Sorry I guess I should have clarified, but I think the other reply said it alright.

basically, if I move backwards in time, in my own spacetime, then my relative position in the universe would remain unchanged. hence Maybe I go back to where I was in time and relative to the universe(my parent's home 20 years back). the tardis can put you back in time and change where in that time you were.

This is all theoretical, but maybe hollywood isn't as far off as we think (even if they would have arrived there by chance and not logic)

Well since all cordninates are realative, and your relative position to earth is unchanging, wouldn't that mean that everything else moves around you while you and the earth stand still and go back in time?

Drop off this drone with a different drone. Then fly it out wherever the other drones couldn't get to.

I think the long setup kinda adds to how bad the joke is. I'm not sayong this comic was good, but the fact it was so bad you wrote a comment about it's many faults shows it sparked SOMETHING in you.

A better, yet still mediocre, comic would have done nothing to you.

Keep it up OP!
