...The farther out from the center you go the less effect gravity has so objects will seem to speed up....

I like your explanation. I think Dark Energy is like Phlogiston theory or the Philosophers Stone. A theory that many believed was true at the time but was later proved to be wrong.

I think Dark Energy is like Phlogiston theory or the Philosophers Stone. A theory that many believed was true at the time but was later proved to be wrong.

Classic Newtonian phyics work just fine here on earth and in our meager solar system, but the model fails spectacularly for big stuff: galaxies, galaxy clusters, and expansion of the universe. Cosmologists introduced "dark matter" and "dark energy" as a fudge factor to describe physics that shouldn't be happening according to Newton. We currently have no explanation for these discrepancies.

A Nobel Prize and a million dollars is waiting for you if you can sort this out.
