What is Quantum Inflation?
Quantum Inflation is a movement. A movement of people who believe that the universe is made of infinite layers of wobbly Jell-O. It's like that one aunt who just can't stop talking about herself, but instead of being annoying, it's cosmically fascinating.
According to our esteemed leader, Professor Pocket, Quantum Inflation is the result of a catastrophic event that occurred in 2008, where a rogue particle got too close to the space-time continuum and caused everything to get a little... puffy.
