The John Chappell Natural Philosophy Society (CNPS) is a vibrant community dedicated to the exploration and debate of unconventional scientific ideas, theories, and philosophies that challenge mainstream science. Founded in 2014 by active members of the Natural Philosophy Alliance, this organization embraces a broad interpretation of "Natural Philosophy," encompassing fields such as physics, cosmology, mathematics, and the philosophy of science. With a mission to foster critical thinking, CNPS provides a welcoming forum for individuals—ranging from academic professionals to curious laypeople—to discuss pressing topics and present serious research without fear of censorship.

Inspired by the legacy of Dr. John Chappell, a pioneer in dissident science, the CNPS encourages a collaborative environment where innovative concepts can flourish. Through online meetings, blogs, and community involvement, CNPS aims to inspire a return to fundamental scientific principles and redefine our understanding of the universe. Members actively engage in shaping the society's direction, ensuring a truly democratic organization committed to the pursuit of truth in science.
