Revolutionary Lunar Origin Theory Challenges Decades-Old Planetary Science Models Long-Standing Mystery: How the Moon Really Formed One of the longest-standing mysteries in planetary science is how the Moon came into being. More than a century ago, George Darwin suggested that powerful tidal and centrifugal forces acting on a rapidly spinning proto-Earth caused the Moon to break away and settle into orbit around the planet. However, the idea later conflicted with the laws of conservation. A proto-Earth rotating with a day lasting just two to three hours would have possessed roughly four times the angular momentum of the present Earth-Moon system, raising the question of where that excess momentum went. Theia Impact: The Dominant Modern Hypothesis The leading explanation that emerged instead proposes that a Mars-sized object, dubbed Theia, collided with the proto-Earth. The impact ejected material from both bodies into orbit, where it eventually clumped together to form the Moon. When ...

How Dark Matter Could Shape the Fate of Exploding Stars—New Study Reveals Hidden Forces Behind Electron-Capture Supernovae The Rare Stellar Explosions That Birth the Lightest Neutron Stars Electron-capture supernovae (ECSNe) are among the universe's most mysterious and least understood explosions. These events occur when stars, initially weighing about eight to ten times the mass of our Sun , develop unstable oxygen-neon-magnesium (O-Ne-Mg) cores. When electron inside the star's core are captured by neon and magnesium nuclei , internal pressure suddenly drops. The core collapses under its own gravity, triggering a supernova explosion and forming a neutron star — a city-sized object composed almost entirely of neutrons. Recent observations, such as Supernova 2018zd (SN2018zd) , have confirmed that these rare events truly exist, providing vital clues about stellar evolution and the delicate balance between gravity and nuclear forces. For deeper insights into the origins of neut...
