It was invented by John Wallis (1616–1703) who could have derived it from the Roman numeral M for 1000. But infinity does not do anything, it just is. “Daddy, what number is bigger than infinity?” “Nothing”, I replied. But one thing we know for certain: infinity is a lot bigger than 1000. I am most ready to listen to rebuttal but please hear me out. An idea of something without an end. So at last we have finally found a larger infinity than ℵ 0! There's only one and that's infinity, right? The Concept of 1 First the value of the whole number 1 as it compares to 0 is infinit… Is there anything bigger than infinity? No, there isn't a number bigger than infinity. The symbol for infinity is ∞, a horizontal 8. Is there a largest number? What is infinity? Although it has no width, it contains an infinite number of points. “Yes there is”, he said. Infinity is not a number; it is the name for a concept. Infinity is not a real number. Most people have sort of an intuitive idea of what infinity is - it's a quantity that's bigger than any number. What is infinity plus infinity? Numbers Bigger Than Infinity The prefix "trans" means "beyond". What is infinity plus one? Infinity is not "getting larger", it is already fully formed. Infinity is an adjective used to describe any number whose magnitude is larger than that of all finite numbers. Infinity does not grow. So I looked towards my wife and she confirmed it is in fact a number. Sometimes people (including me) say it "goes on and on" which sounds like it is growing somehow. It turns out there are many transfinite numbers. It’s the second transfinite cardinal number, and our first example of a bigger infinity than the ℵ 0 infinity we know and love. Infinity is well, infinite, so it never finishes. “Noooo”, he said, “It’s a number larger than infinity”. Wrong. There exists infinite numbers that are odd, infinite numbers which are even, and infinite numbers which are not integers, and these latter values are not even and not odd. Take a one dimensional line as an example. Infinity is not a real number, it is an idea. “A Google-plex is the name of the Google headquarters”. The concept of infinity is just a general concept, and the real mathematics is the study of transfinite numbers. Perhaps not surprisingly, this new infinity—the cardinality of the set of real numbers ℝ—is called ℵ 1. I am not convinced there is a number larger than the whole number (∞). “Nooooo”, I said to him. So a transfinite number is one that's beyond the finite. “Googolplex”.
