DUDES, just had a crazy thought.
let's say you got a fuckin time machine that functions perfectly, it moves you forward or backward in time however far you want. let's say i went a year into the future, wouldn't the time machine stay in place? meaning, when i skipped a year forward, the earth/sun/everything that exists would be in a different position than it is now relative to where it was when i started my time travel.
so a time travel machine HAS to also teleport you in space to a very specific point in the universe if you want to end up on land and not in the vacuum.
Good point, if the Delorean doesn't include itself in the travelling how could one get back to one's original time. Truly, how could one travel from moment (now) to moment (n) if ones time machine couldn't move from moment (now) to moment (n)? If we view time (the fourth dimension) as a point, we can view it as a value, or a function that can be resolved as a value. If we examine that function through a value (x) we can interpret it as a place within that function, if we examine the same function through a different value (y) we can interpret the function at a different point. We can then ask, does this function exist at both value x and value y? If we view time (the fourth dimension) as a function that changes when x (the value we choose to interpret it by) changes, we see that the function exists as it is at each value we choose to evaluate it by [x, y, z]. The function exists AS IT IS in all of these states, these states change as we move through the function (the function x squared exists at x=3 as 8, and at x= 5 as 25). We can view time travel in the same way, as a function. Our perception of the universe changes as we move from 2009 to 2012 (in the same way we evaluate x squared for different values of x) but the but the universe as it exists in 2009 does not change when we evaluate it, even if we have traveled from another time (value of x).
Please object where you differ.
