-based maps with the cosmic microwave background.
🎯 Phase transitions aren’t fiction: it’s believed that in the first second after the Big Bang, the universe underwent several such transformations, giving rise to the forces of nature we know.
🎬 In Isaac Asimov’s novel 'The Gods Themselves,' contact with a parallel universe where the laws of physics are different—isn’t that a dark sector with its own hidden rules?
