So I was doing some studying and got a question on why the rate of expansion of the universe was increasing, and it got me thinking.
Newton's first law states that an object in motion will remain in motion with a constant speed unless an external force acts upon it. If the expansion of the universe is increasing, does this mean that there is an external force contributing to this acceleration? And to maintain this force, work would have to be done to maintain acceleration, so where is this extra energy coming from? If the energy was finite, stemming from the big bang, surely the acceleration would be slowing down due to the energy being used up?
What am I missing? I'm pretty sure there is something I don't know yet, still in high school haha, so could someone help me out here?
