there are a few infinities. one is wondering how far the line of time extends before our apparent present and after it. one is how far our universe goes. one how massive we are compared to the ant, how massive the mountains are compared to us, how massive the planets are compared to ours. more than one musical infinity, like how high the pitches go above and below our human ear. my fave infinity is the artists who come out of nowhere and reinvent the whole thing to something that was previously unimaginable.
