How the Universe Unfolded

An article in the Herald Globe tracks research being done to unravel the mystery of how the universe began. The author writes:
The research was conducted by a team of scientists associated with the LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration and the Virgo Collaboration.
The new measurements by LIGO directly probe the gravitational wave background in the first minute of its existence, at time scales much shorter than accessible by the cosmic microwave background.

"Our results are a major step toward the detection of primordial gravitational waves - ripples in the fabric of space and time - that were created as the universe expanded in its earliest moments," said Lee Samuel Finn, a Penn State professor of physics and of astronomy and astrophysics.

"This type of information would provide vital clues to understanding how the structure of the universe evolved. For example, why is our universe clumped into galaxies? This information also would tell us whether some of the fantastical proposals are correct about the way our universe came to be," he said.
I love research into the Big Bang. It is, for the most part, ideology-free.
