And it's even worse, they argue, inflation is not even a scientific theory: “[I]nflationary cosmology, as we currently understand it, cannot be evaluated using the scientific method.” As ...

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 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 standard model, although successful in the explanation of cosmic microwave background radiation and the large-scale structure of the universe, relies on unobservable entities such as inflationary ...

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 ...
