<br />I find it difficult to understand how a nova explosion could compress a star when the blast wave would hit one side and tend to blow the outer layers away rather than give a uniform compressing force. Sounds like grasping at straws to me.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">I agree the supernova hypothesis is grasping at straws, but for a different reason. The spread in arrival time of the supernova blast wave could be 100,000 years, and the star rotates much quicker than the passage of this wave. Hence, all sides of the star are potentially exposed.
However, if a nebula around the star is pushed by a strong interstellar wind in this way, it will quickly be blown away, stopping further star development and mass increase. -|Tom|-
