Paul Steinhardt, one of cosmic inflation's co-founders, turned against the idea decades ago. Today, he's more opposed to inflation than ever.

Cosmic inflation is what happened before, and set up, the Big Bang. Here's what it's like to live in an inflating Universe.

Generally regarded as one of the most successful theories about the early universe, inflationary cosmology is not exactly under attack. But a few scientists are questioning whether it deserves its ...

Does inflation tell us why the big bang happened or how the initial patch of space was created that eventually evolved into the universe observed today? The answer, again, is no. Click or tap to ...

NASA telescope will study what put the bang in the big bang The SPHEREx space telescope will explore the universe's origin and gather data on cosmic inflation.

And supporters of the universe inflation theory say that it might prove that the seeds of today's universe can be found in quantum physics.

The most incomprehensible thing about the universe is that it is comprehensible,” Albert Einstein once pondered. But even as ...

The early universe experienced a phase of rapid expansion, known as inflation. For decades, cosmologists assumed that this expansion was powered by a new entity in the universe, known as the inflaton.

Paul Steinhardt pointed out an interesting sociological fact: twenty years ago, you had a coterie of theoretical early-universe cosmologists who had come from a particle/field-theory background, ...

By replacing traditional curvature with a quantum potential, this model is consistent with the observed flatness of the universe and naturally leads to a robust inflationary period.
