The basis of time travel is the Flux Capacitor. This is the only way to generate a rift in the space time continuum. When this is created your motion through space will change in relation to time and then enable time travel. To power a Flux Capacitor it requires 1.21 gigawatts of electricity. This is equivalent to a bolt of lightning or 5,601,852 car batteries. I am in the process of installing a Flux Capacitor in my Iroc-Z Camaro. Right after I fix the power trunk. Anyways, a good vehicle is neccesary when dealing with time travel. In order to manipulate the space time continuum you must be moving at a speed of roughly 88mph. This in combination with the 1.21 gigawatts of electricity powering the flux capacitor will create a rift in the space time continuum. Thus motion in space will now correspond differently with time. In order to control this you must also install time circuts into you DeLorean, Camaro, or other vehicle of choice. This will enable you to derive formulas predicting the new space time relation and program them to use in an easy dial up format. Unlike in Bill and Ted's excellent adventure you will not need an antenna to use this feature. So now that you know how to travel through time I bid you farwell and good traveling. But as a warning I suggest that you bring a picture of you and a few friends as a measure of status in time. If any of you start to disappear in the picture it means that you are threatening your existence and that you have to return to the present immediately. Well, with that said I wish you all good luck.
