Out of the string theory swampland
Wednesday, 11 June 2025 06:37
String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of energy. But in the early 21st century, it was realized that most of the versions of reality described by string theory's equations cannot match up with observations of our own universe.

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet.
However, as published in Nature Astronomy, an international team of astronomers have found the unmistakable signature of a giant planet, called TOI-6894b, orbiting th Where did cosmic rays come from? MSU astrophysicists are closer to finding out

Star and planet formation has largely been considered separate, sequential processes. But in a new study, scientists at Southwest Research Institute (SwRI) have modeled a different scenario where planets start developing early - during the final stages of stellar formation - rather than after this phase ends, as previously assumed.
