NO! No no no no no! Crap, there's no way I am going to be able to stem the tide of ignorance already flooding over the internet. THIS IS FANCIFUL RUBBISH. The human-scale stuff is fine. I am not an astrophysicist, so I cannot confirm the large-scale stuff, though it looks plausible. However, the only reasonable statement below the atomic scale is the statement at 1 fm saying "lengths below this scale are unconfirmed". Everything at smaller scales is just "I read that there are some particles, & I need to put stuff at various stages, so I'll just put things in at random". Only a subset of the known particles are mentioned, & they are given completely arbitrary sizes that make no sense (especially since the size of subatomic particles is a very poorly-defined concept). Then some speculation is thrown in at the very smallest scales. Please do not promote the fiction that these charlatans have produced. Please stop. Please.
