    "Konig's Lemma" essentially says that every infinite tree contains an infinite path.

    I didn't know that myself until I read your question, went to "google.com" and entered "Konig's Lemma". I recommend you try that yourself.

    What about the tree which consists of a central point, x, with infinite points around it connected only to x?

    Why is this not counted as an infinite tree?
