It's not enough to be at the right space (=coordinates) at the right time, but you have to have both the right speed-vector and the right-acceleration vector, both compared to the universe (otherwise the milky way moves away from under your feet with galactic speed) and compared to your body (otherwise the speed/acceleration change will rip your body apart). And with right I mean 100% right, because we are talking about galactic speed and acceleration.
