Is it possible to instantiate an object of type Nothing in a program?

In Kotlin, the Nothing type represents a type with no values — it is used to denote functions that never return a result (for example, they always throw an exception or run infinitely).
It is impossible to instantiate an object of type Nothing because it has no values. This serves as a signal to the compiler that the execution of the program will not continue after such a function call.
Example:
fun fail(message: String): Nothing {
throw IllegalStateException(message)
}
Here, the fail function returns Nothing, and it cannot be called in a way that produces a value.
