>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.

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.

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".
