"Expansion of Our Universe Linked to Merging with 'Baby Universes', Theoretical Study Finds"

A new theoretical study suggests that our universe's accelerated expansion may be caused by merging with "baby" parallel universes, rather than by dark energy as currently theorized. The study proposes a mathematical model to explore the impact of these interactions, suggesting that the merging with other universes could explain the observed expansion more accurately than the traditional Standard Cosmological Model. This theory also addresses the problem of cosmological inflation, proposing that the early rapid expansion of the universe could have been caused by absorption into a larger universe. Observational data from ongoing experiments may help validate this hypothesis in the future.

"Unveiling the Timeless Influence of an Old Law on Quirky Quantum Materials"

A theoretical study by researchers at SLAC National Accelerator Laboratory, Stanford University, and the University of Illinois suggests that the 170-year-old Wiedemann-Franz law, which relates the ratio of electronic conductivity to thermal conductivity in metals, still approximately holds for copper oxide superconductors (cuprates), a type of quantum material. The researchers propose that other factors, such as vibrations in the material's atomic lattice, may account for experimental results that make it seem like the law does not apply. This finding is significant for understanding unconventional superconductors and other quantum materials.
