Quantum Teleportation

This technology has been harnessed by the Humans, however it only works safely at a range of about 150m on a biological subject. Teleporting beyond this, or teleporting repeatedly, would result in cellular damage exponentially worsened by each subsequent jump or distance beyond the safety threshold. This can be bypassed, however, by suspending the subject in cryogenic ferrofluid. This is the basis of Lightspeed Travel.
