I would love to hear someone talk about this actually as it has been my pet theory for the last 15 years since high school physics.

My reasoning was p = mv. m drops (through various processes in a star emitting energi==mass) and since p is constant, v increases.

Probably totally naive, but it is just a thought which has stuck around with me.

If the star is emitting massive particles, then it doesn't have constant momentum.
