2021-01-26: Is Dark Matter Made of Particles?

  • 02:05: Any electrically charged particle experiences the electromagnetic force and can communicate with other charged particles by exchanging photons.
  • 11:12: ... and antielectrons, or positrons, interact very strongly via the electromagnetic force - which means they find each other too ...

2020-11-04: Electroweak Theory and the Origin of the Fundamental Forces

  • 03:20: This was an early hint that somehow the electromagnetic force, which acts on charged particles, was playing a role here.

2018-10-03: How to Detect Extra Dimensions

2018-08-15: Quantum Theory's Most Incredible Prediction

  • 01:13: ... describe how this field interacts with charged particles to give us the electromagnetic force, which binds electrons to atoms, atoms to molecules, and therefore, you ...

2018-06-20: The Black Hole Information Paradox

  • 14:01: But quantum-field theory imagines the electromagnetic force as being transmitted by virtual photons.

2018-06-13: What Survives Inside A Black Hole?

  • 02:58: After all, the forces involved, namely the gravitational and electromagnetic forces, are only communicated at the speed of light.
  • 07:34: ... so the gravitational and electromagnetic forces have infinite range, and so Gauss's law demands that the mass and charge ...

2017-10-19: The Nature of Nothing

  • 04:33: For example, QFT describes the electromagnetic force as the exchange of virtual photons between charged particles.
  • 05:55: And so virtual photons can exist for any amount of time, long enough to carry the electromagnetic force to any distance.
