Can dark energy be the fifth force? We know 4 fundamental forces (3 if you don't take gravity), electromagnetism, gravity, strong and weak nuclear force. So can Dark Energy be the fifth force. All we know about dark energy is that it accelerates the expanding universe and it works on larger scales. Not in solar systems, galaxies or galaxy clusters but further away. I don't know the math in it but take the other forces for example: -Strong Force dominates on small scales -Electromagnetic force is stronger at a bit bigger range then the Strong Force -Gravity is stronger then Electromagnetism on larger scales -Dark Energy could be stronger on even larger scales then Gravity Is this possible?
