The gas and dust in space - what is the dust, just debris from collisions of things? And why don't they aggregate and form spheres of some kind? Or are they in the process of doing so?

Think about how many cubic light years of space there is!<br /><font color="yellow"><br />Or are they in the process of doing so? </font><br /><br />In certain areas of our galaxy (and others) it is. But in intergalactic space, it's not likely. <div class="Discussion_UserSignature"> <p><font size="4"><strong></strong></font></p> </div>
