Unseen Spectrum: Electromagnetic Frequencies That Pass Through All Known Matter Undetected Theoretical Physics of the Truly Invisible

Some books explain what we know. This one follows the physics to the edge of what we cannot see.The electromagnetic spectrum stretches from radio waves longer than a continent to gamma rays smaller than an atomic nucleus. Physicists have mapped it, measured it, and built entire civilizations on its properties. Yet the deepest equations of theoretical physics quietly insist that this map is incompl...
