The Science of the Final Threshold

A neuroscientist's personal reckoning with death and the limits of science—this is a daring exploration of consciousness that begins where traditional knowledge ends

What happens when a scientist experiences something his own discipline can’t explain? Is death the end of our existence? Or just the beginning of a deeper mystery science has yet to understand?

In The Science of the Final Threshold, theoretical physicist and neuroscientist Álex Gómez-Marín takes readers on a riveting exploration of the outer edges of consciousness, blending rigorous scientific inquiry with personal experience. After surviving a near-death experience in 2021, Gómez-Marín began rethinking everything he thought he knew about the mind, the brain, and what lies beyond.

Far from offering easy answers or spiritual platitudes, this book explores the cracks in modern neuroscience where mystery, meaning, and subjective experience push against the limits of the measurable. Gómez-Marín draws on decades of scientific training to engage with topics often dismissed by mainstream academia: out-of-body experiences, synchronicities, altered states of consciousness. Not to mystify, but to ask better questions.

A thoughtful, radical exploration of the mind’s unknowns. The Science of the Final Threshold invites readers to reconsider the foundations of modern knowledge, and to imagine a science brave enough to face what it still doesn’t understand.

This book doesn’t ask what we know. It delves deep into what we’re still afraid to question: about consciousness, death, and the limits of the scientific mind.
