A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a ...

Before atomic elements came together, less than a second after the Big Bang, if particles condensed into halos of matter, ...

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 ...

Cosmologists have traced the Big Bang’s earliest moments with great care, from the explosive inflation that set spacetime in ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

A research team proposes utilizing numerical relativity, a computational technique for solving Einstein's equations in high-gravity environments, to investigate the universe's origin. The approach ...

The Big Bang theory is supported by the discovery of the cosmic microwave background radiation. The universe rapidly expanded and cooled after the Big Bang. Light elements like helium and lithium ...

We’re often told it is “unscientific” or “meaningless” to ask what happened before the big bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...
