@lemmy.worldWe know that light and even gravitational waves propagate at the speed of light.
So if something catastrophic happened to the black hole at the center of our galaxy (about 26,000 lightyears away), would there be any way for us to have advance knowledge of it before we could observe it with telescopes or before we could measure the gravitational changes?
Ludicrous example: say the black hole at the center of the galaxy disappeared 25,999 years ago. Is there a way we would have known about it by now, or do we just have to wait out another year to see if we're all screwed?

Im guilty of accasionally expanding an NSFW photo to satisfy curiosity, but once it's open I can't figure out how to collapse it again without scroling past it a bit. Is this the only way or am I missing an easier gesture to re-collapse it?
As the title says, I don't have PlayStation+, and it's not required for playing Diablo IV on PlayStation. But, every time I open the game, it pops open a subscription page to subscribe to PlayStation+. I can back out of it, but it's starting to get annoying. Is there a way to prevent that popup?
