The universe consists of a massive imbalance between matter and antimatter. Antimatter and matter are actually the same, but have opposite charges, but there's hardly any antimatter in the observable universe, including the ...

(Phys.org)—It was an intriguing week for physics as a pair of theorists suggested that their quantum equation predicts the universe has no beginning and thus there was no Big Bang. In their paper published in Physics Letters ...
The James Webb Space Telescope has discovered what appears to be a new record-holder for the most distant known galaxy, a remarkably bright star system that existed just 290 million years after the Big Bang, NASA said Thursday.

(PhysOrg.com) -- Back in 2006, PAMELA (a Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) was launched with the purpose of detecting cosmic radiation and looking for clues pointing to dark matter. ...
(Phys.org)—Physicists have discovered a surprising consequence of a widely supported model of the early universe: according to the model, tiny cosmological perturbations produced shocks in the radiation fluid just a fraction ...
They announced the Nobel prizes this week! But did any of the recipients teach an AI to play Street Fighter? Here are a few of this week's stories not yet lauded by international committees of scientists, but which we thought ...
A team of astronomers led by Caltech has discovered a giant swirling disk of gas 10 billion light-years away—a galaxy-in-the-making that is actively being fed cool primordial gas tracing back to the Big Bang. Using the ...
