WELCOME TO OUR SITE

Welcome to the Our Web site. Simple, clean design should allow you to find the information you need with ease and speed. We continue to work with the information about USA IDM Scene and make our site accessible to people who little known about it. You'll notice that the typeface for our content is larger, which should make it easier for everyone to read. We've included descriptions of GRAVITATIONAL PRINCIPLES AND MATHEMATICS, CRITICAL PHENOMENA, GRAVITATIONAL LENSE, HUBBLE VIEWS DISTANT GALAXIES THROUGH A COSMIC LENS and JOURNEY TO A BLACK HOLE

The beginning

Hubble Physicists recognize that the whole of the physical world can be described in terms of four basic forces. Two of these are concerned with the innermost structure of atoms, and a third, the electromagnetic force, dominates the interaction of atoms with each other. The fourth, and by far the weakest of these forces, is gravity. It is therefore only significant when enormous numbers of atoms are collected together into objects the size of the Earth, or bigger. Gravity is the dominant force in the lives and deaths of stars and galaxies.

Any atom, or collection of atoms, has a property called mass, which measures how much material there is in the object. On the surface of the Earth the gravity of the Earth pulls downwards on all masses giving the sensation of weight. On the surface of the Moon this pull, or weight, is only one sixth of that on the Earth, and so weight depends on where you are, whereas mass is an intrinsic property of all objects.
