> But over the years, cosmology entered an age of precision. We got details from the cosmic microwave background that told us a lot about the Universe's structure and evolution. And suddenly we could calculate how the Universe would look like without dark matter. It didn't look much like the one we observe today. This new line of evidence, was, I think, the factor that has driven many physicists to accept dark matter as a reality.

But MOND theories, which are supposed to do away with the need for dark matter, have been in a similar position—they can't explain both of these observations, either.
