The chapter explores the perception of color, including how our brains interpret red and blue cones as violet, even though it's not between them on the spectrum. It discusses the physics of light wavelengths, biology of color perception, and the role of quantum mechanics in vision. The conversation transitions to the speed of light, touching on the limitations for objects with mass to reach or exceed that velocity, tachyons as theoretical faster-than-light particles, and the implications of tachyons moving backward in time.
Could the universe be composed of a single electron? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly answer grab-bag questions about the multidimensionality of time, quantum chromodynamics, gluons, tachyons, and more with astrophysicist Charles Liu.
