- 11:49: ... inertial observer sees that there's a type of friction between the accelerating observer and the quantum field which should inhibit that acceleration by creating ...
- 11:59: But the accelerating observer doesn't directly see that friction.
- 12:05: The answer is that the accelerating observer perceives themselves to be plowing through a bath of Unruh particles, and these produce the drag.
- 12:13: The accelerating observer must expend more energy to produce the same acceleration.
- 11:59: But the accelerating observer doesn't directly see that friction.
- 12:05: The answer is that the accelerating observer perceives themselves to be plowing through a bath of Unruh particles, and these produce the drag.
- 10:57: Last week, we talked about the mysterious Unruh effect, in which accelerating observers find themselves bathed in a sea of particles.

2018-04-04: The Unruh Effect
- 04:50: This means that any events happening to the left of that diagonal line will never affect the accelerating observer, which sounds pretty horizon-like.
- 05:06: ... named after the coordinate system we use to describe a constantly accelerating observer in special relativity, Rindler coordinates, devised by Austrian ...
- 05:20: The Rindler horizon flows at a fixed distance behind a constantly accelerating observer.
- 01:14: It tells us that accelerating observers find themselves in a warm bath of particles.
