I need to throw a few things out here, I'll keep things simple and expand later.

On time travel:
We know that differential calculus is the rate of change over time, whether that change is temperature, distance, amplitude, whatever. We also know that the speed of light is ~186,000 miles per second, fast enough to circle the earth ~7.5 times in one second.

Now, suppose I were traveling in my spaceship from New York to Los Angeles, a 3000 mile journey. My first run, I mosey along at 1000 miles per hour, the trip would take 3 hours. If I were traveling at 3000 MPH, it would take 1 hour. If I keep increasing my speed, I could get there in one minute, increase the speed further and I could get there in one second.

If I keep increasing my speed, I could cover the distance in one tenth of a second, then .01 second, then .001 second. As we can see, Einstein was correct, as you approach the speed of light, your mass increases exponentially. What is happening is that in order to move that decimal point another position, you need to increase your power exponentially just to get another incremental gain.

At what speed will I make that journey in Zero seconds? The answer is that you can't. Even if you make the journey at .000000001 seconds, much faster than the speed of light, your are still traveling a distance. Distance is still the rate of change. You cannot travel so fast that the rate of change becomes time itself.
