2021-03-09: How Does Gravity Affect Light?

  • 05:36: But for that to be the case, light must travel a curved path from the point of view of the accelerating frame.

2021-02-10: How Does Gravity Warp the Flow of Time?

  • 05:52: It tells us that whatever we conclude about the passage of time in an accelerating frame must also be true in a gravitational field.
  • 06:00: To get an accelerating frame we could strap rockets to our gerdankenlab - and don’t worry, we will.
  • 08:43: But overall, the distance for a single up-down tick is larger in a linearly accelerating frame compared to the inertial frame.
  • 09:25: ... can calculate the difference of the flow of time between an inertial and accelerating frame using pure special relativity with its kinematic time dilation plus ...

2018-04-04: The Unruh Effect

  • 06:20: ... also lead to a mixing of positive and negative frequency modes in the accelerating frame of reference, which leads to the creation of particles in that ...

2016-01-13: When Time Breaks Down

  • 05:07: The overall distance that the photon has to travel is larger in an accelerating frame.
  • 05:20: But Einstein's equivalence principle tells us that a frame suspended in a gravitational field is indistinguishable from an accelerating frame.
