Vsauce built a huge following on YouTube with Michael Stevens presenting science and curiosity driven questions in a distinctive, enthusiastic style. That recognisable delivery made his voice and persona easy material for parodies and meme edits online. This sped up rap style version strips away the lesson and keeps only the familiar energy, which is why it travels well on Instagram, in short edits and on soundboards. People reuse it not for information but for instant recognition, using the contrast between a smart presenter style and complete nonsense timing as the joke itself.
