| 0:00.0 | The long arc of physics bends towards what exactly? |
| 0:13.2 | Over the centuries we have developed theories to explain the universe and then seen them |
| 0:17.4 | overturned, replaced by something new. |
| 0:20.2 | Einstein's gravity replaces Newton. |
| 0:22.6 | Quantum mechanics upends a deterministic universe. |
| 0:25.5 | It feels like progress, but is it? |
| 0:27.9 | We imagine that there is a single beautiful, simple set of laws that control how the universe |
| 0:33.2 | works and that with each new idea we are getting closer to the deep truth. |
| 0:38.3 | But what if there is no single deep truth? |
| 0:41.8 | And what is it that we are learning anyway? |
| 1:00.0 | Hi I'm Daniel, I'm a particle physicist and a professor at UC Irvine and I'm spending |
| 1:05.1 | my life chasing the truth of the universe. |
| 1:08.4 | And welcome to the podcast Daniel and Jorge explained the universe, a production of |
