What is cosmic inflation?
CosmologyEarly Universe
Quick Answer
Cosmic inflation is the idea that the early Universe underwent a brief period of extremely rapid expansion. It was proposed in the early 1980s to explain several features of the cosmos.
The Full Story
Inflation suggests that a tiny fraction of a second after the Big Bang, the Universe expanded exponentially fast. This idea helps explain why the Universe looks so uniform in all directions and why its geometry is nearly flat. It also offers a mechanism for tiny quantum fluctuations to grow into the structures we see today. The theory was developed by Alan Guth in 1980 and later refined by others including Andrei Linde and Alexei Starobinsky.
