Aliens: Peaceful, Neutral, Hostile?

[Doc Velocity]

The laws of physics cannot be changed.

You don't have to "change" the laws of physics. Simply ignore them and they will go away. The laws of physics were invented by Man, and are therefore as fallible as everything else in the world of Man, including Religion and Science.

- how do you deal with friction from space debris, a force on your craft that is proportional to the velocity that you move?

Simple. Stop thinking of four-dimensional space travel as your only means of moving about the Universe.

- how do you deal with the fact that the faster an object is accelerated, the amount of energy required to move it faster increases with each increase in velocity the object makes

That's bullshit. No energy output is required to travel from one side of the fucking Universe to the other. The logical solution is to step outside of four-dimensional Space-Time and simply allow the other side of the Universe to come to you.

- how do store the vast amount of energy required to travel long distances quickly?

Again, you're living in some kind of Newtonian box that prohibits your free thinking. No energy output is required. Quite the opposite.

- how do you store supplies needed for long term survival away from resource centers like the original planet?

Easy. Don't send passengers who require food, water or air for survival.
