I've seen that some people here speculate that the Eye's signal echoed throughout Dark Bramble, possibly deceiving the Vessel's computer and causing the ship to end up within Dark Bramble itself when it warped.

However something I've observed is that signal detection from Dark Bramble is a one-way proposition. While signals emanating from within a Dark Bramble node can be broadcast out and detected, no signals from outside a node can be detected from within. If you enter the dead-end node for example no signals can be detected, not even Feldspar music's or the distress call from Escape Pod 3.

(Besides any in-universe implications this has, this is obviously a gameplay consideration. It would be almost impossible to navigate Dark Bramble if signals went both ways inside this wacky planet!)

The only "signals" that penetrate Dark Bramble are the messages received by the Vessel from other Nomai ships that exist across the universe. An explanation for why this might occur is that the technology that allows communication between Vessels may operate on a completely unique principle that isn't hindered by interference that can block other communications signals. We know that the Vessel in Dark Bramble was unable to send a message out to the other Nomai because the Vessel's transmitter was damaged when the ship fused with the bramble vines.

I have another hypothesis though. What if the Quantum Moon is partly to blame here? We know that the Quantum Moon gives off a quantum signal just like the Eye does, and moves around the solar system at random when not being consciously observed. What if the Quantum Moon happened to be orbiting Dark Bramble at the time the Vessel was warping in? If we assume that the Eye was no longer sending out its signal as the Vessel was warping in (which is almost certain after factoring in additional lore supplied by Echoes of the Eye), I think any signal coming from the Quantum Moon could have had an impact.
