I apologize for my       words upsetting you. My fault for not double checking before sending a       post. I do not think your understanding of physics shallow.              I can give you a little trick that I use to prevent this. Just before       sending I reread my post to make sure it does not make me feel       good. Feeling good is the red flag that this is not a physics post so       rewrite it. Works for me :<).              And to show I do have respect for your physics I will raise the bar a       bit. 2 objects of equal mass are moving away from each other at .1 c       caused by an explosion between them . Equal mass and equal speed so       momentum is conserved. One fly in the soup. One of the masses is       radioactively decaying losing mass over time. How is momentum conserved       under these conditions. I do not have a clear answer to this question.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
