Just Saying for the sake. :
The comets are carrying lot of contents with and it may be possible that they are becoming in use for the "sun's functioning" in the sky. Do you think so? The debris of the comets are adjoining the lost mass of the sun in the previous actions over there.
Because most of the comets journey from the Oort cloud to the sun, few of them only caught in gravity like jupiter-shumaker levy comet.
Do you think that Sun is using such stuff into its every time burning process! in such way may be there is a great possibility to keep "the status co ante " of Sun.
