Following a thorough peer-review process, the researchers who previously announced the detection of B-mode polarization in a patch of the microwave sky have published their findings. Their research provides some evidence that the signals they have found may be the result of gravitational waves from the earliest moments of the universe's existence and thus might constitute the first observation of phenomena from the rapid expansion of the universe known as the inflationary period.
