Apparently Something From Nothing

Metaphor 1: Fizz

The quantum foam. What we perceive as empty space is, at tiny scales, particles constantly emerge from and annihilate back into the vacuum "space"; governed totally by quantum uncertainty. This "fizz" is the baseline, the reality of our universe—not nothing, but not something.

Metaphor 2: Bank

Heisenberg's Uncertainty Principle allows for transaction: energy can be "borrowed" from the vacuum to create a particle, as long as it's paid back quickly. A cosmic bank loan. The larger the energy loan (creating a more massive particle), the shorter the repayment period (the particle's lifetime). Press the button to witness one of these fleeting transactions.

Repayment Time (Lifetime): ---

Metaphor 3: Dot

How did the structures of the universe, like galaxies, originate? Cosmic inflation says that in the first fraction of a second, the universe expanded exponentially. This stretched microscopic quantum fluctuations from the "fizz" into macroscopic seeds of varying density. The slightly denser regions, born from a random quantum event, became the gravitational anchors for the cosmic web we observe today.
