Edge Effects for the Universe?

Physics
[caption id="attachment_7377" align="alignright" width="480"] Introducing the universe.[/caption] A strange thought crossed my mind. I was in that twilight state between awareness and sleep. What about the edges of the universe? Does the universe experience edge effects? Materials all have their own properties. Metals, for instance, have a melting point. They have conductivity, density, malleability, and ductility. Liquids, gases, and plasmas have properties as well. A material or an object can act differently at its interior, than at its edge. Consider some objects interacting with electromagnetic radiation. Magnets and Capacitors Capacitors exhibit so called Casimir edge effects. The electrical field between capacitor plates behaves differently at the edges, than between the centers. The same is true of the edges of magnets. Frequency Skin Effect Electrical engineers understand the high frequency skin…

Where Does Light Go? Why is the Universe Dark?

Astronomy
[caption id="attachment_3236" align="alignright" width="480"] The Andromeda Galaxy (M31)[/caption] Where does light emitted from a flashlight go? On a universal scale, what happens to all the light? If Space is not infinite, goes the line of incorrect reasoning, then all the light that has ever been radiated by stars and galaxies should make the Universe a blindingly bright place. Hence, the universe, based on this reasoning, must be infinite. But, if the Universe is not infinite, the light should bounce back and forth, building up. Most scientists consider the universe to be expanding, yet not infinite. So where does all the light go? First, let's discuss what light actually is. What Is It? Light is a form of energy that radiates outward — radiant energy. Radiant energy can be readily absorbed,…
