At this level, it offers a near-perfect example of the very definition of esoteric.

There's probably a few thousand people on earth making contributions in this field. Calling it esoteric is probably fair.

Claiming it makes something think that they are taking the piss merely because it's hard to understand isn't really the reaction I'd expect on HN.

It's not that it's simply hard to understand, it's that the language used is fantastical - "imaginary black holes" is a pretty far out notion for many.

You're telling me that mapping "scrambled quantum particles" to "imaginary black holes in a higher dimension" is not esoteric?

From my reading those phrases are actually attempts to use terms a lay person can understand i.e. the opposite of esoteric. "Holographic duality" is the only phrase that is legitimately esoteric, the rest is just baby talk.

It started with Pythagoreanism https://en.wikipedia.org/wiki/Pythagoreanism. Continued with sacred geometry. And also holofractal is popular.

That's not what OP said. Is your claim that no field of mathematics is esoteric?

I was simply commenting in reply to the statement, "Any time I see this kind of esoteric research..."

My education in mathematics goes to calculus, and I am aware of the complexities of higher orders of mathematics such as what is used in physics, but I never had considered the field to be "esoteric".
