Stars are stupid hard to measure with precision because there is a shit ton of interference between our observation platforms and them, and also because they are dynamic. Stars are constantly ejecting mass and blasting radiation that makes precise measurements difficult.

We can very easily tell that "that this is a big star", but trying to say "is it bigger then this other big star" is alot harder.

The fact that we can measure with imprecise but valid metrics a star light years from us is a miracle all on its own.

Is VY Canis Majoris still the biggest known star?

I think so.

Boötes Void and other voids are areas where superancient species have dyson-sphere'd nearly all stars in tens of thousands of galaxies in desperate search for ascension. There is none.

In our galaxy? It's probably up there, but it's hard to say for certain. It's also close to the theoretical maximum limit before they quickly rip themselves apart. They can get bigger, but not for long. Sometimes in a loop. Hypergiants are closer to a loosely held together mass of hot gas than a star like our Sun, it's a brief balance between the gravity of relatively low density gas and the immense pressure its luminosity pushes outwards.

As fun as that theory is, I think Universe "Space Climate" is to blame for the voids. The gravity of all the matter flows much like wind, it has cycles and as it flows voids where there is no wind forms.


Hard to prove though, because "universe climate" is something that would play out over hundreds of millions of years.

Sadly, yes. Structures like voids and walls and clusters are reasonably explained by relatively ordinary processes.
But it'd be more fun if they were causes by ancient species desperate to grow beyond this universe.
