In AWT the vacuum is the same stuff, like ordinary matter: dense fractal structure of space-time curvatures, simmilar to nested foam, formed by density fluctuations of hypothetical gas of immense density, so called an Aether.

Light waves are transversal waves of that foam, while gravitational waves are longitudinal waves. Photons are mixture of boths.
