Brian Greene has done some better stuff than "BSM."If you have not read Neil Degrass Tyson's book- Astrophysics for People in a Hurry (Astrophysics for People in a Hurry Series)
consider downloading your tax funded local library's app and give it a read or listen -
But it is fascinating.
String Theory still does not meet the level of a Theory. Conjecture... maybe. Many say "String Religion." But there is probably a pony in there somewhere!
Cosmology is fascinating! A great series (Free on YouTube) -- Stephen Hawking's Universe. C. 1996 or so. Still highly relevant. Beautifully done.
25 years later, still amazing.
