Alternate dimension slightly further ahead on their timeline their zero point energy vibration is slightly higher then ours therefore allowing them to penetrate our universe and perform feats that break our universes laws of physics because they can use energy from their own universe which vibrates higher then ours a battery in their universe would be a pulsar' maybe abit of exaggeration.

In ours, they can only move down in dimensions and to cannot return to their original dimension/ timeline therefore they keep running and trying to find technology that could help them in achieving it. They are scavengers and keep moving it's why they are all different because they are from different alternate futures where they make the same mistakes. It's like flipping a channel in a Infinity tv remote with little way of controlling the remote or returning to higher vibrational dimensions.

As they move further away from their original timeline/ dimension the weirder the choices and looks. We probably look strange to them as they do to us.
