Alan B. Guth

Alan B. Guth is a theoretical physicist best known for developing the concept of cosmic inflation—an idea proposing that the universe underwent an extremely rapid expansion in its very early moments. This theory helps explain the large-scale uniformity and structure of the universe we observe today. Guth's work has profoundly influenced cosmology by addressing questions about the universe's origins and its large-scale characteristics. His contributions are fundamental to our understanding of how the universe evolved from a tiny, hot, and dense state to the vast cosmos we see now.
