[@ZAVAZggg] Everyone even this far off in the future will be giving off some form of heat signatures people with tech like ours will most likely detect.  

With the huge spans of time there is good chance prior interactions have occurred, like it's why I am certain the administrators had some historical troubles with my civ.

I don't think a blitzverzerrung would typically give off a heat signature, based on its design and the fact it exists outside of "normal" spacetime, but you'd see localized gravitational waves as the warp bubble moves around. And definitely a heat/energy signature when it does its scan.
