Comparing Angular Rates of Star Rotation at Different Latitudes and Longitudes

AI Thread Summary
The Earth's rotational velocity at the Equator is 1,674.4 km/h, which corresponds to an angular rate of approximately 15 degrees per hour for stars. Stars at the equator appear to rotate at this same angular rate, while those near the poles exhibit a slower apparent velocity. It is crucial to differentiate between linear and angular rates when discussing star movement. The stars do not move at the same linear speed as the Earth's rotation; instead, the angular rate remains consistent regardless of latitude. Therefore, the apparent motion of stars varies significantly based on their position in the sky.

The Earth's rotational velocity at the Equator is 1,674.4 km/h or 465.1 m/s. The stars at the equator rotate at that same rate taking in account Precession at that particular time of the year and the longitude & latitude they are viewed from. Do the stars at the poles rotate faster then at the equator also depending the longitude & latitude they are viewed from?

No. Another way of looking at it by imagining the sky is rotating around the Earth instead. The stars near the poles move much slower in apparent velocity than the ones near the equator do.

No, be careful. It makes no sense to compare the linear rates (the stars don't move at 1674 km/h). It's the angular rate (of about 15 degrees/hr) that is the same.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
