Time travel

Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically using a hypothetical device known as a time machine. Time travel is a widely-recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine.

The Grandfather paradox is a very intriguing paradox that goes as such: The time traveller went back in time to the time when his grandfather had not married yet. At that time, the time traveller kills his grandfather, and therefore, the time traveller is never born when he was meant to be. If he is never born, then he is unable to travel through time and kill his grandfather, which means he would be born, and so on (Wikipedia). So is this just a infinite time loop that never seems to stop? Is the time traveller stuck there or what? I find time travel extremely interesting and wonder if it is ever truly possible. My point of view on this is that we are currently living in the present: now. By the time you read "now", it is already in the past and you can never go back to that certain point where you first read that word. As time goes on, the previous moment vanishes forever and we only exist in the "now". So I was wondering how can time travel happen? There are many other ways to view time; as a straight time line or many timelines that branch off of just one single timeline. What I mean by that is what if there are other timelines that exist beyond the one that you are in right now? For example, If made a decision this morning whether to go to class or not. Surely you chose to go to class because you want to pass the class and get those credits for your major or whatever. But maybe there is another timeline where the opposite has happened an it exists simultaneously. I have so many other time travel questions that are hard to explain in words and can only be understood if you were to read my mind. Is time travel only possible to the past or the future as well? What if you time traveled 5 years into the future but realized you were already dead? Would you just die if you skipped your whole life period or would the past version of you simply still be alive just in another timeline that somehow merged with the one where you died. Wow, just let me know about your thoughts on time travel and questions, I'm so curious to know.
