Simulations based on Einstein’s theory of relativity test scenarios that might have preceded the Big Bang, to observe the ...

The evidence for the Big Bang is overwhelming, but we cannot describe what goes on in that event. We can’t accurately call it ...

What if the Big Bang wasn’t truly the beginning? A team of cosmologists is using the power of supercomputers to push past the ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of ...

Most scientists think that everything that we know and experience began with the Big Bang, 14 billion years ago. But how can ...

The review shows how numerical relativity transforms cosmology, replacing shortcuts with full simulations of Einstein’s ...

Researchers are using supercomputer simulations grounded in Einstein’s relativity to test scenarios about what may have ...

In the earliest moments after the universe was born, everything changed—fast. This rapid expansion, known as cosmic inflation, was theorized to solve problems in the Big Bang model.

Today’s standard cosmological model, based on the Big Bang and cosmic inflation (the idea that the early universe rapidly blew up in size), has been remarkably successful in explaining the structure ...

But research into cosmic inflation—the lightning-fast expansion that likely occurred before the Big Bang itself—has complicated that view.

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led ...

The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if ...
