Well at one time people “knew” that space was filled with Aether, and people knew that the universe was no more than 2 million years old.
But once you understand things more, some of the things you know turn out to be wrong.
In this case it’s more like “we called this thing a planet before we knew just how tiny it really is but it’s still cool so we now have categories for things just like it”
Which I think is neat.
You can be sad it’s not a planet, we can also be happy that it pulled one over on all of humanity for such a long time.
the only thing that changed is what we call it, pluto has existed since before humans and will continue to exist after humans most likely, and it does not give even the tiniest shit about what we call it.
“planet” is an arbitrary category that mostly just exists because we like to put things into categories, much like the concept of a continent.
It’s just really difficult to say that pluto is a planet if we want to have any sort of vague definition for what a planet is, because pluto is more similar to a ton of objects in the solar system than it is to the other bodies we very confidently refer to as planets.
If nothing else you have to also call ceres a planet if you include pluto, and how many people give a shit about ceres?
There was an episode of PBS Space Time on the holographic principle in general recently, and I believe they’ve also discussed the black hole thing as well.
Or that the observable universe could be inside of a black hole. Don’t watch too many black hole videos before bed.
Planet 9 is not a primordial black hole and it can’t hurt you. 🙀
From my understanding of primordial black holes, if one were so close as to be in our solar system, it is very small.
Since it’s so small, it would have fizzled out through hawking radiation output a long time ago.
So yes, planet 9 is NOT a black hole that can hurt you.
Now, a pocket of warped spacetime that will one day spawn a Chaos Demon? Maybe.
It still fucks with me that we went from 9 planets to 8, pour one out for Pluto

There are SO MANY Men In Black references in this thread and NOBODY is pointing them out and it is driving me CRAZY
That’s actually what I was going for but I didn’t want to use the “earth was flat” that K uses.
Ok thank you, that makes me feel a lot better to know that at least you intended the reference.
Pour one out for Ceres, for being downmoted so long ago people forget it was a planet.
Pour one out for Makemake and Hamuhea, for being discovered so recently they never got to be planets.
That’s messed up

I thought I heard once that our universe could be a holographic projection on a 2D plane surrounding around a black hole.
Don’t ask me for any details further than that, because I do not remember.

Projected by what?
I don’t remember.

My understanding is its similar in difference to a protostar and a nova
