Well, we do not have a time machine that could make us go to any time we want, I am sorry to disappoint you. What were you thinking anyway, it isn't even possible to travel back in time only forward at different speeds. One of these speeds we do every day on planet Earth, we are traveling in time constantly, constantly going forward. It is not my fault you have this mainstream idea whenever you hear time travel you think of a car that leaves two burning lines of fire on the ground and travels through time and sends us to the past!So you can't go back in time you said? Yes that was me, I said that. Let me explain, we go forward in time all day long, we even changed the pace on how fast we go forward in time ( more on that later ) but backwards just isn't possible. Lets say you are eating an apple, in this example the apple is time, you can eat your apple really quick or slowly but the apple becomes smaller and smaller whenever you take a bite out of it. You can't make the apple bigger by eating it, same goes with time, you can't go back to a former state ( for the sake of argument you are NOT about to vomit! )Are we able to manipulate how fast we travel forward then? Yes we can, yes we did it before, yes we are doing it right now. There are a number of possibilities to change the pace you travel at. If you are close to the speed of light you will travel faster through time than your surroundings, you could say you travel into the future at a more rapid pace than others. If you want to travel slower you could always stay close to an object with extreme mass, a black hole ( actually I wouldn't quite recommend this! ), or something closer to home, Earth.
