So it turns out that last week’s choice of the CMB as a topic was a particularly presient one, as this week’s science news is dominated with a story that has a lot to do with these all-important photons. If it proves to hold up to scrutiny, BICEPs detection of B-Mode gravitational waves may be the biggest physics story of the year. It has implications for theories of inflation, the big bang and even quantum gravity. It even may be the first sign on our roadmap to a “grand unified theory”, and it all comes from the Cosmic Microwave Background!
As promised, this week I will be explaining how and what we measure when we look at the CMB, and what that can tell us about the history of our universe and what we can discover about the universe we live in today. However, the idea behind this blog is to cover The Interesting Part of the science stories making the headlines, and the fact is that The Interesting Part of BICEPs potential discovery is… well… all of it! So in the next couple of days I’m also going to try and write some bonus posts on topics such as Gravitational Waves, Inflation and Energy Scales, to try and get to the heart of why BICEPs results have the potential to be so important.
