Anti-light

Anti-light
An exotic substance with bizarre properties which when exposed to photonic energy annihilates said energy with a force similar to an anti-matter explosion, but which is directly converted to angular momentum rather than destructive energy. This substance, exposed to different wavelengths of high-intensity photonics can produce both hyperoptic propulsion and when manipulated correctly, can be formed into an anti-photonic shell, cocooning a vessel within in a pocket universe, where said vessel will not accumulate mass, preventing time-dilation and relatavistic barriers to exceeding C.
