The Steady State Universe Theory Originated by *Fred Hoyle in 1948, this theory says that, in the space between galaxies, new matter is quietly but continually appearing out of nothing. In 1965, Hoyle publicly abandoned the theory as ridiculous.
· The Oscillating Universe Theory This is another idea by *George Gamow. It says that when the universe finally runs down, another Big Bang will start it going again. The main difference is that, while the first Bang occurred when nothing exploded into all the matter in the universe, the later ones would be the result of all the matter packing into a tiny point and then exploding again.
· The Nebular Hypothesis (also called the Planetesimal Theory) says that, as the gas swirled around, eddies of gas caused the sun and planets. All seven theories require circling gas which contracts into the sun. We have already disproved the basics underlying this concept. Many say that material from the sun made the planets and moons. But the elemental composition of each of the planets is different from the sun and from one another. One could not come from the other. In addition, the sun would have to rotate extremely fast to hurl off planets and moons, yet it rotates very slowly. More on this later.
· The Fision Theory says that our sun burst and sent out the planets and moons. But they would fly outward forever; they would not stop and begin circling the sun or one another.
· The Capture Theory says our planets and moons were wandering around and were captured by our sun. But they would then crash into the sun; they would not circle it or one another. We never see planets or moons flying by us today, yet we now know of at least 150 moons in our solar system (Jet Propulsion Laboratory, 2006).
· The Accretion Theory says that small chunks of material gradually got together and formed our planet. Then more chunks formed our moon, which began circling us. This idea is pretty far out also. The planets, moons, and asteroids are all in carefully arranged orbits. The meteors fly fast in linear motion. No chunks are just floating around, and those chunks would not stick together anyway.
· The Planetary Collision Theory says our world collided with a small planet, producing our moon. But such an impact would totally destroy our planet. How could such an impact produce a circling moon? This would have had to be repeated for all 150 moons in our solar system. The theory would require thousands of planets passing through our solar system, for enough direct hits to produce all our moons. Why are not such flybys occurring today?
· The Stellar Collision Theory says that two stars collided, and produced our planets and moons. But they would not then pause and circle one of the suns which was waiting placidly to receive them. They would either be hurled away from the sun or crash back into it.
· The Gas Cloud Theory says gas clouds were pulled in from outer space by our sun's gravity; then they paused, formed themselves into planets and moons, and began circling one another. But gas does not clump, and linear motion toward the sun would not change into circular motion around it.

The Big Bang Theory holds that everything in the universe, stars, galaxies, radiation, interstellar gas, everything was created in one huge explosion. Since that time all of the matter in the universe is hurtling outward at speeds that increase with the distance from the site of the explosion, and which approach the speed of light for the most distant objects.
There are several versions of the Big Bang Theory, but in its purest form, all the matter and energy in the universe suddenly sprang into existence at some point estimated to be about 13.5 billion years ago. This matter and energy instantaneously came into being, forming a mass no bigger than a proton. Prior to that instant, nothing existed, no matter, no energy, not even empty space or time itself.
The Big Bang Theory explains the red shift, and also some of the background radiation that has been observed. But it explains little else. In particular, it fails to explain why the matter in the universe is distributed so unevenly.
