Or so I am told:
…those gravitational wave results point to a particularly prolific and potent kind of “inflation” of the early universe, an exponential expansion of the dimensions of space to many times the size of our own cosmos in the first fraction of a second of the Big Bang, some 13.82 billion years ago.
“In most models, if you have inflation, then you have a multiverse,” said Stanford physicist Andrei Linde. Linde, one of cosmological inflation’s inventors, spoke on Monday at the Harvard-Smithsonian Center for Astrophysics event where the BICEP2 astrophysics team unveiled the gravitational wave results.
Essentially, in the models favored by the BICEP2 team’s observations, the process that inflates a universe looks just too potent to happen only once; rather, once a Big Bang starts, the process would happen repeatedly and in multiple ways.
There is more here. How should this change my behavior? Should I feel more or less regret? Take more or fewer risks?
