Cosmologists Search for Gravity Waves to Prove Inflation Theory
During the next decade, cosmologists will attempt to observe the first moments of the Universe, hoping to prove a popular theory. They'll be searching for extremely weak gravity waves to measure primordial light, looking for convincing evidence for the Cosmic Inflation Theory, which proposes that a random, microscopic density fluctuation in the fabric of space and time gave birth to the Universe in a hot big bang approximately 13.7 billion years ago. A new instrument called a polarimeter is being attached to the South Pole Telescope (SPT), which operates at submillimeter wavelengths, between microwaves and the infrared on the electromagnetic spectrum. Einstein's theory of general relativity predicts that Cosmic Inflation should produce the weak gravity waves ...
