nebula: glimpses of th(is)e wh(s)o(u)le world

we can only see those fraction of interstellar dust being intercepted by our instrument in the 1 AU distance range from the sun. Less polymer organic substances than those found can survive in grains only in the coldness of far space. They evaporate in the solar system. Graphite grains or those constituted by very large PAH's, if at all present, would be hindered from entering the inner solar system by radiation pressure. Nevertheless, some speculation may be allowed about the formation and constitution of that solid interstellar matter for which entry to our habitat range is prohibited. Looking to the chemistry of original interstellar gas (!) surrounding far stars, a fraction of highly unsaturated carbon chain molecules and the contribution of nitrogen and oxygen to them is remarkable. Hydrogen interacts far less than its abundance there might let us think. These unsaturated molecules, however, are highly reactive, even by simple two-body collisions due to their many inner degrees of freedom. Thus they polymerize and cyclisize in the cooler parts (below 1000 K) of interstellar space. Their aggregation to dust particles, such as those we have seen, is thus easily possible. Also the "diffuse clouds" have optical properties compatible with homologues of such matter. A lot of investigations are still ongoing. We are lucky to have for the first time matter from alien stars "in our hands," as it may have also formed our solar system billons of years ago. This is the origin of the matter that constitutes life.

that was confusing. Your point and question came too late for me to follow and stay interested. perhaps giving a better background before u jump right in would help (or maybe i'm just not smart enough to understand)

 

ok here is the new beginning to all that.

the phoenix is regarded through many anceint cultures as the fiery feathered serpent of death that from the ashes rises again life. the symbol of death, life, and rebirth taking flight through the vastness of the world. comets are bringers of fire, and look like a bird serpant flying through the sky. however when they impact a planet they are fiery bringers of destruction and renewal. many leading thinkers, such as Graham Hancock, believe by interconnections between stories of the arrival of the phoenix to earth and comets, they are yet another example of myth actually being stories of events that happened in anceint past passed down by mouth through countless generations. read "hamlets mill".
comets can be big, big enough to wipe out life on a planet and dawn a long ice age. however, after cataclysms of such life always blooms, through core samples dating time in carbon back to millions of years. we know viruses can travel on asteroids and comets through space and land on pristine shores. due to their nature to live, they are perhaps the link between life and death as we know in a bad way. but we know there is a good to make of a virus, and venom from snakes, and anything commonly associated with being bad, usually you can derive from the very source the antidote. to everything there is a balance.
life and death, yin and yang, phoenix promise of life anew.
