👤 whose

Whose discovery showed that the cosmic microwave background is almost perfectly uniform but slightly clumpy?

Quick Answer

The COBE team, led by scientists including George Smoot and John Mather, detected tiny fluctuations in the CMB in 1992. Those ripples matched predictions about the seeds of galaxies.

The Full Story

The Cosmic Background Explorer, or COBE, measured the cosmic microwave background with unprecedented precision. In 1992 its team reported tiny temperature variations across the sky, showing the CMB is not perfectly smooth. Those variations are the fingerprints of the early density fluctuations that later grew into galaxies and galaxy clusters. George Smoot and John Mather received the 2006 Nobel Prize in Physics for this work.
