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.

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, ...

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

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

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 ...

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 universe goes whoosh, and inflation does its thing. But then, the inflaton (somehow) changes and reduces its vacuum energy, shutting off the inflationary epoch.

Evidence for Universe Inflation Theory May Lurk in New Data. News. By Katia Moskvitch published 21 January 2014 When you purchase through links on our site, we may earn an affiliate commission.

I was reminded recently that we live in a Catch-22 Universe. What makes it a Catch-22 is that no one is qualified to penetrate the mystery of the cosmos without skill in advanced mathematics, and ...

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 ...
