5. Headline: The MOND Heresy and Gravitational Lensing Guest Author:Govert Schilling Summary: Schilling introduces MOND, a "heretical" theory suggesting our understanding of gravityis flawed rather than matter being missing. While MOND explains galactic rotation perfectly, gravitational lensing allows scientists to map dark matter's distribution in space and time. Observations of the Bullet Clusterprovide strong evidence for dark matter, though MOND proponents still offer alternatives. (5)

| 1:02.7 | It's that puzzling. |
| 1:04.7 | So Govert has introduced us to the reasoning of what this particle might look like. They call it a WIMP, weakly interacting |
| 1:14.6 | massive particle. WIMP. However, the searches continue, and we're going to go to one of those |
| 1:21.0 | searches. But before we go there, Gover's surprises in his explication to introduce a chapter about a heretic. The man's name is |
| 1:30.3 | Milgram, and he and his colleagues are using Newtonian physics to explain what we |
| 1:37.7 | observe in the heavens. This is the part that I loved completely because this is not contrary. |
