2022-12-08: How Are Quasiparticles Different From Particles?

  • 13:28: ... are magnons - quanta of waves in that lattice, or skyrmions, which are localized, stable topological field configurations sort of like knots - all very ...

2022-03-30: Could The Universe Be Inside A Black Hole?

  • 06:35: But there’s still an “outside” in which the white hole appears as a bright, localized point in space.

2022-01-27: How Does Gravity Escape A Black Hole?

  • 07:02: Virtual particles aren’t localized like that.

2018-09-20: Quantum Gravity and the Hardest Problem in Physics

  • 11:09: The non-renormalizability of quantized general relativity is connected to the idea that precisely localized particles produce black holes.

2018-03-15: Hawking Radiation

  • 08:47: Firstly, this radiation is not localized.

2018-01-17: Horizon Radiation

  • 04:35: A particle perfectly localized in space-- a single spring or a single point on the drum skin.
  • 05:56: So let's take our spatial quantum field-- our drum skin, with its single, localized particle, and transform to momentum space.
  • 06:13: ... in momentum space, that single, perfectly localized position oscillation can also be described as an infinite number of ...
  • 05:56: So let's take our spatial quantum field-- our drum skin, with its single, localized particle, and transform to momentum space.
  • 06:13: ... in momentum space, that single, perfectly localized position oscillation can also be described as an infinite number of unlocalized ...

2017-12-06: Understanding the Uncertainty Principle with Quantum Fourier Series

  • 08:38: So if we measure a particle's position, then from our point of view, it's wave function is highly localized in space.
  • 10:26: ... a single particle, a quantum field vibration, perfectly localized at one spot in space, can so be described as infinite oscillations in ...
  • 10:51: So a perfectly specially localized particle is equally an infinite number of momentum particles that themselves occupy all locations in the universe.

2017-04-26: Are You a Boltzmann Brain?

  • 03:37: For example, tiny, localized dips in entropy happen all the time, when you get a chance convergence of a few particles in one corner of the room.

2015-09-23: Does Dark Matter BREAK Physics?

  • 09:36: In fact, in the vicinity of the black hole, this radiation is poorly localized, having a wavelength of all of the Schwarzschild radius.

2015-04-29: What's the Most Realistic Artificial Gravity in Sci-Fi?

  • 00:58: There's simply no known way to produce the equivalent of 1 Earth g on stacked, flat surfaces, like decks of a ship, in any localized region of space.
