An observer at latitude 79°, whether north or south, can never see the sun at his zenith. That's only possible for observers whose latitude is less than 23.5°, either north or south.
No they are exactly the same. See Deng Lecture 1
No. The North Star, also called Polaris, is a star that is almost directly above the north pole. The zenith is the highest point an object reaches in the sky.
That's the observer's 'zenith'. Since it's referenced to the "observer's head", each observer has a different zenith.
If you want to get technically precise, then for a single observer who stays putin the same place, it would be a very rare occurrence. But you can be sure thatthe moon is precisely at the zenith for a point somewhereon the equator every13.7 days.
The zenith.
30 degrees for observers at a latitude of 30 degrees north
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.

The ZENITH .
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.

It appears Zenith gas refers to gas obtained from the Zenith Oil and Gas company.
Hey Zenith! Awesome! LOLZ
