In the first moments, the Universe was squeezed to tiny sizes. What keeps it from collapsing entirely into a point? One answer comes from quantum mechanics: the wave function describes all possible states, and particles move along hidden trajectories that depend on the shape of this wave.

Immediately after the Big Bang, the Universe underwent ultra-fast expansion, an idea proposed by Alan Guth and developed by Andrei Linde. When the expansion stopped, the field-energy began to oscillate like a giant swing.

In physics, there's an old ache. General relativity paints the beginning of the universe as a point — a singularity where equations break down and volume shrinks to zero. Quantum mechanics hints that at the most critical moment, something goes differently than classical physics predicts.
