In my experience, most people who I have met that do not believe in the Big Bang Theory, do not understand the Big Bang Theory. The evidence speaks for itself... If there was a giant expansion of the universe that gave us what we see today, then there would be a slight hue of radiation emanating evenly throughout the universe. Guess what. There is. Objects within the universe would be hurled outwards in all directions. Guess what. There are.
Also, lets emphasize 'EXPANSION' Not explosion. In an explosion objects are hurled outwards in all directions and from that instant onward, they begin to slow down due to gravitational pull. What we have here is something different. Objects in our universe not only appear to be moving away from one another, but they appear to be doing it at an increasing rate of speed.
If things continue as they are today eventually the hydrogen will run out and our stars will shut down. The giant stars will become black holes and they will become more and more massive as they eat their way through the galaxies and merge with one another. Eventually the black holes will evaporate and the energy from them will be dispersed over an empty space so vast that our minds could never grasp it. I've even heard talk of subatomic particles being ripped apart by the expansion of space.
And if you really want to trip out, check out quantum mechanics. See how whenever we try to locate a particular subatomic particle it seemingly can exist ANYWHERE in the universe. Objects in one corner of the universe can affect objects at another corner. Or how about super strings? I need to smoke a bowl....
