Two machanisms have been discussed to give rise to a SN Ia: 1. A single white dwarf collects matter e.g. from the outflow of an accompanying red giant. As...

I hadn't planned to post again on this topic, but some of the nonsense written has been too painful to stand. I beg the other posters to look at a textbook or...

Is there enough information to state the acceleration is directly towards the sun ? What if there is an acceleration towards the earth ? Isn't this worth...

In the newsgroup sci.physics.relativity I started a posting with the subject title. The purpose was how do you simulate the movement of the planets, specific...
