It explains why your physics-inclined friends are so happy recently. The guys behind the discovery spent a few years at South Pole and looked up the sky with a telescope. It may be the strongest evidence for the Big Bang theory and the inflation period at the start of universe.
Basically they look at the sky and collect the light. They analyse the light in term of one of its polarization modes (called “B-mode”). Inflation theory says that the universe expands extremely fast (even faster than speed of light) just after immediately the Big Bang happens. If it were true, the rapid expansion will leave a “fingerprint” on the light. Now we found it, the evidence is even stronger than what we need. The co-leader of the project Clem Pryke (University of Minnesota) says: “”This has been like looking for a needle in a haystack, but instead we found a crowbar.”
We are expecting new journal papers on that discovery very soon.
