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.

Its a bit like what you see in a cartoon the coyote has been pushed of the cliff standing on a rock why doesn't he just wait till the last second a step off rock, it wont help he is falling due to gravity at the speed of the rock.

Well your rocket would effectively be dragged along with everything else so nothing would be gained.

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?...Nothing?

edit on 22-3-2012 by blocula because: (no reason given)

Think of a really powerful gun when you fire it the bullet small mass high velocity forces you back the larger mass at a lower velocity.

The fuel being burnt up by the rocket is like a constant stream of bullets leaving the gun, now I think you should google Newtons Laws of Motion!

the thing is blocula, it's all relative.

to us the Universe and galaxies are extremely large, but to something else they could be mere specks moving across an infinite plane.

so the speed wouldn't mean anything at that size comparison.

and microscopically everything is moving even faster, so fast it gives an illusion of stability.

We really don't need you to introduce a different subject that you seem to be displaying ignorance in. You should keep that crap where it belongs. Hit and run post's are cowardice.

LOL that was just a friendly dig at ProudBird, please you have no reason to involve yourself. Stay on topic eh?

Nothing ignorant about it, equal and opposite reaction is a very important law in all classical mechanics, and is commonly misunderstood.

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?

it is accepted because it is fact. It was determined this by questioning...

What, exactly, would blow the clouds away? The whole atmosphere is held in place by gravity and is protected from being scoured by the solar wind by Earth's magnetic field.

Simple science...

The voyager and discovery deep space probes are moving outwards at around 38,000 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 attain and maintain that velocity in a frictionless void,the airless vacum of outer space,when there was and is nothing behind them to propel themselves off of to be able to have reached and still keep moving at that speed?

They can maintain their speed precisely because they are in a vacuum and there is no resistance. How they got to that speed is down to constant acceleration assisted by gravitational slingshots.

All this stuff is out there for you to read matey, this is really basic, entry level science....

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...

A jet a rocket operate in entirely different ways. Again, simple stuff that you could learn about in 5 minutes, but clearly can't be arsed. A Jet engine sucks in the surrounding air, heats it and the resulting expansion of hot gases out the rear of the engine pushes the craft forward.

A rocket has it's own oxygen supply on board for the fuel, so does not need at atmosphere to operate in. Same principle, hot gases expelled from the rear propel the craft forward.

really, really, really basic physics that most people learn when they are 12.

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...

HAHAHA, it is verifiable my friend with a basic understanding of science.

If you don't believe it, what do you think is going on? I need a laugh..
