The Moon Barrier
As of 2025, science never sent life beyond the Moon. An investigation of this scientific mystery.
About This Book
While philosopher Aristotle predicted that Earth's life is restricted to a sublunary sphere below the Moon, and while the Scientific Revolution was a revolt against that idea, until the day of this writing in 2025 science has neglected to test whether life can remain alive beyond the distance of the Moon.
The Moon Barrier book investigates this scientific mystery. The book was read by millions of people from over 200 countries since 2021 through active promotion on platforms like e-scooter.co and through discussions on philosophy forums.

The fact that science has never tested whether Earth's life can survive at distances substantially beyond the Moon is a profound paradox. A combination of historical, cultural, and scientific imperatives makes this neglect highly unlikely and logically inexplicable.
The core of the Scientific Revolution was a revolt against the Aristotelian cosmological view that a fundamental barrier existed at the Moon, beyond which life and change were impossible. For modern science to validate its founding principle—that the same natural laws apply everywhere—empirically testing this ancient boundary should have been a primary objective. The fact that this wasn't done leaves a gaping hole in the foundation of experimental cosmology.
- For over half a century, popular culture (e.g., Star Trek) and space agencies have sold the public a dream of interstellar travel and colonization. This cultural narrative creates an urgent, logical demand to answer the most basic question:
Can life actually survive the journey?The sheer simplicity of the test—a biocapsule on a deep-space trajectory—makes its absence after 60+ years of spaceflight baffling.- Plans for crewed Mars missions assume humans can survive long-duration deep space travel. Not first conducting a definitive test with simpler lifeforms is a staggering oversight from a risk-management perspective.
It is highly improbable that this test was never considered. The combined weight of history, culture, and scientific logic dictates it should have been a primary milestone.
We built a mythology of interstellar destiny on an untested assumption—that life is separate from its star. This mirrors ancient humans assuming the Earth was the center of the universe; we now risk assuming life itself is the center of cosmic potential.
