Physics
The physics coverage favors the honest shrug over the tidy answer. A Fermilab scientist spends thirty years hunting dark matter and admits he still has no idea what it is, and explains why time is stranger than intuition allows, while a veteran theorist leans on decades of hard physics to argue we are probably not living in a simulation.
Don Lincoln Has Spent 30 Years Looking for Dark Matter and Has Absolutely No Idea What It Is
The Fermilab physicist makes a compelling case for something he cannot find, cannot name, and cannot stop thinking about.
Don Lincoln Wants You to Understand Why Time Is Weirder Than You Think
A Fermilab physicist walks Lex Fridman through the history of spacetime, and the most interesting part is what nobody actually understands.
Michio Kaku Says We're Probably Not in a Simulation, and He Has 71 Years of Physics to Back It Up
The string theory co-founder visits Diary of a CEO and does something rare: he actually answers the big questions, then politely dismantles one of the internet's favorite cosmic theories.
Michio Kaku Will Not Tell You Whether Aliens Exist, No Matter What You Threaten
The theoretical physicist comes prepared with one answer for every question: maybe.
