Comet Origins II

In continuing the theme of comets being way outside of expectations, I will discuss the ultra low albedo of the comet surface (at .02 , it is blacker than tar) Clearly organic matter is at play, perhaps in a particular texture optimized to absorb light and heat. Not only that, it appears stuck firmly onto the "snow" and doesn't disintegrate, even around the holes in the blackness, where matter ejects profusely into the corona.

It would appear that the ejection of matter of comets would satisfy one requirement of metabolism - that of making the surroundings more random. One can assume that the inside may thus become ordered and enable complexity. The edge of the comet nucleus is an analogue of a cell membrane - it lets randomness out, and importantly, can let energy in. Solar energy is absorbed by the low albedo, and any particle or clump of radioactive material would melt the snow due to its related heat, and enter into the protected part under the snow, helping to keep the water liquid, and perhaps to help power the metabolism also.

Chemical energy, would be stored analogously to life as we know it, in sugars and various other chemicals. Of course, if there is a central control to consciously pilot the comet to its future direction and gravity assists and reproduce, it needs a brain. Surely DNA, would be the brains rather than a reproductivity code, although it would need to reproduce as well.

As well as a brain, for the other observed features of "steering" requires thrust for both rotation and course adjustments, an eye/eyes to pinpoint its precise location and trajectory, and a communication/nervous system to control devices.

For the observed reproduction/ splitting, first the nucleus of the comet nucleus,ie. the heavy elements in the middle have to split up and move to opposite ends of the liquid centre. Then the comet would have to rotate around an axis such that centrifugal forces can stretch the shape. Finally, a snow fill in between the two sides for new walls, and then have two loosely connected comets until it goes close enough to a planet for tidal forces to pull the two halves away from each other and make their orbits different.
