FactChecker reacted to A.T.'s post in the thread Undergrad How does reciprocal time dilation work? with
Like.
Because that's how the Lorentz Transformation works. -
FactChecker replied to the thread Undergrad How does reciprocal time dilation work?.Any IRF can be considered to be "stationary". So either one of the clocks in their respective IRF can be "stationary". It is not about...

Additional to @Dale's comments, you also assume that they zeroed their clocks when they passed one another. And you are talking about...

FactChecker replied to the thread Undergrad How does reciprocal time dilation work?.The clocks are traveling long distances in opposite relative directions to each other. The ticking rate of a traveling clock is most...

Skeptical.
I wanted to respond with a laughing emoji but that would be unfair. After all, highschool is where you make your choices regarding your... -

FactChecker reacted to PeterDonis's post in the thread Undergrad Photons vs Gravitons with
Informative.
Classically, fhe field equations for light and gravity are similar, yes; both of them have the basic form of a differential equation... -
FactChecker reacted to Ben vdP's post in the thread High School Why simplifying this function generates different outputs for same input? with Like.
As already mentioned in other posts the first function is not defined for the value 2. So they aren't entirely the same functions. But...
