Cosmologist Proposes Framework for Laws of Physics Changing Over Time
João Magueijo outlines a model in which the fundamental constants and equations of physics evolved from an initial chaotic state before reaching their current form. The proposal addresses how physical laws could have originated without invoking deeper meta-laws.

Paper Recovers String Theory Amplitudes From Four Assumptions Using Bootstrapping
Theoretical physicists applied a bootstrapping technique to scattering amplitudes and arrived at the Veneziano and Virasoro-Shapiro amplitudes predicted by string theory. The paper by Clifford Cheung and colleagues was accepted to Physical Review Letters.

Physicists Use Particle Physics Link to Study Hawking Radiation
Researchers have applied a mathematical connection known as the double copy to translate Hawking radiation from general relativity into the language of the standard model of particle physics. The approach equates the radiation to a charged particle scattering off a collapsing sph…
