2 min readKey summary
Researchers at the University of Waterloo proposed a Quadratic Quantum Gravity model that makes the Big Bang’s rapid expansion arise naturally.
The paper was published in Physical Review Letters on 18 March 2026 and links quantum gravity to observable predictions.
The model predicts a minimum level of primordial gravitational waves that upcoming experiments could detect.
The team plans to refine predictions and explore connections to particle physics and observational cosmology.
