I'm not sure if this is the correct place to post. I'm not in the field and have no scientific education beyond basic Calculus and Physics in high school and early college courses. I do ,however, find physics fascinating and spend a lot of my free time reading articles and watching documentaries on the subject. One thing I've always struggled with is the concept of time. The way I view time and the way I've heard it described by many physicists do not line up. I hear it described as being "real". Somewhat of a fourth dimension and something that is definitely a tangible part of the universe. I have a hard time grasping that. To my logic, time is an invention of man. It only exists because we have memory of events that have happened and the intelligence to know that more will happen, but that it isn't "real". There is no past, no future. Just different states. What happened yesterday is gone and doesn't exist in any form anymore. Excuse my ignorance as I don't have the knowledge nor the vocabulary to properly describe it, but I think I described enough to get my question across. Is there an analogy or a way someone could describe time to me in the way it is looked at in the physics field? I apologize if this isn't the place for these questions. Thank you.
