Out of the string theory swampland

Researchers propose a new subset of string theories that incorporate dynamic tension could help describe the real universe without violating observational constraints. This approach may alleviate the 'swampland problem,' which has hindered conventional string theory's ability to reproduce inflation and dark energy.

CDEX listens to the sound of cosmology from a laboratory deep underground

The China Dark matter Experiment (CDEX) has presented new limits for the couplings of weakly interacting massive particles (WIMPs) in the non-relativistic effective field theory approach, improving over current bounds in the low mass region. CDEX's analysis also extended the limit on WIMP-pion coupling to the mχ< 6 GeV/c2 region.

New machine learning theory raises questions about nature of science

A novel machine learning algorithm developed by Princeton physicist Hong Qin accurately predicts planetary orbits without using traditional physics laws. The technology has potential applications in predicting plasma behavior in fusion facilities, challenging the fundamental role of theories in science.

Paving the way for effective field theories
