Slipspace field pod

Slipspace Field Pods are the Forerunner equivilent of the UNSC cyrotubes, aside from the fact that they are linked directly with slipspace.

Forerunner cyrotubes are somehow connected to slipspace and normal space, the actual bodies are within slipspace, making them safe from nearly everything. (Nearly means that they might be able to get killed if they are engaged within slipspace, otherwide, normal space can not hurt the person inside.) They are visible via an afterimage that is somehow also portable, but they are at the same time in slipspace. This can be compared to getting sucked into a black hole, in real life, or what scientists think would happen if that were to occur. The gravity of the black hole distorts time the closer you get, at a certain point, stopping time for you (althought singularity would problably kill you), and if another person was watching, they would see you frozen in time. You are visiblly there, but you are not, you are stuck in a vacum of time, which might be what causes those afterimages from the pods in Halo: Ghosts of Onyx.
