>>114752358I know the exact lore snippet you are referencing. It mentions exploration probes sent out 14,000 years ago that are still returning signals, and many if the signals are orkish. It never says the probes have left the milky way. The AdMech don't actually know where the probes are, and have no way of determining. All it means is that the AdMech don't know of anywhere within reach that isn't full of orks, not that there are not orks in other galaxies.
And while I know that GW is incredibly shit at real world science, even if the probes had FTL to get out there in the first place the signals coming back from them are still radio. A signal from another galaxy, even given 14,000 years, wouldn't even have reached us yet. The only FTL communication that the IoM has is psyker based, so the probes can't be using that to report back. They have to be sending radio waves.
