The Holographic Principle AKA Holographic Universe Theory, Astrophysics:
A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D ‘reality’ (plus time) is contained in a 2D surface on its boundaries. (https://www.southampton.ac.uk/news/2017/01/holographic-universe.page)
I don’t think I understand this one very well at all, and I did not have time this week to read any recent astrophysics textbooks. But I do understand the Magic: The Gathering death magic version, because I invented it.
Are you now, or have you ever been, a graduate student or professor? Are you highly learn-ed in specialized knowledge? Do you read dense theoretical texts for fun? Send your favorite theories to firstname.lastname@example.org, and I will draw them. Esoteric terminology also accepted but will be evaluated on a case-by-case basis. Oh, and follow me on Instagram while you’re at it – devon_isadevon.
