the gravity moves the Earth in a circle
Yes.
yes
The Earth moves around the sun due to the warping of space time that we perceive as gravity.
they are pulled by the Earths gravity
well space is like a vacuum you cant escape it and sound wave do not travel in space but space isn't literally a vacuum so they move by rockets and the gravity of earth
Earth has gravity so less fuel is needed to move a rocket in space(assume that you mean escape from earth's gravitational field by"from earth")
No I don't think so.
It moves in Time, the fourth dimension.
the gravitational pull of the earth moves the moon
Yes, you are not in space so you are still in Earth's gravitational force.
The less a star appears to move, the farther it is from Earth. Stars that do not appear to move are very far away from Earth, making their apparent motion negligible from our perspective due to the vast distances involved in space.
Radio waves travel with the highest speed in vacuum, and slightly slower in air. So they move slightly faster in space than on earth.
