Yes, the zenith distance at upper culmination is less than the zenith distance at lower culmination. The zenith distance is the angle between the zenith (straight overhead point) and a celestial body. At upper culmination, the body is closest to the zenith, resulting in a smaller zenith distance. At lower culmination, the body is furthest from the zenith, leading to a greater zenith distance.
No, zenith and the North Star are not the same. The zenith is the point directly above an observer, whereas the North Star (Polaris) is a star located near the celestial North Pole in the Northern Hemisphere, making it useful for navigation.
An observer at a latitude of 79 degrees North will see the Sun at the zenith on the summer solstice, around June 21. This is when the Sun reaches its highest point in the sky and appears directly overhead at noon.

Galilean relativity asserts that the passage of time is the same for all observers. Einsteinian relativity does not claim universal time for all observers. Instead, it asserts that the speed of light and the fundamental laws of physics are the same for all observers.
The two observers would each measure light to be the same. The speed of light is the same for all observers, regardless of their frames of reference.

No, not all stars pass through the zenith. The zenith is the point directly overhead an observer, so stars that are close to the celestial pole (North or South) may not pass through the zenith at all from certain locations on Earth. Stars near the celestial equator are more likely to pass through the zenith as they appear to move across the sky.
It depends on the observer's frame of reference. If both are stationary then an object's speed will be measured to be the same. If one or both are moving at unequal velocities, then the same object will appear to move at a different speed for each observer.
For the Special Theory of Relativity, the basic postulates are:The relativity principle, i.e., laws of nature are the same for observers in different reference frames.The speed of light is the same for different observers.
No, zenith and the North Star are not the same. The zenith is the point directly above an observer, whereas the North Star (Polaris) is a star located near the celestial North Pole in the Northern Hemisphere, making it useful for navigation.
The postulate of general relativity states that the laws of physics are the same for all observers, regardless of their motion or gravitational field.
The motion of an object appears differently to observers in various frames of reference due to the principle of relativity, which states that the laws of physics are the same for all observers in uniform motion. This means that the perception of an object's motion can vary depending on the observer's relative position and velocity.
