Thank you all. Again, your responses were helpful. I have another question (about "tired light"), but I'm going to search the forum for similar questions before I go down that rabbit hole.
I understand that what you wrote in your first sentence is now the commonly-accepted position. Am I correct, though, that Einstein's position contradicted what is now the commonly-accepted position?
Thank you for your response. Your response to my questions regarding the photons was particularly helpful. With respect to your last paragraph, I was asking whether I was mistaken in thinking that Einstein's equations predict that the speed of light will vary as the light travels through...
ZapperZ: I think I understand what you're saying with respect to SR's equations not being meant to be used in a frame in which the speed of light is zero. Forgive my ignorance if I don't. Is there a particular speed at which the equations no longer apply/work? For example, if imagining myself...
Hello,
I am a father of three children (2 b, 1 g). My family and I grew up in and live in Michigan. I am an attorney, and my wife is a pediatric nurse. Despite standardized test results that suggest that I was and am quite intelligent, I essentially stopped trying in school in about third or...
When you say that "you cannot catch up light, never...you can never get to velocity 'c' locally," what does that mean? Does "you" refer only to human observers? If two photons are traveling next to each other in the same direction, and they approach and pass a photon traveling in the opposite...
