But ten minutes ago the earth was there. That's the point I was trying to make with my statement. We don't have any machines yet that could push us in a negative space like direction. So how do we manipulate space? It appears to me that the academic community is doing everything in its power to make sure you don't find out.
Not sure what you mean by "the earth was there." If I'm driving down the highway and my body goes back ten minutes in time, there won't be a car under me because my car was ten minutes behind.
