An interfinity question is a question that has both an infinite number of answers and no answer at all. Interfinity allows opposites to coexist.
In written conversation the interfinity mark* indicates that the question should be understood on a secondary level in which interrogative and infinite expressions are combined. The interfinity mark differs from the short-lived percontation point, invented in the late sixteenth century to indicate rhetorical questions, in that it denotes ever-lasting and ever-occurring questions:
Is there life beyond planet Earth?
Does god exist?
Am I awake or am I dreaming?
Is there life after death?
What is the meaning of life?
Was this article helpful to you?
Where do you find your inspiration?
What is your dream project?
What are you unrealized projects?
Are you happy?
In a typographic sense the interfinity mark can be described as an interrogative punctuation mark formed by superimposing a vertical infinity mark (∞) with a question mark (?).

The interfinity mark was first used in Everything You Always Wanted to Know About Curating (2010), a book of interviews with a curator who always has the question mark handy.
Interfinity mark to be implemented into all RP fonts in near future.
