BTW: One of the big reasons folks are interested in Gravity (waves,
quanta) is to study the early universe in much greater detail.
The Cosmic Background Radiation is of photons, which were not
"liberated" by the early environment for something like 100,000
years. Neutrinos offer a much shorter threshold in terms of years,
but gravity waves would be completely unhindered.
The various satellite and ground-based gravity wave observational
sites promise interesting information within 10 or so years, some
much sooner.
