Will the force be with us?

Is there a fifth force to go along with gravity, electromagnetism and the strong and weak nuclear forces? Experimental work in Hungary in 2015 looking for dark photons has recently been revisited by theorists at UC Irvine. Their analysis favours an interpretation based not on particles or dark photons but on the presence of a fifth fundamental force. I trust that alternative conclusions based on the lawnmower conjecture have been considered and eliminated.
