Quantum Bounce: How the Universe Became Uniform ⚡ экспресс
The universe might have been born crumpled and uneven, but quantum effects, like an invisible baker's rolling pin, roll it into a smooth, flat pancake. In a new model, cosmologists showed that after a 'bounce' (instead of the Big Bang), any spatial distortion quickly disappears on its own, without help. The universe itself becomes homogeneous and isotropic. Maybe that's how smooth worlds are born?
The early universe was far from perfect: some regions stretched faster than others, creating folds and warps. But a quantum bounce — the transition from contraction to expansion, driven by the laws of the microworld — fixes everything. Instead of a Big Bang with its crushing density, the universe first contracts, and then, due to quantum corrections to spacetime curvature, it rebounds and begins the expansion of the universe. At that moment, all irregularities vanish, like wrinkles in a sheet when you sharply tug on its corners.
Amazingly, this mechanism works for any composition of matter — whether particles, radiation, or something else. The outcome doesn’t depend on what the ‘sheet’ of the cosmos is made of.
🎯 During a quantum bounce, the fabric of space doesn’t collapse into a point of infinite density but smoothly unfurls, like a crumpled sheet after a swift tug.
