Afterglow of the Big Bang May Be Related to "Collossal Structures," Scientists Say

Colossal structures larger than the visible universe – forged during the period of cosmic inflation nearly 14 billion years ago – may be responsible for a strange pattern seen in the big bang's afterglow, says a team of cosmologists. If confirmed, the structures could provide precious information about the universe's earliest moments.

In the first instant after its birth, the universe is thought to have experienced a rapid growth spurt called inflation. During this period, space itself expanded faster than the speed of light.

Inflation solves some cosmological puzzles, such as why relic radiation from the big bang, released when the universe was less than 400,000 years old, is relatively uniform.
