SUMMARY
Planck curvature refers to the radius of curvature of the universe when it is in a quantum state, as discussed in Starobinsky's paper on the spectrum of relict gravitational radiation. This concept is crucial for understanding the transition from a quantum state to classical expansion in cosmology. The term is often confused with "plank curvature," which relates to the physical bending of materials, but in this context, it specifically pertains to the curvature at the Planck scale, approximately 10^-35 meters. The significance of Planck curvature lies in its implications for the early universe's dynamics and the nature of gravitational radiation.
