You're on to something, I suppose, but the conservation of momentum does allow for travel in a vacuum. The matter ejected by the thruster pushes against the rocket.

They're not on to anything here. As further stated by your comment.

It could be tested to a degree with a vacuum chamber here on earth. Put a little rocket inside horizontally and see if it moves when fired in a partial vacuum.

It might surprise you, but there have been numerous tests in vacuums on earth.

Also numerous tests in space.

Yup. You'd also have to discount satellites as fake if you choose to not believe in rockets. And also everything that satellites provide for us.

Plus, you know... basic physics.

Pff gps is a hoax, in reality there is a little goblin with a perfect sense of direction in your phone.

GPS: Goblin's Perfect Sense (but in the phone)

Yes I agree with you in that it would have the undisturbed momentum from pushing off from earth. But no way to slow down, or change course. I'm not sure mater ejected could push back. Surly the vacuum of space would just suck the rocket or thruster empty as fast as possible. . It just bugs me. Lol
