Resumen de Infinite frontiers
Travel any distance in modern fundamental physics and people will soon find themselves in the multiverse. Some of their most successful theories, from quantum mechanics to cosmic inflation, lead to the conclusion that our universe is just one of many. The journey into this confusion of worlds starts in people's own. The universe they call home was born from the big bang some 13.8 billion years ago, during which time light has traveled further than they might expect--47 billion light years, thanks to the universe's ongoing expansion. Hall discusses how people can navigate through the multiverse.
