This feature and other mysteries in the observations may point the way toward new theories of physics, say scientists who met recently to discuss the implications of the findings.
Three Planck team members will answer public questions about the Planck data during a Google+ Hangout on Wednesday (July 31) at 3 p.m. EDT (1900 GMT), sponsored by the Kavli Foundation. You can watch the Hangout live here on SPACE.com. Questions for the researchers can be submitted in advance by emailing email@example.com or posting on Twitter with hashtag #KavliAstro.
Planck measures ancient light pervading the universe called the cosmic microwave background (CMB), which dates from just a few hundred thousand years old. This light records a record of what the universe like shortly after its birth in the Big Bang, and thus offers a test of theories of how the cosmos came to be.
