At least we astrophysicists hope so. After all, it’s hard to unravel the complexities of distant parts of the universe if we don’t know the basic rules. But what if this is wrong? There is a hint of evidence that the fundamental constants that govern our universe may evolve over time, and even from one location to another.Written by Graeme Gossel and Matt O’DowdHosted by Matt O'DowdProduced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangBITISMCoolAsCatsDavid NicklasRichard SenegorQuasarTambe BarsbayMeo Meow Oink OinkMayank M.
