A hypothesis has to be tested by observations and experiments.
Place a big, metal ball in a room that is kept at a constante temperature. Measure the temperature in the middle and in the border of the ball.
Place two thick walls of equal size at a small distance from each other. Hang a plate of lead, connected at two long threads, between the walls, in the middle. An iron plate may have a magnetic effect. The classic gravitytheory tells that the plate will stay at its place. The same for the hypothesis. Move the walls so that one wall is close to the plate. The classic gravitytheory tells that the plate is most attracted by the closest wall and will move to this wall over a small distance. According to the hypothesis there is in this situation no gravityforce on the plate from the walls and the plate will stay at its place.
In 2017, in Australia, in a barn, I had a selfbuilt apparatus of wood, lead, an iron thread, thin rope and newspapersheets. I wanted to carry out an almost same experiment. CERN is not at my disposition. The trial was a failure. The forces were too weak to measure.
