Summary

In this StarTalk episode, Neil deGrasse Tyson and comic co-host Jordan Klepper are joined by string theorist Lara Anderson to discuss the search for extra dimensions. They explore the basics of string theory, which proposes that fundamental particles are one-dimensional ‘strings’ whose vibrations determine their properties. The conversation covers the Higgs boson, the challenge of quantum gravity, and why string theory requires ten dimensions for mathematical consistency. Higher-dimensional objects, such as membranes, and the visualization of extra dimensions through shadows are discussed. The possibility that black holes might be higher-dimensional objects intersecting our spacetime is considered. They also touch on celestial holography, the nature of time, and whether dimensions are real or merely mathematical constructs. Throughout, Anderson provides accessible explanations, and the dialogue balances scientific rigor with humor.
