That night, he mounted the mirror in his basement rig. He switched on the laser. The beam hit the dielectric surface and bounced with such terrifying perfection that there was no "scatter"—no little dot on the glass to show where the light touched it. To the naked eye, the beam seemed to pass through a hole in reality and emerge elsewhere.

Unlike a standard silvered glass that reflects everything with a shrug, a dielectric mirror is a prima donna of physics. It’s built from thin layers of transparent materials that use constructive interference to reflect specific wavelengths with nearly 100% efficiency.

He found a boutique manufacturer online— Lumen & Lattice . Their catalog didn't just list prices; it listed "Purities." He clicked on a 2-inch substrate optimized for 532nm—the precise, piercing green of a laboratory laser. To the naked eye, the beam seemed to
