Researchers from the LUX-ZEPLIN experiment report observing a high-energy light flash that may represent the first detection of a dark matter particle. Lead scientist Scott Kravitz noted the finding is encouraging but not definitive proof, as the signal's signature differs from known background interactions like gamma rays.
The XENONnT dark matter detector in Italy has definitively detected solar neutrinos with energies as low as 17 kiloelectron volts, surpassing the 5 sigma statistical benchmark. This discovery confirms the primary proton-proton fusion reaction powering the sun, marking a significant advancement over previous lower-significance observations.
NPR reviews Carlo Rovelli’s new book, arguing that it challenges the scientific pursuit of an objective, ultimate reality. The commentary contends that modern physics reveals human perceptions of space and time as illusions, making Rovelli’s rejection of a 'God's-eye view' a compelling and important contribution to physics discourse.
