K2-18b and the Quest for Extraterrestrial Life: Breaking Down the Dimethyl Sulfide Discovery
Floating in the habitable zone of a distant red dwarf star, K2-18b has become one of the most talked-about exoplanets in recent memory—and for good reason. The recent detection of dimethyl sulfide (DMS), a molecule typically produced by life on Earth, has ignited both excitement and caution among scientists. Could this be a sign of alien biology, or just chemistry playing tricks on us? As telescopes become our time machines and spectrometers our sniffers of distant worlds, K2-18b invites us to rethink what we mean by 'life'—and how we'll know it when we see it.
What Came Before the Big Bang? Exploring Six Theoretical Possibilities
What came before the Big Bang? Did time start at that moment, or is our universe part of something even grander? In this deep dive, we explore six cutting-edge theories—Big Bounce, eternal inflation, cyclic universes, quantum fluctuations, and more—highlighting state-of-the-art research, limitations, and what it would take to prove them. If an alternative to the Big Bang is confirmed, it could reshape our understanding of time, space, and existence itself. Read on to explore the frontier of cosmology!
