Yes, everything in space is moving because there is nothing that fixes them to anything else. They are all drifting around with their own velocities.
The 'fixed' stars only look fixed because they are very far away but if you came back in 100,000 years the constellations would look different.
Stars all appear to revolve around the sky each day as the Earth revolves, but relative to each other the stars stay 'fixed'. That is because they are so distant it takes years for any of them to move appreciably.
Yes, all stars have a relative position and they al move within certain limits. Most stars move visually very slowly, so the Greeks and Romabns would have seen nearly the same night sky as we do.
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
Stars stay fixed in a pattern in the sky due to their relative distance from Earth and the rotation of the Earth. This pattern is known as the celestial sphere. The stars appear to move across the sky due to the Earth's rotation, but their positions relative to each other remain constant over long periods of time.
Stars appear to move across the sky due to Earth's rotation, but they do have fixed positions relative to each other in the sky. These positions can be tracked using a coordinate system called right ascension and declination. However, stars themselves do move slowly over very long periods of time due to their own motion through the galaxy.

Yes, they do. Why? Because they can't remain static forever. Assuming they were ever static (motionless) with relation to one another (an assumption that is NOT true), they would start to move, eventually, due to their gravitatioal force on one another.
This is an illusion due to the vast distances between the stars and the Earth's spin. The stars themselves are moving quite quickly, the Earth spinning on it's axis only adds to this cosmic slight of hand by turning under them. The movement of the stars is over vast distances greater than you can imagine. Always remember, most of the movement observed is the Earth moving not the stars. Our eyes simply cannot detect it over the vast light years.
Stars are extremely far apart from each other in space, so the likelihood of them physically colliding as they move is very low. Additionally, the vast distances and speeds at which stars move help prevent collisions. The gravitational force between stars keeps them in their orbits and prevents them from bumping into each other.
A fault
A fault.
Two parts that are joined, but can move relative to each other.
Yes, all stars have a relative position and they al move within certain limits. Most stars move visually very slowly, so the Greeks and Romabns would have seen nearly the same night sky as we do.
the large sections of the earth's crust that move relative to each other
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
It consist of large sections called tectonic plates, which move relative to each other.
The fracture along blocks of crust (tectonic plates) is called a "fault" or "fault line".
