In summary, the conversation discusses the rotation of a celestial body and how its angular momentum and rate of rotation are affected by its bulge and spin. It is noted that the rotation speed is irregular and there may be a loss or gain of energy depending on the balance of gravitational and centrifugal forces. The origin and effects of this energy are also questioned.

Will the equatorial radius keep on increasing? Will it become flatter and flatter ?

Angular momentum
Since it bulges as it rotates, its angular momentum should decrease. So its rate of rotation would decrease too. But if its rotation slows down, its bulge would also decrease and its spin would increase again! So its rotation speed is irregular.

Since it's rotating fast, I think it takes quite long to slow down to the extent that gravitational force outweights the centrifugal effect.
Energy = 0.5Iw^2=0.5(Iw)w (I:moment of inertia ; w:angular velocity)
As w decrease, there is loss in KE. Where does the loss in KE go to?(gravitational wave?)
When gravitation outweights centrifugal force, w increase, where does the energy come from?
1. What makes these stars strange and puzzling to astronomers?
These stars, also known as "pulsars", emit beams of electromagnetic radiation that are highly regular and precise, leading scientists to believe that they may be signals from intelligent life forms. This has not been confirmed, however, and the exact mechanism behind these emissions is still not fully understood.
2. How do pulsars differ from other stars?
While most stars emit light and heat due to nuclear fusion reactions in their cores, pulsars emit radiation from their magnetic poles. They also rotate at incredibly high speeds, making them appear to "pulse" when observed from Earth.
3. Are these pulsars found in specific regions of the universe?
Pulsars are found in various types of galaxies, including our own Milky Way. They are commonly found in binary systems, where they orbit around another star, but some are also found in isolation.
4. Can we detect these pulsars with our current technology?
Yes, pulsars have been detected and studied for decades, using various instruments such as radio telescopes and X-ray detectors. However, the recent discovery of a repeating pattern in the signals from some pulsars has sparked renewed interest and research in this field.
5. What implications do these pulsars have for our understanding of the universe?
Pulsars provide valuable insights into the physical processes and extreme conditions that exist in the universe. They also have practical applications, such as being used as a tool for navigation in space. Additionally, the possibility of these signals being evidence of extraterrestrial life raises profound questions about the existence of other intelligent beings in the universe.
