Thank you Dale. I will likely be reaching out to Sabine and citing this thread, asking her to please correct her errors. I will be citing Dale the physics expert from physicsforums.com if that is OK with you--thank you:
You write, "She can state it because she is making a pop-sci video which has no peer review and so she can get away with saying whatever she feels like."
Do you believe that influential and popular public science educators have a duty to speak the truth and be correct?
Do you agree that mass curves both space and time? As a mass moves through spacetime, do you agree that the mass curves both space and time? Do you agree that as the mass passes a point, the space and time will curve in the vicinity of the point, and then, as the mass leaves the area, the space...
So then you disagree with Sabine Hossenfelder who says time dilation is due to acceleration in the twin's paradox, as she states in the video: "This is the real time dilation. It comes from acceleration."
Do gravity waves propagate through four dimensions, or only three dimensions? Do objects move through spacetime or only space? Do objects move only through space, but never through time? Are you saying all objects are stationary in time?
So then you disagree with Sabine Hossenfelder who says time dilation is due to acceleration in the twin's paradox, as she states in the video: "This is the real time dilation. It comes from acceleration."
So are you agreeing with Hossenfelder's statement that "This is the real time dilation. It comes from acceleration." What are the physical equations that show acceleration causes time dilation?
Interesting. Do physicists agree that a photon is a physical object? Do physicists agree that x4 is a physical dimension?
If so, what is the physical photon doing relative to the physical dimension x4? How is the physical photon moving relative to the physical dimension x4?
Sabine Hossenfelder says time dilation is due to acceleration in the twin's paradox. Is this true?
At 12 minutes into this video ,
Hossenfelder states, "This is the real time dilation. It comes from acceleration."
Looking at the equations for time dilation, time dilation comes from...
What is the velocity of a photon through the four dimensions?
What is the velocity of a photon through the three spatial dimensions x1, x2, x3?
What is the velocity of a photon through the fourth dimension x4?
