"Indeed, the existence of so many things, from dark matter to black holes to wormholes all has to be inferred. The Big Bang, too, is only provisional and seems to be waiting for a more graceful model to replace it. In Clegg’s words, the Big Bang theory 'has the feeling of something held together with a Band-Aid.' Whether what came before our universe was another universe or nothing, or something else yet unconsidered, for now the most accurate answer might be: We just don’t know."—Anthony Doerr, The Boston Globe
