Howdy.....Everything is a by-product.....ergo,,,, a fraction of cause and effect,,,,,from larger actions come smaller by-products.......with that understood, you can consider other ways in which geometry and its density can come into existence. i.e. mc2 which is density.......The galaxy that you see is only about 1/10 of the true size of the total bonded forces which is that galaxy (depending upon the type of galaxy will dictate the true integer of total size)(as well as the strengths of the fractions of the formation process.) I find it very interesting that when varying a little bit of formation fractions, it will change the evolution of the object. Similar to but not the same as. I can tell you how it is done from my perspective, and that would be only one of millions. Everyone has their own perspective of formation styles. So I say measure your definitions, look to the basics, for it is only when the basic is more basic that Science advances. It is the basic that you measure. The device you use to measure with may become a new tool. Some tools are very useful to further the quality of being Human......Life, Liberty, Freedom is Naturally Sacred, Vote.....Vote for it to survive. stop tyranny.........My name is Uncle Sam, I say,,, Let My People Go....I as all are, am private, leave my life alone.....The public is secure as long as the vote is honest and secure.......I make my own money, don't steal it from me to pay for peoples failures. The beauty of American Capitalism is that people amass wealth, because people have a natural trait known as benevolence, philanthropy evolves and charities come into existence, privately owned. Be there failures, people will reach down and lift them up.....Not the role of governments at tax payers expense. Not any aspect of a persons life should government be involved with......unless harm is involved.
