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. Schilling interviews both believers and heretics and paints a colorful picture of the history and current status of dark matter research, with astronomers and physicists alike trying to make sense of theory and observation.

| 0:06.0 | We know that excellence takes time. |
| 0:09.0 | So you can rely on the Honda engineering in the all-new ENY-1, |
| 0:13.0 | with a range of up to 250 miles on a single charge, |

| 0:26.0 | Yes. |
| 0:27.0 | Honda, the power of dreams, range based on test conditions, and they vary. |

| 0:37.0 | I'm John Batcha with Gov. |
| 0:38.0 | Chile, his wonderful new book, The Elephant in the Universe, |
| 0:41.0 | 100-year search for dark matter. |
| 0:43.0 | It also has travels and his conversations with astronomers and researchers |
| 0:49.0 | in deep minds in the beautiful chili, high desert of chili, |
| 0:54.0 | and also back in time, Gov is going to take us to the big bang, |
| 0:59.0 | and why it is that that's important to make part of the search for dark matter. |
| 1:05.0 | What happened in the first moments? |
| 1:07.0 | How can we imagine it, Gov? |
| 1:09.0 | It's an extremely complicated topic, but we see now that space is expanding |
| 1:14.0 | because all the galaxies get farther and farther away from each other. |
| 1:18.0 | So the empty space between galaxies is expanding. |
