Hello there, This is my first post on the forums, and I'm excited to be a part of this community full of science and mathematics! I do have a question, though. I understand the concepts and differences between linear and non-linear time, but I have a feeling that I might not be using the concept of linear time to interpret time. For example, when I'm doing something (it doesn't matter how big or small), I remember doing it, but I know I've never done it, and I know I've never done it. To back this up, I see myself standing in an exact position seeing someone's sweatshirt at an exact time when it happens. In a sense, I'm in the future and the present at the same time? If anyone could answer this question, that'd be amazing. Much appreciated, Gene
