How the Universe is Born from Nothing ⚡ экспресс
Original: "Gaussian fluctuations in the tunneling probability of a closed universe"
Physicists have refined the probability that an entire universe can arise from nothing.

The universe can appear from nothing — literally. Quantum laws allow a tiny lump of emptiness to suddenly explode into a whole world, like a bubble in boiling water. The new work refines how often this happens, adding quantum ripples to the calculations.
🎯 In quantum physics, even a particle can pass through a wall. It turns out that mathematically, a whole universe is no different — it's the largest 'tunneling' object ever studied by scientists.
P \approx A \, e^{-S_E/\hbar}
P — probability of a universe being born; A — contribution from quantum fluctuations, described by a bell-shaped curve; S_E — a measure of how 'reluctantly' the void gives birth to a world (calculated using a mathematical trick treating time as a fourth dimension); ħ — Planck's constant.
