Hello, I am new here but I am starting regain an interest for sciences and I have come here hoping to improve my understanding and knowledge. I admit, I don’t know a lot but I was hoping by being here that some of you could teach me and change that, if that’s okay. I might be taking a few science class in college and I like to get a head start by learn about a big chunk the subjects before I even start the class’s. So my first question is can some explain to me what the theory of relativity is and how it works to some one has no understanding of it?
