Last week, a group of scientists working with data from the BICEP2 telescope in Antarctica reported that they had observations that provide strong evidence for a Big Bang at the start of the universe, leading to cosmic inflation. These observations indicated the existence of gravitational waves, which support the inflation theory and contradict other theories. This is the first time that we’ve seen strong evidence for a theory of cosmic origin, and it’s very exciting to be able to finally explain how the universe looked close to its origin. Here’s a collection of articles from Scientific American that explain more about the new finding, cosmic inflation, and why it matters: Cosmic Inflation and Big Bang Ripples In-Depth Report
SEL’s Tallman Science Today Collection contains books that feature popular or semi-technical discussions of scientific and technological concepts, making it easier to read about subjects that might not be in your field. Here are some resources from the Tallman Collection relating to gravitational waves, cosmic inflation, and the nature of the universe:
- Ashtekar, Abhay, ed. 100 years of relativity: space-time structure: Einstein and beyond.
- Coles, Peter. Cosmology: a very short introduction.
- Greene, Brian. The fabric of the cosmos: space, time, and the texture of reality.
- Hawking, Stephen. A briefer history of time.
- Hogan, Craig J. The little book of the big bang: a cosmic primer.
- Kennefick, Daniel. Traveling at the speed of thought: Einstein and the quest for gravitational waves.
- Kragh, Helge. Conceptions of cosmos: from myths to the accelerating universe: a history of cosmology.
- Tyson, Neil deGrasse. Death by black hole and other cosmic quandaries.
The Tallman Collection can be found in SEL/EMS at Boelter Hall, across from the new book section. If you would like more help with the library resources or about research questions in general, please contact a Science and Engineering Librarian.
