The Physics of Time Travel

Time Travel in a Quantum Mechanical Universe. Time is mysterious. Philosophers and scientists have pondered the question of what time might be for centuries and yet till this day, we don't know what it is. Everyone talks about time; in fact, it's the most common nouns per the Oxford Dictionary. It's in everything from history to music to culture. Despite time's mysterious nature there are a lot of things that we can discuss in a logical manner. Time travel on the other hand is even more mysterious. It's a subject that captured the interests of great writers like H.G. Wells and Mark Twain and has been the premise of T.V. shows and movies. Everyone would love the idea of getting on Doc Brown's DeLorean and taking a blast to the past but it isn't as simple as science fiction would put it. In this work, I explore the nature of time and take a side on several fundamental questions about it. I then explore a model of time that I created based on my research which allows for the possibility of time travel. I don't believe that this model accurately models time (or is complete) but in my opinion, this would be the best model that avoids a lot of paradoxes of time travel assuming time travel is possible. Finally, I explore several paradoxes of time and explain how my model of time could solve them to a certain extent.
