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. It explains why ...

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 ...

Amid simmering anxiety about the future of federally funded science, the U.S. government has quietly withdrawn support for cosmology’s next premier project, an experiment that would have given us the ...

A recent resurgence of interest in a bold cosmological theory has reignited debate about the nature of dark matter, the Big Bang, and the possible existence of a mirror universe. Originally proposed ...

A new theory promises to simplify our approach to the universe's earliest moments, but some cosmologists say further mathematical scrutiny is warranted. reading time 5 minutes Following the Big Bang, ...

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 ...

Last year’s reports that the BICEP2 telescope had uncovered evidence for cosmic inflation turned out to be a false alarm, but researchers in the field haven’t given up. Matthew R Francis describes how ...

The BICEP2 telescope at twilight, which occurs only twice a year at the South Pole. It's not every day that a new window on the birth of the universe is thrown open. It's not every day that human ...

We'll cut right to the chase: This video of Stanford Professor Andrei Linde finding out about yesterday's big discovery of "smoking gun" evidence of cosmic inflation (the "first tremors of the big ...

Update 12:05 p.m. — The team at the Harvard-Smithsonian Center for Astrophysics has announced they've found "The First Direct Evidence of Cosmic Inflation." The scientists say that after three years ...
