How can anyone agree on the age of the universe? And how can we be so confident if it’s all just a bunch of models? What if the universe is extra lumpy, does that change anything?
Why is math so effective at describing the universe? What is reality is made of math? What does it mean for us to be conscious beings in a mathematical structure?
What is the weak equivalency principle? How was antimatter discovered and why is it the perfect thing to put gravity to the test? What did the CERN experiment discover?
How does the double-slit experiment work? What does it teach us about reality and measurement if we try to mess with the experiment after it’s already started? How does quantum complementarity guide us with how to think about it?
What is causal determinism? What are some of the ways that physics can permit free will? What does emergence have to do with all of this?
