A new review argues that modern numerical relativity can push cosmology past its usual shortcuts and test ideas about what, if anything, came before the Big Bang. The approach is simple to state and ...

Asking what existed before the Big Bang is often dismissed as meaningless, since traditional physics breaks down when pushed that far back in time. Yet a new paper published in Living Reviews in ...

It is one of cosmology’s most perplexing questions: what happened before the Big Bang? Although the question has been debated for decades—with some even viewing it as a matter that should be left to ...
