Something interesting about the lives of stars!

Life of's an interesting process. And to think it happens all around us.

Read the following article.

Take note of how the star's life begins, with a gravitational disturbance from a nearby exploding star called a supernova.

From Craig Freudenrich in HowStarsWork
Life of a Star
As we mentioned before, stars are large balls of gases. New stars form from large, cold (10 degrees Kelvin) clouds of dust and gas (mostly hydrogen) that lie between existing stars in a galaxy.

  1. Usually, some type of gravity disturbance happens to the cloud such as the passage of a nearby star or the shock wave from an exploding supernova.
  2. The disturbance causes clumps to form inside the cloud.
  3. The clumps collapse inward drawing gas inward by gravity.
  4. The collapsing clump compresses and heats up.

  9. When the temperature of the protostar reaches about 7 million degrees Kelvin, hydrogen begins to fuse to make helium and release energy.

Stars More Massive Than the Sun
When the core runs out of hydrogen, these stars fuse helium into carbon just like the Sun. However, after the helium is gone, their mass is enough to fuse carbon into heavier elements such as oxygen, neon, silicon, magnesium, sulfur and iron. Once the core has turned to iron, it can burn no longer. The star collapses by its own gravity and the iron core heats up. The core becomes so tightly packed that protons and electrons merge to form neutrons. In less than a second, the iron core, which is about the size of the Earth, shrinks to a neutron core with a radius of about 6 miles (10 kilometers). The outer layers of the star fall inward on the neutron core, thereby crushing it further. The core heats to billions of degrees and explodes (supernova), thereby releasing large amounts of energy and material into space. The shock wave from the supernova can initiate star formation in other interstellar clouds. The remains of the core can form a neutron star or a black hole depending upon the mass of the original star.

My Interpretation

Take notice of how a star dies. In its final process, it creates a supernova where it explodes and creates a shock wave. This shock wave can and does initiate star formations nearby. I found this very relevant to my own beliefs.

I believe in reincarnation, that nobody ever ultimately dies. They always return to this world to continue living, to serve their karma. This concept of star life and death emphasizes and sort of philosophically proves it. Just imagine a massive star running out of its nuclear hydrogen fuel. Something like a person reaching his last few days of life. The star undergoes many changes and ultimately, or most of the time, explodes. This is signified by the person's death. However, the explosion triggers nearby gas clouds to clump together and form another star. This is signified by the life of another coming to this world, ready to live and thrive. This young one lives and thrives till he reaches his supernova, or death, only to continue the eternal process again.

When i thought of this, it seemed so powerful and profoundly simple. That this eternal law of life even projects itself through the dynamism of the heavens and it is simply continuous; there being no power to stop it.
