Hyperspace

Hyperdrive was a Niex concept, eventually passed on to the Forerunner. Although it's general discovery may be attributed heavily to neural physics, it's usage was eventually mastered by other means.

Although kept classified, the secret to performing hyperspace jumps were passed down through a galaxy's mantle keeping lineage. It is known, however, that hyperdrive places emphasis on the notion of perfected Slipspace utilizing extremely dense forms antimatter contained within electrically charged magnetic coils.
