hmm. the fifth domain. the final domain. there seem to be five domains, if you’re counting using the real number system. imaginary numbers include the square root of negative and infinity. is null or nought an imaginary number? it seems easy to prove that null is not zero, and zero is a real number. so is the null domain a countable domain? are there six domains or is the null domain not countable leaving five domains? is the fifth domain infinity? is the null domain the square root or negative one? is something always built on a foundation of nothing? is it a fundamental paradox? is the 1st domain the smallest domain we can count? mathematics does not seem as well suited to analyzing the universe as it first seems to be. otherwise the singularity wouldn’t exist. the singularity seems to be the null domain. even stephen hawking refused to analyze the singularity. he needed a different domain of mathematics to explain it. does mathematics have a null domain? a place where it doesn’t work? yes. that seems clear. that’s the paradox. the null domain defies explanation and defies counting. yet somehow, it doesn’t exist and yet everything is built upon it. einstein seems like he gave up. he called it god in the end. stephen hawking seems like he gave up, but maybe he didn’t. maybe he just died before he gave an answer. i accept that he accepted imaginary numbers. i accept that he also accept that null is an imaginary number, domain structure, uncountable though it may be.
