Might the strong force have an effect on the gravitational waves zipping through the universe?

 A really interesting idea is being investigated by astronomers at LIGO, the famous experiment that detected gravitational waves, predicted by Einstein around 1915 and discovered by LIGO in 2015. Some early low-energy gravitational waves should have been produced in the fractions of a second after the Big Bang occurred. This is similar to the microwave background found everywhere in the universe. New techniques are being considered for trying to detect these incredibly low energy waves, which would have been generated during a phase where the strong nuclear force emerged from the Big Bang. More fascinating ideas to consider!
