Tethered: You are not alone

Tethered

How Science, Love, and Consciousness Reveal We Are Never Truly Alone

What if our deepest connections weren't just emotional - but physical, mental, even cosmic?

In Tethered, architect and philosopher Luís Portas de Ibérico Nogueira explores one of the most profound ideas of our time: that human consciousness is not a solitary spark, but part of a larger web of invisible threads - linking us to one another, to the universe, and to something far greater.

Drawing from physics, neuroscience, Eastern philosophy, personal story, and his original Tethered Consciousness Theory (TCT), Nogueira weaves a narrative that's both poetic and grounded in emerging science. From the Big Bang to brain-to-brain technology, from ancient mystics to modern love stories, he shows how every human relationship - every glance, every grief, every act of compassion - is a manifestation of something real: a tether.

Accessible, elegant, and bold, Tethered is a deeply hopeful meditation on what it means to be human in a fragmented world. Whether you're a seeker, a scientist, or someone who's simply felt the quiet truth that we belong to each other, this book will leave you seeing life - and connection - in a whole new light.
