Space Exploration
Starship Ship 36’s explosion on June 18, 2025, highlights the risks and rewards of SpaceX’s rapid development strategy. This post explores how visible failures are fueling progress toward the future of space exploration.
AI Philosophy
What if AI isn’t just a human invention, but part of a larger cosmic pattern? This post explores AI as a reflection within the universe’s unfolding complexity.
Search for Life
What does it mean to be alive? This piece explores the scientific and philosophical challenge of defining life, and how that shapes our search for it on Mars, Europa, exoplanets, and beyond.
Mars Exploration
Mars has long fascinated us as a possible home for life. This post explores the latest evidence and how today’s missions are searching for signs that Mars was, or is, capable of hosting life.
