Since the big bang, fewer galaxy clusters have formed over time than was actually expected. Physicists from the have now confirmed this phenomenon. For the next years the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories considered valid today need to be reworked.

This does not seem like a strong result yet:
“Our measurements confirm that the clusters formed too slowly,” said Dr. Pacaud. “We have estimated to which extent this result conflicts with the basic predictions of the standard model.” While there is a large discrepancy between the measurements and predictions, the statistical uncertainty in the present study is not yet tight enough to really put into question the theory. However, the researchers expect to obtain substantially more constraining results from the same project within the next three years. This will finally reveal whether the standard model needs to be revised.
Can our resident Physicists weigh in here? Thanks.
