Binaries in science and i do mean ANY Binary… stuff almost always is on a spectrum or theres otherwhise some uncertainty or weirdness in between… just look at states of matter. How many small states there are over a simple thing we first thought was just solid or liquid as a simple example.
It is rare things are just black or white.. barely any binary has ever held up to science, whereever you find one you can be certain we just didn’t look deep enough yet.
Basically if you accept pretty much any thing as strictly binary probably in the future you will be proven wrong because shit is never simple…this holds true for even super small quantum scales too. Anywhere we look binaries just don’t hold up.
