The Importance of Understanding the Physics of Information

In the book, Kyara, you mentioned this thing called that it's theory, you made it up. It's not necessarily a real thing, but it's this thing called dust that only interacts with our universe through gravitation or something along those lines. That would then violate the theory of interoperability and there would be no way to build a universal computer in such a universe. Did I understand that correctly? And then that was kind of inspired by dark matter, right? Because that's like one of the theories of dark matter is that it's just like what you call dust. Yeah.
