How to give a spacecraft a translation motion at constant mass.

Abstract

When you fire a bullet the gun experiences a backward displacement that can be stopped when the fired bullet hits an attachment to the gun beyond the muzzle. At the end you have the entire gun system being displaced through space at a constant mass. This is best done using an electric gun that does not consume gun powder. I have written this basing on experiments I have personally carried out.

Your ideas are welcome.

Do you really think that it were as simple as that to move a spacecraft in space that nobody else would have already thought of it and it wouldn't already be in use?

 

The simple fact is that it will not work like you think it will. The whole apparatus will just vibrate back and forth around the same point.

 

Sure, you might get it to move over a surface like the ice you mention, but that it just taking advantage of the difference between the static and kinetic friction between the apparatus and the ice.

Because of the this difference, it take a bit more force to get something sliding on the ice than it takes to keep something already sliding to keep sliding. Thus if you generate a fast jerk in one direction, and then a gentler motion in the other, you can get a net motion over the ice.

But in space you have no friction to take advantage of and you get no net motion.

If ever I want to go to the moon I'll just tug on my boot laces. I'm not quite strong enough to take off yet, but if I was actually on the moon I could take off no problem. I can easily handle 1/6 of my weight.

Worth noting that in curved space-time it is possible to "swim" through empty space: http://dspace.mit.edu/handle/1721.1/6706
