The total speed of an object through the dimension of space and the dimension of time equals the speed of light. An object moving through space must subtract from its movement through time for the sum to remain at lightspeed. So an object at the speed of light has all its movement through space and its movement through time must equal zero. Inversly a stationary object has all its movement through time and none through space. Making the quickest way to travel into the future is to stop moving. What parts of this quote need to be modified? The last sentence seems completely contrary to how I've understood "going into the future." Is this last sentence correct? The second sentence, when it uses the word "subtract", is what is hard for me to process. Can someone either modify this or explain it in finer detail? Is there a numeral that can represent one's movement through time? And can it be plugged into an equation that allows for it to be subtracted from or added to the "space numeral" so that the equation always equals the speed of light?
