New Theory Combines Early Cosmic Inflation and Quantum Gravity

Comparison of the quadratic gravity model and observations. Credit: Liu, et al.

Modern cosmology is built on three theoretical pillars: special relativity, Newtonian gravity, and quantum mechanics. Each is supported by considerable experimental evidence, but each describes the physical world in a way that contradicts the other two. Quantum theory describes a small. Objects that are driven by electromagnetic forces, both strong and weak. The dim world … Read more
