Question
The mass scale of the universe In the lectures we have been exploring the "scales" of the various physical dimensions, including length, time and energy. Now it is your chance to construct an astrophysically meaningful mass scale following the same approach (a) What is the smallest mass for an object that is important in the universe? What is the largest? Justify your answers. (b) Identify (and list) three additional characteristic mass values based on the properties of objects that contribute significantly to the total mass in the universe. For example, a characteristic mass value in our solar system would be the typical (median) mass of a Kuiper belt object. Clearly justify your choices. (c) Sketch your mass scale in logarithmic units, illustrating the various characteristic values.Explanation / Answer
a) Mass so small that is cannot be observed,measured tested,is unknown,but beleaved to exist,is not mass,it is premass. It is alpha. The substance and evidence is confirmed only by our strong, unwarning belief that all things visible are made of things not visible. b) Three additional charateristic mass value based on the properties of objects that contribute significantly to the total mass in the universe : 1. Initial mass measured an object resistance to being acclerated by a force (F=ma) 2. Active gravitational mass measure the gravitational force exerted by an object. 3. Passive gravitational mass measured the gravitational force exerted on an object in a known gravatational field.
