Sort of, but gravitational lensing has been seen in places where there is no visible matter. If dark matter doesn't exist, then you'd have to come up with another explanation for the gravitation lensing:

- Beldin 4y agoYou're absolutely right and this is the one thing about dark mayer that doesn't sound like "just keep sprinkling it on your problem till it works." I don't know enough about the found examples of gravitational lensing to know whether all possible arrangements of black holes that could have the same effect, have been considered and found lacking. But I presume so.
