In our written language, the symbol for infinity is an 8 rotated by 90 degrees, probably because this symbol could theoretically be drawn infinitely often without beginning or end. It has no beginning and no end - unlike a 5 or a 1 or a 7. But I find the word 'infinite' more exciting. I don't know of any alternative term in the German-speaking world. Infinite actually expresses the complement of finite, so it needs its opposite. For example, there is light and its complement dark, or near and far. But I only know the opposite of finite as infinite. Maybe it's because everything in our lives, in our world, actually has an end. A beginning and an end, birth and death. We all have an expiry date, we are all basically terminally ill, even if we are seldom aware of it. When I think about it, I find a contrast to finitude: resurrection.
I wish you an extraordinary day!
