Few questions: When approaching c , why does time slow down? When travelling at c and time stops, how does light have time to reach a certain destination? What does a photon look like? Why doesn't it have mass, what are they made up of? Is there an equation for a photon? Does light bend because gravity is like a curve inwards on space 'fabric'? In the sun, what removes the electrons from the Hydrogen atoms for them to become Hydrogen Nuclei? Sorry for so many questions, I'm interested in physics (Sorry if they are basic questions, I'm only 14).
