Side-note: IIRC, the old
Rihannsu novels by Diane Duane called the Romulan star Eisn. I'm stealing that name when I need to use a proper noun, even if it's non-canonical.
@Christopher to refute your point, while it's true civilian and spy installations could detect changes in the makeup of the romulan sun, don't discount the Romulan governments ability to downplay the data.
Amongst the Romulan population, maybe. (Though "Unification" made it clear that there are Romulan dissidents who don't believe or trust their own government.)
Amongst Federation and Klingon and Cardassian and Ferengi and Tholian and Talarian and Breen and Tzenkethi scientists? No fucking way.
Romulans are very good at hiding what they want hidden.
You can't hide a star.
Eventually, the Federation would find out, you are correct. But it would take them time to refine their data,
That's like saying "Eventually the U.S. would find out that the Kremlin was on fire, but it would take them time to refine their data to see the flames." It's nonsense. You can't hide the kinds of energies being emitted by stars on the verge of going supernova.
especially if they have no reason to be specifically monitoring their sun.
It's the star system of the capital planet of the Federation's oldest rival. I promise you,
I promise you, at any given moment, Starfleet Intelligence alone probably has dozens of subspace telescopes aimed at Eisn, Just In Case. And they probably have since the Federation was founded.
And that's to say nothing of the millions of astronomers who would also be studying Eisn for purely scientific reasons at any given moment.
My argument is that the Romulans would have several years of stonewalling before the Federation figures out what's really happening.
Your argument is obviously built on the fact that you don't understand how astronomy works.
All our detectors relying on TODAY, 2020 technology, use information gathered at the speed of light. Unless the federation has some reason for using FTL sensors on Romulus,
Gosh, what POSSIBLE reason could the Federation have for wanting to use long-range FTL sensors on the capital system of a rival power that has gone to war with the Federation or tried to attack it multiple times across two hundred years??
I can't possibly imagine why they might do that!
any standard astronomical data gathered would be years old
I have no idea why you think anyone wouldn't be using FTL sensors as a matter of course for precisely that reason.
I stand that it is eminently plausible that the Federation doesn't know shit about what's going on deep inside Romulus's sun.
No, you just don't know shit about how astronomy works.
You are correct. A star and a nuclear plant are different things. Now do you have a better example showing how real-world politics deals with such issues of disasters & secrecy?
A much better comparison would be to a hurricane and to how governments react to such things.
You can't
hide a hurricane, but you can prepare for one -- or
refuse to prepare for one, and then try to spin the consequences of those choices.
If the Romulan government tried to stonewall their public from knowing about Eisn's fate for a time before it happened, I would in particular think it appropriate to compare the Eisn supernova crisis to the events surrounding the landfalls of Hurricane Katrina in New Orleans in 2005 and of Hurricane Maria in Puerto Rico in 2017.
