Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the key information principle?Requires inherited information to be copied separately from physical replication for evolution
2. What is the galactic exploration concept?The theoretical 'von Neumann probe' could explore the galaxy by replicating itself
3. What is a self‑replicating machine?A self‑replicating machine is a robot that can build a copy of itself using materials it finds around it. It follows instructions inside it to make all the parts it needs and then puts them together.
4. How does a self‑replicating machine make a copy of itself?First it looks for raw materials in its surroundings. Then it follows its internal blueprint to shape those materials into parts, and finally it assembles those parts into a new machine that can do the same thing.

Automata Theory: A branch of computer science and mathematics studying abstract machines and computation problems.
Cellular Automata: A model of computation consisting of a grid of cells, each with a state, evolving based on rules.
Material Closure: The ability of a system to produce all its necessary components from available environmental resources.
