Is every bit of information (anything) in the Universe have mass? Also, light has to have mass because it is affected by gravity, correct? Last question, What is "space", not just outer-space but also the space we "live" in, made of? Is it filled with an infinite(or really big amount) amount of atoms? So, if this where true you could say that the Universe is just filled with an infinite (or really big amount) amount of atoms that make up everything... Sorry, I really like Physics but just have so many questions.
