Ultra-faint dwarf galaxies, among the tiniest and faintest galaxies known, may hold the key to understanding one of the Universe’s biggest mysteries: the true nature of dark matter. A new study reveals that even a single collision between dark matter particles every 10 billion years — roughly the age of the Universe — is enough to explain the dark matter cores observed in these small systems. These galaxies, which contain only a few thousand stars, are dominated by dark matter and have relatively simple evolutionary histories. That makes them ideal cosmic laboratories for testing theoriesAdvertised on -
