New to Relativity:Need Answers!
Hello guys,
It took me forever to become a member on here and get everything activated. Well I am new to SR and GR and I have more questions than answers. I read Michio Kaku's Book on Einstien. It was a really good book and I got some understanding of how Einstein became so great and why he had such a impact on the world of Physics. It seems that no matter how many times I read over the book and read websites trying to explain SR and GR I just don't get a few things. One thing that I have a hard time trying to understand is time dilation. I suck at math and don't understand any equations that someone throws at me. I really want to know why is it that time slows as you approach the speed of light without someone talking a lot of stuff I don't understand. What is the physical explination that can explain time dilation.
My other question is, what do you see if you were able to travel the speed of light. I remember in Kaku's book he talked about Einstein sitting in a cab and that he visualized what it would look like if the cab approached the speed of light. From what Einstein visualized that's when he had his big breakthrough with SR. Now I can't really understand how you still see something behind you, The Clock Tower that was mentioned in the book, when you are moving away from it at the speed of light.Also if you were an observer and you were watching someone speed off at the speed of light what would they look like, would they just disappear or would they become thin which is what i was lead to believe in the book.If someone can give me some easy explinations as to what I have asked or maybe some easy to read refrences on the net, note I have read a lot of websites on the net about SR and GR and no luck on understanding, than maybe I can get a clear understanding about what it all means. I have a deep obsession to find out what it would be like to see all this happening.
Thanks so much!
