This Week in Lex Fridman Podcast (May 25 - May 31, 2026)

This week, the Lex Fridman Podcast explored fundamental questions that remain at the edges of physics understanding. Don Lincoln, a physicist at Fermilab, discussed the major unsolved mysteries—antimatter asymmetry, dark energy, and the search for a theory of everything—offering perspective on what we know, what we don't, and why these gaps matter. The conversation highlighted how the biggest advances in physics often come not from answering questions, but from discovering which questions are worth asking.
