20220824: What Makes The Strong Force Strong?
 18:36: Those fields have positive and negative frequency modes that cancel each other out to leave a vacuum.


20220622: Is Interstellar Travel Impossible?
 19:30: Hawkingâ€™s original argument talked about perturbing the positive and negative frequency modes of the quantum vacuum.


20191007: Black Hole Harmonics
 03:34: Higher frequency modes are called overtones, and they provide richness and texture to the sound.


20180404: The Unruh Effect
 06:00: And just as with Hawking radiation, that horizon cuts off your access to certain fundamental frequency modes of the quantum vacuum.
 06:20: ... here they also lead to a mixing of positive and negative frequency modes in the accelerating frame of reference, which leads to the creation of ...


20180315: Hawking Radiation
 03:51: ... is in a vacuum state, there's a balance between positive and negative frequency modes, which you can crudely think of as a balance between virtual matter and ...
 08:13: So Hawking's math describes splitting or mixing of these pure positive and negative frequency modes.
 10:05: We can think about positive and negative frequency modes being mixed due to scattering, perhaps, by the as yet undiscovered graviton.


20171108: ZeroPoint Energy Demystified
 04:31: By cutting off certain frequency modes between the plates, you lower the vacuum energy in that region.
 08:35: ... field is estimated by integrating the energy in all possible frequency modes up to some cutoff ...


20171102: The Vacuum Catastrophe
 02:09: ... except to properly describe a perfect vacuum, every single possible frequency mode at every point in space must have that amount of ...
 02:23: To calculate the density of energy of the vacuum, we should add this tiny energy over an infinite range of frequency modes for all fields.
 02:59: Then our sum of frequency modes would be finite.
