If the frequency does lower abruptly due the redshifting, could we tell the difference between that and it just stopping?

The waves come from the circling, not the merge itself.

Yeah... But the singularity is hypothetical, we don't know if they exists. We know that blackholes exists, but how their inside's are is a different topic. And things don't just appear to be frozen when they approach the blackhole, they (from our perspectives) are frozen, they did not crossed it yet because of the time dilation.

That will demand a direct observation to answer

No. The escape velocity from "inside" the black hole is higher than the light speed. So, even if something happens "inside" the black hole to generate gravity waves, those waves will not be fast enough to escape.

But more important than that, the blackhole (IMHO) is an event that is happening, there is no "inside" yet, because the body that originated the blackhole is frozen in time, from an outside perspective, there's no singularity yet because as density goes up, the proper time from this object slows down infinitely close to zero. If you wanna know more about that perspective on blackholes, look for "frozen stars".

Castilian ia a region of Spain where the "Spanish" language comes from. But there is not the only language there, and there was repression against the other languages there, specially the basque language.

So, call that language Castilian ia also recognize that other languages exists within the country.

(I'm not spanish nor a speaker, so, I may be wrong)

SI is great, but if you reset everything (and lose all tech and most of knowledge), just create a new system. Embrace what makes SI great (easy conversions and a the nature-based properties) and do it over.

For length, use Hydrogen line when you advance your society enough. It's more universal than using 🌎 as a 📏.

Will you use the sea borders instead of the coastline to avoid the paradox?

I didn't even know that neutrons have an antiparticle. TIL

Edit: neurons -> neutrons
