>and the the problem is that even if you are moving at near the speed of light away from the opposite direction of light, when you measure it, it will still be the constant. If you are standing still it is still the constant. So while it seems that you could add the two opposite velocity vectors, you cant, because when you start moving, the speed of light remains constant in all frames.
...*sigh* by that logic E = mc^2 shouldn’t EVER work because there is no way to alter/manipulate [anything involving] a “c term” so that you can get a “c squared.”
You know there is a book, seriously, not trying to dismiss your questions, called “Einstein for dummies”, that you can probably find at your local library. I already said I am somewhat at my limit of explaining the discoveries of perhaps the most gifted man in history. I wont waste any of my life trying to dispute something Einstein said. I think I would ultimately lose that battle.
E = mc^2 is about matter energy coversion. Its a ratio. Its separate from the physical limitation of the velocities of matter.
