The Void Type in Type Theory

#type-theory #computation #functional-programming #logic

Examine the properties and uses of the uninhabited type in theoretical computation.

Describe the Void type (or Bottom type) in type theory, a type that has no inhabitants. Explain its role in signaling unreachable code or terminal errors in a program. Discuss the theoretical relationship between the Void type and the concept of proof by contradiction in logic (Curry-Howard correspondence).
