INTRO: 10 years ago, the detection of gravitational waves from a pair of colliding black holes revolutionised astronomy. Now, a team of physicists from Europe are proposing a new theory of gravitational waves with the potential to disrupt one of the key ideas in modern cosmology. Theoretical physicists Daniele Bertacca and Raul Jimenez argue the cosmic inflation paradigm has too many free parameters, and we are expanding the limits of our theories to fit the data. Bertacca and Jimenez propose a radical alternative: gravitational waves and their dynamics were key to the early universe and ultimately gave rise to galaxies, stars, and planets... (MORE - details)
I tend to think of a more evolutionary approach as the models posed tend to imply a collection of already formed fields. Those fields from an evolutionary perspective are complex and will have required evolving to that point.

That would imply that something occurred before from a far simpler setup. (Such as diffusion of interlacing waves from a form of spherical symmetry which could lead to prototyping mass, which in turn leads to gravitation.)
