- 02:03: Along with Boris Podolsky and Nathen Rosen, he proposed the EPR paradox which was meant to deal a swift death-blow to this observer-centric nonsense.
- 02:13: We’ve talked about the EPR paradox before, but it’s really worth a second look - especially given the stakes.
- 03:36: Standard quantum mechanics says that this is possible, but it leads to the seemingly absurd result of the EPR paradox.
- 05:24: The EPR paradox was meant to show that this sort of undefinedness couldn’t be the underlying reality because it violated the cosmic speed limit.
- 06:25: It wasn't until 1960, nearly 30 years after the EPR paradox paper was published, that physicist John Bell gave us a concrete test for all of this.

2021-11-17: Are Black Holes Actually Fuzzballs?
- 00:02: Black holes are a paradox.
- 00:04: They are paradoxical because they simultaneously must exist but can’t, and so they break physics as we know it.
- 01:08: There’s our first paradox.
- 01:10: And at the event horizon another paradox arises.
- 03:40: This threat of erasure of quantum information in a hairless black hole is the black hole information paradox.

- 04:07: While we’ve covered these black hole paradoxes before, and have even hinted at possible solutions - we’ve never actually solved them.
- 04:17: Ultimately, the black hole paradoxes stem from the disagreement between quantum mechanics and general relativity.
- 05:28: Black hole paradoxes may be solved by string theory.
