When I first started reading up on physics I thought I understood it all, then someone told me that time is relative, and i went through a long process of disillusionment. After I thought I understood time being relative, I proceeded to develop a series of theories based on what I understood, and as far as logic was concerned, i was fine, but my foundations were or were not, depending on how you view the rest of this post. My physics teacher is great at teaching as far as my personal learning goes, but I'm not sure that he corrects me where I am mistaken and he has never told me that my theories were correct, rather he only states that my logic is solid. Then I had a similar conversation with my math teacher, and he said some things that shook my foundations a bit.
-Until today I believed;"Nothing can travel faster than the speed of light" meant that if something moved at the speed of light, and then was slowed down by the speed of light, it would be absolutely stationary. (c-c=0 and 0m/s being relative to the universe)
-This was where my confusion started, that the speed of light is completely and entirely relative (is it?); If an object is moving in a straight line at the speed of light, if you subtract the speed of light from it's velocity, is it absolutely stationary relative to the universe?(I realize that this question is fairly abstract because I didn't specify a point of reference for that object to be traveling by) I believed that there is a point at which you cannot accelerate any more (light speed), and if you stayed at that speed forever, you would never age, and you would never die. That was my understanding of the relativity of time and the relativity of the speed of light to an imaginary, stationary point. I'm very confused because of contradictory answers I have received to this question.
-If light always travels at the same speed in a vacuum, regardless of how fast the light source is traveling, then wouldn't it be subject to the Doppler effect? Is this the case? I'm very confused, please set me straight. Please post any valid, credible, and tested resources that I can read on the subject of relativity, my understanding has been shaken, and I'd really like to understand it all again.
Has it ever been proven that aging is relative? (twin paradox) That the effects and nature of time changes with speed? Is aging also relative to an observer?
My math teacher, in essence, said that the light travels relative to the source of light, that a light source traveling away faster the speed of light relative to an observer would not be seen by the observer because the light coming off of that light source would be traveling ((velocity of light source)-c) away from the observer and therefore the light would never reach the observer. and that is why nothing can travel faster than the speed of light relative to the observer because the observer would not see it. Is it true that the only acceptable truths in physics are those that can be seen? That is to say that if I establish that a flashlight is flying away from me in space faster than the speed of light relative to me, that if i cannot see the light from that flashlight, does it exist? Is observation everything, or can things be observed logically rather than physically? I'm very very confused, please correct any and all things that I've said incorrectly, and post any good resources. I'm shaking as I write this because I'm so insanely curious, I doubt this stress is healthy, please please please give me something to read, or concepts to grasp, and correct my misconceptions. Thank you
