How many echoes does it take to make a Big Bang?

No idea? NASA's Dr. John Mather who won the 2006 Nobel Prize in Physics for measuring the echoes of the Big Bang and understanding how it happened, has answers. This is part of a new YouTube Q&A series called: "Ask a Nobel Laureate" hosted on the Nobel Prize YouTube channel.

Submit your question for Dr. Mather by attaching it as a video response to his call-out. How was the universe created? What does space smell like? Is there life on other planets?

Questions are due by October 30th, and should be less than 30 seconds. A selection of questions will be answered via video and posted to the Nobel channel.
