Revolutionary Model Reveals How Real Universe Structure Affects Cosmic Evolution

Universe Today - Tue, 09/02/2025 - 3:58am

For nearly a century, cosmologists have relied on a simplified model of the universe that treats matter as uniform particles that don't interact with each other. While this approach helped scientists understand the Big Bang and the expansion of space, it ignores a fundamental reality, that our universe is anything but uniform. Stars cluster into galaxies, matter collapses into black holes, and vast empty voids stretch across space, all constantly interacting through gravity and other forces.

White Dwarf Stars Could Create Surprisingly Common Long Lived Habitable Zones

Universe Today - Tue, 09/02/2025 - 3:58am

When most stars like the Sun die, they don't go out with a bang, they fade away as white dwarf stars, Earth-sized remnants that slowly cool over billions of years. For decades, it was thought these stellar corpses were poor candidates for hosting life because they cool predictably, giving any orbiting planets only brief windows in the "habitable zone" where liquid water could exist. But new research suggests this assumption may be fundamentally wrong.
