 SOCRATES: The big bang theory, the standard model of cosmology, says that our universe, meaning all of us, came from an almost infinitely small point. Do you remember the comedy of Borges with two point-dwellers? From a point about fourteen billion years ago, spacetime began to expand, an event called the Big Bang. This expansion is still going on due to the explosive energy of the Big Bang, our universe is still getting bigger day by day. But when I go to tell this to the gods of Olympus, they ask, what was before this big bang or how did this big bang happen? If the gods ask such questions, what will happen to mortals? SOCRATES: The big bang theory, the standard model of cosmology, says that our universe, meaning all of us, came from an almost infinitely small point.

 RHEA: I have another question about the figure of the EM spectrum. In order of wavelength, radio light is the longest, followed by microwaves, infrared, visible, ultraviolet, and X-rays, and gamma rays the shortest. The shorter the wavelength, the higher the frequency, the higher the energy. When did people discover this vast range of light? RHEA: I have another question about the figure of the EM spectrum.
