freely? no, and it’s not a guess.
so are they limited ? yes
are they limited from the “same space we are” ? possibly not, depending of what do you consider “our space”
Anoikis, for instance, is another cluster altogether from the one of new eden.
we always get back to the basics: nothing is lost, nothing is created.
Wherever the collective come from, they need “fuel” to get from point A to point B.
As far as science is concerned, nothing lead us to the possibility of a physic mechanic implying transportation of complex entities on long distances.
that said, I’ll never be cautious enough: don’t take my words for the truth. it’s only hypothesis, yes, so far they hold the facts, but that the thing with scientific hypothesis
you only need one thing not fitting, and your hypothesis must be reworked.
EDIT::
we don’t have to “guess”, we already know the answer, it was the Chief of Deep Space Research of CONCORD, Professor Michel Mayor, to first report to the inner circle some anomalies
Late last year, Professor Mayor of CONCORD’s Project Discovery reported a series of unusual energy spikes to CONCORD’s Inner Circle.Follow up work mapped these energy spikes to POCKETS of space-time, similar to the spatial anomalies we call ‘Deadspace’, though these are more isolated and require special technology to access.
These hidden pockets have been code named 'Abyssal Deadspace‘.
As you know, a vessel of unknown origin and design was recently recovered by CONCORD forces. After transfer of this asset to the DED station in Yulai, CONCORD discovered a novel technology that allows entry to Abyssal Deadspace. Using this technology, we have successfully managed to send a solitary cruiser into the Abyss - to explore this new unknown.
and everything after that seemed to validate this hypothesis: the collective come from new eden’s cluster.
