400,000 of you showed up for physics with no compromises, so I did something different for the milestone. No highlight reel. I took your hardest questions live and answered them, then got honest about the part of this job nobody asks about: the discipline behind running a serious science podcast.

We get into why clocks didn't tick differently in the early universe, what it actually means that the Big Bang happened everywhere at once, and whether JWST has any real shot at catching a Population III star before it's gone.

Then it gets contested. I make the case that language models may rediscover physics before they rediscover mathematics, walk through why enormous numbers do not get you to alien life, and look at the moment Avi Loeb quietly softened his ʻOumuamua position.

In this conversation:

    Why the early universe didn't run on a different clock
    The Big Bang as an everywhere-at-once event, not an explosion in space
    JWST and the hunt for the first generation of stars
    Whether an LLM could rediscover Einstein, and what that would mean for who controls discovery
    Why I read every book my guests write, and why that habit is the channel
