Which brings me back to my original post. To time travel you would have to, in part, remove yourself from all gravitational forces. By not doing that you'll be staying where the Earth is at that period of time. For instance the position of the Earth 100 years ago compared to it's current location. Works out to be around 2.8 trillion km over only a 100 year period. That's a big problem.
Time and space are the same thing, it's a fabric. Even walking to your refrigerator is traversing the fabric of space time and you are technically time travelling. Some would argue, that everything exists simultaneously in a multiverse and that time travelling is just creating yourself a reality in another multiverse. But not creation in the way that you'd plan it out to be.
