I mean doesn't exist in the sense of it not being-- as is commonly implied-- a "thing" that is invisible to us. It does exist in the sense of being the name of an observed inconsistency with our models, but the theory he presented was that it is a failure of the models to accurately model what we already know about, rather than it being that there is something out there (invisible mass, undiscovered particles etc) we don't know what it is.

Just one guy though. I'm sure opinions differ.

Yes to vacuum energy.

I'm not suggesting that the interior of a black hole is a universe, or that our universe is the interior of a black hole, rather I'm asking about the plausibility of a black hole, given sufficient growth by vacuum energy (if it even happens), could be the source of another "big bang" within the same constantly expanding fabric of spacetime and that any and all universes exist - causally disconnected - within said fabric?

In other words "singularity" -> produce a "big bang" -> black holes emerge -> black holes begin "charging/expanding/building mass/energy" via interior vacuum energy -> any of these black holes at their "peak" energy/mass state ala "singularity" -> produce a "big bang" -> repeat ad infinitum.

Random or poorly thought out ideas are fine (this is a grand time-waster site, after all). What would be nice is if people framed it along the lines of being a novice seeking clarity, rather than their novice idea being "so obvious" or otherwise going to revolutionize a field countless people have spent a lifetime trying to resolve. Something closer to "I have this theory, does anyone know if it lines up with an existing theory, or if it is debunked/doesn't actually make sense (and if so, how)?" That would make it more clear that they are looking for the beginner's explanations for things.

I was going to say that this picture looks a little bit too close to witchcraft and wizardry for Florida.

Those of you missing my joke I'm referring to Harry Potter being on the list of books that are not being allowed in the schools. From what my small brain can understand, it it is because witchcraft and wizardry is anti-christian.

LIGO is currently detecting gravitational waves which warp spacetime. If these waves form crests and troughs then can't there be constructive interference and generate a very high peak? Certainly that would have an unusual effect. If dark energy is stretching everything apart, that's the expansion we observe, so surely there must be a size somewhere.

The article doesn't mention the other 'why', which is 'why are there so many people combing Antarctica for 'meteorites' at all? The answer is that China has sent dozens of 'meteorite hunting' expeditions to Antarctica over the years. In other news, Antarctica also has large fossil fuel and mineral reserves, but - no - it's definitely the space fragments they're looking for...
