Gravitational Waves in the Early Universe?

This thing is just in the planning stages. It's going to be orbiting the sun sort of with the Earth. The earliest targeted launch date is 2037, which is like comfortably far away enough that nobody has to like actually build anything today. If we build it, we will learn so much about gravitational waves, gravitational memory, gravitational background. Maybe also even see gravitational waves from the Big Bang - ripples in space that were created in the very, very early moments of the universe.
