Drakador_Chaos Neither - it makes a controlled, sizable tear in the fabric of space-time between two target dimensions so that large fleets can travel almost instantaneously between those said dimensions. Though there has to be specialized "Rift stabilization" ships on both openings in the tear to stabilize/repair damage to the forces of the universe for such a powerful fracture. They even have failsafes - if one end no longer has any rift stabilization ships, the other end immediately tries to close the rift. Damage only becomes lasting if one end gets destroyed and the other end malfunctions, then there is a serious problem with the space-time continuum.
Alpha-Alpha is very much aware of the laws of the universe and has used these techniques in the past against other races, mainly on enemies living in the 4th dimension (the Dimensional Collective lives in the 6th, which in my head is the realm of thought (scientifically inaccurate, but at least to me it makes sense)). The only way I can see the Judges interfering is if they forbid weaponizing the flow of time and space in such manners.
I could go into more detail than this, but I would like to avoid walls of text.
