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.
