Dark energy is not what we think.
The antigravity can be the "dark energy". That means the gravity wave's wavelength can change when it hits some other gravity wave or quantum field. If that wavelength changes the gravitational effect of that (gravity) wavelength ends. Is the wavelength transformation in gravity waves the reason for the effect called dark energy? Maybe gravity waves can transform into X-or gamma rays and that is the thing called dark energy or "antigravity". The term "antigravity" can mean a situation where a gravity wave's wavelength changes. If the gravitational- or gravity wave's wavelength changes. That means that. When a gravity wave's wavelength changes gravity wave is not a gravity wave anymore. So if a gravity wave can transform or stretch to the gamma- or X-ray that explains dark energy. The simplest way to think about that thing is that dark energy can be a gravitational wave that impacts something. And that turns the gravitational waves into...
