Chapter 12: Feasibility

"The so-called closed timelike curve supercomputing model is a hypothetical concept,"

"It can be divided into multiple types, but no matter which type it is, they all involve the concept of the temporal dimension. Generally, they can be divided into retro-causal closed timelike curves and infinite-temporal closed timelike curves."

Lu Yuanming was trying very hard to read the book in his hands while also constantly looking up at the blackboard where an expert was rapidly writing down formulas and explaining everything to him on the side.

"… In the last lecture, we talked about the limits of computational domains. There is a limit to any physical computation, namely Bremermann's limit."
