In this scenario, the universe’s current expansion was preceded by a phase of contraction, yielding similar benefits to inflation. The group’s fight against inflation isn’t news.

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

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

Inflation requires that the universe be filled with a high density of energy that gravitationally self-repels, thereby enhancing the expansion and causing it to speed up.

The study suggested that our universe formed from the collapse of a black hole, inside a bigger parent universe, rather than a sudden appearance.

Inflation may be the best-developed explanation for many features seen in the modern universe, these researchers say, but it still has problems. Science News headlines, in your inbox ...

In inflation, by contrast, the whole universe could have fit into a Planck volume, 10-33 centimeters across, much tinier indeed. So for some people (like me), the benefit of inflation isn’t that it’s ...

Astronomers have found the first direct evidence of cosmic inflation, the theorized dramatic expansion of the universe that put the "bang" in the Big Bang 13.8 billion years ago, new research ...

Inflationary theory dates to the late 1970s and early 1980s, when physicists were trying to understand why the universe is so uniform at the largest scales, including the cosmic microwave ...
