Original sentence: Modern Trouton and Noble experiments have improved on the sensitivity of the original experiment, by using higher voltages and better controlled experimental conditions.Some experimenters claim that even if the aether exists as originally proposed, Trouton and Noble wouldn't have been able to detect it using their apparatus
Edited sentence: If the aether existed as proposed, Trouton and Noble may not have been able to detect it using their apparatus.It is generally thought today, Trouton and Noble wouldn't have been able to detect it using their apparatus.Modern Trouton and Noble experiments have improved on the sensitivity of the original experiment.The experiment has been repeated several times since, with higher voltages and better controlled conditions.These experiments have not repeatably indicated the existence of an aether
