Im sure 'rocket scientists' have thought about this.
Maybe we could use the speed of everything else to our advantage when intersteler traveling.
Maybe we could just let the other stars come to us, kinda thing. Or propel our rockets in the opsite direction of galaxy travel and use the combined speed of the rocket with the speed of the approaching intersteler body.
Dunno, just a thought.
Then how are spaceships able to propel themselves forward in a frictionless vacum,what are their rockets pushing against that allows them to move outwards once their in outer space?

Blown away by what?
By the fact that we,the earth,the whole solar system and the entire galaxy are all supposedly flying outwards through the universe at the almost incomprehensibly mind numbing speed of 2,237,000 mph,thats what and yet those fluffy white clouds up there in the sky are able to resist and withstand those incredibly fast speeds and not be blown out of the atmosphere and into outer space.How is that even possible and why is that just accepted as being truth and fact without question?

Whenever i've thrown a large bowling ball,or heavy rock,or whatever,i always feel myself moving in the same direction i'm throwing them,not away from them and so in a frictionless void,what exactly is a rocketship propeling itself forward from? Nothing? I can propel myself up by pushing myself off the floor,but once a rocketship is in outer space,theres nothing behind it to propel itself off of and move forward,just an empty, frictionless void and so where exactly is its forward momentum originating from? Nothing?

The voyager and discovery deep space probes are moving outwards at around 30,000 mph and they have been for a long time now.But,they obviously didnt leave the earths surface at those fantastic speeds and they didnt leave the earths atmosphere at those fantastic speeds either and so how were they able to reach,attain and keep that velocity in a frictionless void,the airless vacum of outer space,when theres nothing behind them to propel themselves off of?
Theres no sound in space,theres no air in space,theres no atmosphere in space and so how a jet or rocket operates and flys here in earths atmosphere,would not work at all the same way in outerspace...

You know a jet engine doesn't propel itself and it's craft against the air, it accelerates the air it sucks in and propels the thrust against itself. Here's an experiment you may be able to do, get a bazooka, jump up or off of a safe distance and fire the thing when you are not touching the ground, and you will be blown the opposite direction as the projectile.
You are using your bodily motion to propel that bowling ball that is greater than the force of the bowling ball, unless you weigh about 9 pounds.

Ultimately,the tiny minority of they,are telling the huge majority of us,that the earth is traveling outwards at 2,237,000 mph and i'm suppose to actually believe that? I dont...
