The days from Galileo to Newton gave us a physical universe where the sun had planets orbiting around it. And that solar system was held together by gravity, not physical contact. Gravity was put forth as the attraction gravitational bodies had toward each other. And that was measured by the volume size times the density of material within the volume. Other star (sun) systems were thought to be similar. Star systems have been observed to be gathered into galaxies. The attraction of gravitational bodies toward one another was according to bulk. The more polite word of mass was used. And the mass was the measurement of the body's gravitattional attraction. Gravity even holds portions of gravitational bodies onto the bodies. Such are gases like our atmosphere, liquids like water, and loose solids resting on the earth's surface. And that is adhesion. But material objects, which are called matter, be they gases, liquids, or solids, have internal cohesion not dependent upon gravity. It is the property of elasticity which holds an object together and resists having it torn apart. Energy can be passed through loose objects suclh as air or water by elastic waves that transfer the energy without transfering the source of the energy. But waves cannot occur without some elastic material cohesion that holds the medium of passage together. For waves, object elasticity is necessary. Such was the concept of the physical universe as 1900 AD and the 20lth century approached. Space between gravitational bodies was assumed to have an elastic property called the ether through which light waves passed. But then Michelson and Morley performed an experiment that showed space did not have any elasticity. Theether did not exist. So what medium of matter did the light waves pass through to produce the waves? Einstein suggested that perhaps the light waves were caused by particles, called photons, that actually covered the full distance between the gravitational bodies. Mass and elastic cohesion had been associated together. And the gravity was first uncovered by Newton. Scientists considered mass as merely the math measurement of the elastic cohesion. But then came the discovery of the Lorentz Transformation by Lorentz in the Netherlands and Fitzgerald at Trinity College in Dublin. The Lorentz Transformation showed that as an obaject approached the speed of light, its dimension in direction of travel began to shrink so that, at tne speed of light, the dimension in direction of travel has shrunk to zero. The object no longer had volume. It only had the area of two dimensions. Yet the mass went up to infinity. Volume times density could no longer define mass. The definition of mass had to be changed. So Einstein defined mass as the resistance of the object to having its velocity changed. And it took infinite energy to get infinite resistance to change. That gave E equals m times C squared where E is energy, m is mass resistance, and C is the speed of light. But scientists still associate mass with elastic cohesion of the object, of the gravitational body. So that indicated that space was empty, nothing. And that produced Relativity and the Time Concept. However, that separation of mass and elastic cohesion has to be considered if we are ever to get to the bottom of things. That means space has no elastic ether. But space has mass. Space is not nothing. And the mass belongs to the space, not tothe object that travels the space, not to the gravitational body. But the mass is undetectable to our senses and our instruments because it has no elasticity. This book examines the consequences of space having mass without any elasticity. THE RESULTS ARE TRULY AMAZING.
