Sabine | Gravity Without Mass Could Explain Dark Matter

I recently read that you can have gravity without mass. Ha, no way, I thought and had a look at the paper. It's wild, people.

The author says that there are hollow spheres scattered across the universe that have no gravitational attraction and that these spheres explain dark matter. I will try to sort it out for you.
