Veritasium: We simulated if you can really reach anyone in 6 steps

We dive into the six-degrees-of-separation idea with hands-on simulations, showing how a few random “shortcuts” and weak ties turn any sprawling network into a surprisingly tight world. From disease-spread models to Strogatz’s viral sharing demo, you’ll see why six steps really can link you to just about anyone.

Then we explore why hubs (thanks, Barabási!) dominate network structure, how preferential attachment fuels their rise, and even throw in the Prisoner’s Dilemma to prove that your individual choices can literally rewire the global network.
