Earlier today, astronomers and physicists working on the BICEP2 collaboration announced results from their three year long experiment. Polarization measurements of the Cosmic Microwave Background radiation have revealed signs of gravitational waves. The experiment also provides some of the strongest evidence yet to support the inflation hypothesis first proposed by Alan Guth.
Unfortunately, I’ve been a little short on time this semester (as evidenced by the lack of activity on the blog over the past few months), so I don’t have too much time to dive into this exciting discovery. But I do at least want to point to some of the best explanations of the newly announced results:
- Physicist Sean Carroll provides an excellent (and technical) overview of the significance of the results here and here.
- Astrobites also provides a technical but good overview of the results here.
- The Guardian has a much more accessible article that highlights the significance of the results here.
- The actual data and results (and pretty plots!) from the BICEP2 collaboration are available here.
