Yes, and it is a very nice experiment.

However, "dark matter" is an admittedly lose framework it could be due to 1 new type of particles, 10, or higher dimensional effects and new physics we don't understand yet. Saying "therefore it doesn't exist" is ignoring the mountain of decades old solid data showing gaps in our knowledge exist.

And as for dark energy... "The universal expansion is accelerating". Well done you now know as much as 99% of the physicists in the world on this strange unexplained problem.

We consider particles with oscillatory behaviour sufficiently different from aether to abandon the name and the concept as useless. But contrary to aether, dark matter is still a new, vague and complicated concept: there is ample room to evolve dark matter theories without giving up on the idea of dark matter.

In any case competing theories will need to converge towards new experimental evidence and therefore towards each other, and then names and starting principles will be unimportant.
