The phrase "infinity what on earth are we thinking" seems to express a sense of wonder or confusion about the concept of infinity. Infinity is a mathematical and philosophical concept describing something without any limit or end. It often challenges our usual way of thinking because it's not a number we can reach or fully comprehend—it represents endlessness in quantity, size, or extent. If you're asking what humans think about infinity:
- In mathematics, infinity is used to describe unbounded limits, such as infinitely long lines or endless sequences.
- Philosophically, it raises questions about the universe, time, and existence.
- Emotionally, it can inspire awe, fear, or curiosity about the unknown.
