How Would a Halved Earth Mass Affect the Moon's Rotation Period?

AI Thread Summary
A halved Earth mass would likely lead to a slower rotation period for the Moon due to reduced gravitational influence from Earth. The Moon's orbital mechanics would be affected, potentially increasing its velocity at the current position. However, over time, the Moon would adjust to the changes in speed and mass, leading to a correction in its orbit. The discussion highlights the complexity of gravitational interactions and their impact on celestial bodies. Understanding these dynamics is crucial for grasping the Moon's long-term behavior in response to changes in Earth's mass.

Someone texted me and asked me if the Earth was half as massive what impact would that have on the rotation period of the moon?

I'd think that the moon would rotate slower as it's gravity would more influence on the earth. But I am not sure if that makes sense or not haha

\mu would be greater then the velocity would be greater at the present position therefore the Period would decrease but the moon would eventually correct for the change is speed and mass changing the whole orbit.

Thread 'Does it make sense to build new radio telescopes?'

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?'

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...
