Musings on our sun and about us...

The sun is large. Its volume is 1.3 million times that of Earth. It’s mass, however, is thought to be around 336,000 times that of Earth. With that in mind, at only 336,000 times the mass of Earth it is able to anchor of all the other planets in the solar system with its gravity well. At that much mass constitutes %98 of the matter in our solar system. Leaving a paltry 2% to compose of all the other planets, including Jupiter. Our sun is a medium sized star. A medium sized star at one our distance from it is able to keep our oceans in a liquid form and hold us close to it, our planet being billions of tons of iron. Now put this in perspective, a ball of gas accomplishes this. It accomplishes this by simply being in quantity and not even being all that dense. The very core of the sun may have a great density to it...but for the most part the sun is not a very dense object.

If you were magically impervious to the vacuum of space and to heat, and you were launched toward the sun you would fall right through its surface. What you would see on your way down is not entirely known, but it is definite that you’ll fall right in.

The neat thing about the sun is the fusion reaction, of course. This wonderful dynamo, at least I believe, may be responsible for the periodic table as we know it. What happens with fusion? Simple, the electrons separate from the rest of the atom due to the high energy state or collision, and the nucleus impacts with another nucleus. In some cases changing how many protons and/or neutrons or even electrons present in the new atom. It is thus, the foundation for the nebular theory.

Our solar system having at one point having been a supermassive star that died throws the age of the universe back into question. Who really knows? Let’s say we really are the descendants of a supermassive star. It’s lifespan had to have been billions of years, and thus went supernova. Perhaps its core did not turn into a black hole, but itself exploded with the rest of the mass of the star. If it had been fusing atoms for a very long time we’d have a lot more than just hydrogen, we’d have all sorts of atoms now in the nebula, or corpse, of this once great star...and thus our periodic table.

The possibilities that I would like to explore here are when we get cold fusion finally to being feasible. The next step is to be able to use different types of fuel for this. We’d then be to the point to where we can engineer what types of atoms we can create. We’d then be able to engineer molecules for new building materials at a subatomic level. Just imagine if we happened to stumble across a metal that is twice as resilient as titanium.

I dunno, just misc musings. If I’m way off base, any scientists out there, please educate me :)

I guess you could say the point I was trying to make, if you call the sun a life form, and you compare us to stars...how significant are we?
