New Quantum Theory Predicts Detectable Gravitational Waves

3/31/2026

Summary

Story summary

Researchers from the University of Waterloo and the Perimeter Institute developed Quadratic Quantum Gravity to explain the Big Bang.
This framework extends beyond General Relativity to address limits under extreme conditions.
Dr. Niayesh Afshordi (University of Waterloo; Perimeter Institute) leads the team, showing cosmic inflation can arise naturally from this theory.
The framework predicts detectable primordial gravitational waves that could test the theory.
Findings were published in Physical Review Letters.
