4/8: The Elephant in the Universe: Our Hundred-Year Search for Dark Matter Hardcover – May 31, 2022 by Govert Schilling (Author), Avi Loeb (Foreword)
https://www.amazon.com/Elephant-Universe-Hundred-Year-Search-Matter/dp/0674248996
In The Elephant in the Universe, Govert Schilling explores the fascinating history of the search for dark matter. Evidence for its existence comes from a wealth of astronomical observations. Theories and computer simulations of the evolution of the universe are also suggestive: they can be reconciled with astronomical measurements only if dark matter is a dominant component of nature. Physicists have devised huge, sensitive instruments to search for dark matter, which may be unlike anything else in the cosmos―some unknown elementary particle. Yet so far dark matter has escaped every experiment. Indeed, dark matter is so elusive that some scientists are beginning to suspect there might be something wrong with our theories about gravity or with the current paradigms of cosmology

| 0:00.0 | This is CBSI in the World. I'm John Batch with Gov. Shilling. His new book is The Elephant |
| 0:10.5 | in the Universe, 100 years search for dark matter and Gov. search over several years |
| 0:15.7 | for dark matter. He's still looking. It's a joy to travel along with him in the book. |
| 0:20.9 | We know it, neutrinos don't qualify, although it's a cool idea because it took him a long |
| 0:25.6 | time to find neutrinos. And they had a theory and they went looking for it and it paid off. |
| 0:32.1 | Gravitinos also don't satisfy. And rather than pursue that, I'm going to come to the |
| 0:39.0 | cosmologist Jim Peoples. Jim Peoples says we have something that is cold, that is dark, |
| 0:47.0 | that is matter, cold, dark matter. However, it has to satisfy a transformation from the |
| 0:54.4 | smoothness of the beginning of the big bang to the clumps we have today. That means dark matter |
| 1:02.8 | has to satisfy something. Well, calling it weird is inadequate. It has to satisfy something |
| 1:09.2 | where it, what is it interact with in that transformation? What do we imagine does it have |
| 1:15.2 | interaction with anything in our standard model? Well, actually not much. We know dark matter |
| 1:24.8 | or the cold dark matter is Jim Peoples calls it, must be interacting through gravity because |
| 1:30.2 | that's how we discovered it. We see the gravitational effects. It must have mass, it must have |
| 1:35.8 | gravity. Otherwise, it doesn't fit in what we are observing. But it doesn't have an electrical |
| 1:43.4 | charge. So it doesn't interact with light. It doesn't interact with magnetism. It doesn't |
| 1:49.5 | interact with radiation. It doesn't interact with all the charged particles. It does not interact |
| 1:55.2 | with the strong nuclear force that holds atomic nuclei together. So the only thing that we think |
| 2:02.3 | might be possible is every now and then a particle might bump into an atomic nucleus and transfer |
| 2:09.5 | some of its energy to it just by bumping into it. But that's the only thing and that's a very rare |
| 2:15.1 | encounter. And that's the weak nuclear force. That's not the strong nuclear force. This is not, |
| 2:22.3 | as you say several times, this is losing its elegance. We're wondering into territory where |
