Hi. 4 years ago my child asked to me a question... What will be happen, if the light is stop? I tried to answer it ... But my knowledge is insufficient. (I had been educated at social science, specially labor laws) . So I searched, tried to learn something new... So I liked physics. Of course it is only a hobby for me... I'm still far from terminology of physics. Also i generally read in my native language. But i made some assumptions and they seem to me probably logical. I wrote them at my blog page. I think with my questions, you may guide me.
