"Einstein cast gravity not as a force but as the geometric bending of space and time. In a popular analogy, the fabric of space-time is like the flat expanse of a mattress, and a massive object like a star is like a bowling ball sitting on top. The weight of the bowling ball compresses the mattress, forming a dimple — matter tells space-time how to curve.
In this analogy, a planet is like a smaller ball. If it rolls close enough to the bowling ball, its path will be altered by the dimple in the mattress — space-time tells matter how to move."
This analogy is wrong in a way that even people who've studied physics often don't realize.
On an everyday scale like the Earth orbiting the Sun, almost none of that gravitational interaction is from the bending of space. Far beyond 99% (actually, about 99.999999%) of it is from the bending of time.

Greek 'anameixi' loosely means a mixture or a blending. The special states could be called 'anameixic', the property could be called 'anameixicity'.
Why am I trying to find a name for this? Otoh, why are so many physicists trying so hard to popularize their projects for the last 40 or 50 years? Oh .. I think I just answered my own question.

That is an incredibly unfortunate term to use for the phenomenon.

They can choose any word to name a new feature; and they choose "magic"... Next one, it'll be "dark magic".

Calling something 'magic' is like an admission that you have no clue about what is going on. Seems to me, they do have some clue, namely that instead of codes with perfect isolation, there might be some advantage to studying ones that allow some blending. The resulting spaces may (or may not) lead to a better description of reality, but doing science means to peel back that mystery. So to go and promote this under the term 'magic' is disingenuous.

IMHO, as an analogy, matter is not 'a bowling-ball on a mattress', but more like a scrunched-up section of table-cloth. Tiny knots or whirlpools of space-time/quantum fields, different particles are different topologies of knot, albeit the nature of space-time is unclear and it may well be a projection.

>In holographic theories, physicists may have traced the pliability of space-time to its quantum roots
...ah yes holography again. Not to say that all these insights from it are completely worthless, but unless we actually find a holographic dual of our universe instead of AdS spaces (which are the opposite of our universe if anything), this whole field is starting to feel more like a jobs program for mathematicians out of new ideas.

So, when it comes to the quantum physics of dark matter, would this property be dark magic?
I’m so sorry. Couldn’t help myself.

I gotta say every aspect of this headline reads like bullshit. Unfortunately
