You were much more grandiose than me in going full quasar, and I give you credit for that. I had merely contemplated neutron star mergers and magnetars.
Now, however, you are back to tedious.
Evidence is a fact which makes a proposition more likely than would be the case in the absence of that fact.
You fall victim to the common error of equating “evidence” with “proof.”
Proof is an accumulation of evidence sufficient to establish a proposition beyond some applicable threshold, such as preponderance, clear and convincing, or beyond reasonable doubt.
It has been famously said that “evidence is not proof, just as a brick is not a wall.”
The fact that precursor civilizations spy on us makes the proposition that we are of some significance more likely than would be the case if they didn’t bother spying. Spying on us is therefore evidence of our significance. No, by itself it does not amount to proof.
It is always a mystery what statements will prove controversial.
Suggesting something called an “Observatory” might look across a variety of space-time topologies (to use the fancy words) in order to help maintain and/or repair a network of space-time anomalies in desperate need of maintenance and/or repair didn’t seem particularly controversial at the time I said it.
But enough of that. Veering back to grandiosity, Wouldn’t It Be Hilarious if “full quasar” had actually already happened in one of those wormhole pockets. I have not found any models of an expanding quasar. Nevertheless, I am confident that knowing it was coming would approach “impossible.” My suspicion is that the leading edge would have a shock in front that effectively severed the expanding burst from the observable universe - at least for a Very Long Time. Nothing inside the sphere would have a Plank’s worth of time, if that is even a thing, to get a message out.
Your idea of waiting 30 years before venturing inside the sphere might work. But black holes are not “really” infinitely small points - that is only where our present level of mathematical acumen (and by “our” I mean Caldari graduate assistants; those equations are certainly far beyond me) end up. The inside of a quasar would be similarly incomprehensible, again for a VLT.
We, or a precursor civilization, would know that something was terribly wrong. But neither we nor the precursor would have any idea of the cosmic threat fast approaching. I am not aware of any Gallente science fiction disaster reels which explore this intriguing scenario.
