Neural physics was a Precursor concept. The Precursors felt that the Mantle extended to the entire universe, including energy and matter. The principles of neural physics also postulated that the entire universe was living, but in a way that was beyond the comprehension of biological organisms.[1]

Precursor technology was based upon the principles of neural physics. While this normally made most Precursor artifacts effectively indestructible, the nature of their construction made them extremely susceptible to the effects of the Halo Array which specifically targeted neural systems. When a Halo was tested near Charum Hakkor, the weapon's effect negated neural physics within the region and shattered every Precursor structure on the planet.
