Aye, but here’s the rub: there’s no such thing as 10 ^-52 metres. Nothing can be shorter than the Planck length.
“Nothing can be shorter than the Planck length.” So, his math cut a very short planck ... measure twice cut once. {No thing shorter because of dimension space restriction ... without time events do not occur and without space things do not exist.}
