The dark energy that's accelerating the earth seems to push it along like wind in a sail. It has been said that the earth's mass shields the dark energy and keeps everything on the earth in place so all you feel is the upward acceleration of the earth at your feet. Then it seems that the dark energy bends around the earth, recombines, and pushes on the sun and moon. The earth, sun, and moon must have some characteristic in common relative to the dark energy because the effects of the dark energy on all three bodies are the same. Otherwise, you would see with your bare eyes either the sun and moon crashing down to the earth, or departing slowly to parts unknown. You could hypothesize that the sun, moon, and earth all have the same mass, and it's the mass of a body that determines how much push it receives from the dark energy. That would mean that all the bodies would have to have different densities and all those densities would have to be exactly right for the system to work. You can see that the area just won't work at all. Then you have to conservation of energy question. If the dark energy is pushing on the earth, it will be giving up energy and loose some of it's potential to push on the sun and moon. If you take a couple of magnets and turn them so they repel each other then you can push one along with the other. However you will have to be providing a force with the one magnet. What is the dark energy pushing against on the other side? Any action will produce and equal and opposite reaction. Maybe that law will have to be thrown out as well. Also the sun seems to change orbits in the different seasons. If you want to change an orbit to a smaller one you will have to do two things. Number one is to provide a force on the outside of the moon to tighten up the orbit, and another, slow the sun down. A smaller circle will require a slower speed to keep the orbit time constant. Is the dark energy also providing all these services?
