A resolution to this problem is offered by inflationary theory.

The image reveals the universe is 13.7 billion years old (within one percent error) and provides evidence that supports the inflationary theory.

Measuring the strength of this signal puts limits on inflationary theory.

In 1981, Andrei Linde developed another version of inflationary theory, which he called "new inflation."

This success in solving the flatness problem is considered one of the major motivations for inflationary theory.

In fact, a major prediction of inflationary theory is that omega will be found to be one.

One of the most severe challenges for inflation arises from the need for fine tuning in inflationary theories.

It has been shown that any inflationary theory with an unbounded potential is eternal.

Since the fluctuations are believed to arise from inflation, such measurements can also set constraints on parameters within inflationary theory.

The horizon problem may have been answered by inflationary theory, and is one of the reasons for that theory's formation.
