    According to theory, the universe has been ever expanding since the Big Bang. Is the force from that initial event the only cause of the expansion of our universe?

    Also, if that happens to be true. Would the force of gravity slow the universe's expansion to a point where it stops all-together?

    since gravity affects matter in an infinite distance in all directions, would it not be true that the universe would begin to contract?

    Lastly, because gravity would be the only force affecting all the galaxies, would they over time condense into an infintesimally small and dense black hole, recreating the initial conditions for the Big Bang?

    Up until about 1998 it was thought that the expansion of the universe was the result of whatever the initial conditions of the Big Bang might have been. The open problem in cosmology was whether the gravitational field attributable to all of the mass in the universe was sufficiently strong to bring the expanison to a stop, and perhap to reverse it and cause a subsequent contraction. There were three possible cases: 1) continual expansion, 2) continual expansion decaying asymptotically to zero in infinite time and 3) an eventual cessation of expansion followed by contraction.

    However, it was discovered by observations of type 1A supernovas that the expansion of the universe is actually accelerating. That has resulted in the hypothesis of "dark energy" which supplies a force that counteracts gravity on large scales and results in an ever-increasing rate of expansion. Nobody know what dark energy is, if it really exists, and if it does exist what it is.

    You can add to the uncertainty the theory of inflation, which is also attributable to an unknown cause (some undefined scalar inflatin field related to the physics of elementary particles). Whether or not inflation is a continuing process, or for that matter whether it is a correct theory, is still unknown.

    The majority of the human population is missing the most important piece of intellect. And that is that all the information that we gather today is based on the information that we gathered in the past. This is because information is simply derived from observations of our world and the laws and physics of history are the complete knowledge of that particular time period. They still hold true because they represent the world as it was observed many years ago and the world has not had a significant amount of time to affect change. Now think of this if the theories that we come up with today are based on incomplete information from the past then we must still be missing some vital piece of info right? these things are obvious to us because everything i am saying is already recorded somewhere in our sub-conscious we have simply forgotten how to "manually" draw information from our sub-conscious, that is we simply control our conscious mind and let our sub-conscious govern itself. the reason we have forgotten is simply because we have been depending on the information provided by recorded history to educate us on our present world. Since the techniques used to observe the world were so primitive in the past then our understanding of the world is still primitive. my theory is that e=mc^2 is definately the most influential piece of of information from our past so it must be "along the right track" but is still not entirely complete. I have gone back and studied einstien's work not to learn what he knew but to understand how he came up with his information. what observations did he make that led him to believe the things he recorded?

    Dr. Rocket...thanks for making your info so clear...I was even able to understand it!

    sorry guys after reviewing what i wrote then paying attention to the rest of the information available. i realize that i hijacked your thread. i will start a new one and explain my theory in more detail in an attempt to gain some collaboration on the ideas.

    based on my understanding of the world and no one else's so far as i can tell (except some of the greatest minds in history) the following is the real answer to your questions....

    The universe will eventually contract but not in the sense that we are led to believe. Matter will eventually revert back to its basic form (energy) and the universe as we perceive it will cease to exist. the forms of energy(four fundamental forces) that are left will then revert back to their basic form (a unified energy form) This information has been "known" since the dawn of existence..not time...existence. we were simply unable to perceive this info because of our primitive existence....Now to explain. Basically it comes down to the fundamental law of the entire universe.(yes the thing all of the scientific community is looking for) I believe religion was the first to attempt to understand it, but the primitive observations of the world at the time led to incomplete information. that incomplete information has reverberated throughout history to severely affect our current understanding of the world.(i believe) Albert Einstein was the first modern day individual to figure this out and was able to produce some of the greatest mathematical explanations of our current universe. But the problem was he too had incomplete information. I believe i have finished Einstein's understanding and discovered the key to the "Theory of Everything". I have revised the famous E=mC^2 (and you will be surprised at how many modern inconsistencies that it has solved for me). Now all i need is a little collaboration from some more specialized intelligence. Once our intelligence is complete though we are doomed to begin the process of contraction. that is the next real problem that we will have to solve.

    (I will even go as far as saying that i understand exactly why we have not been able to figure this out until now. Its a basic flaw in a very new concept in physics and mathematics today. Chaos Theory)

    one last key point i forgot to mention is that existence is a cycle based on the mathematical formula that i have developed from Einstein's understanding. Once the universe is reverted back to its original form the process of expansion restarts. Hence the big bang is simply one instance of a never ending cycle of big bangs.

    just a thought based on a theory i'm working on:

    if matter is the product of interference patterns, then the individual points of interference would propagate away from each other at equal rates and distances per unit of time. the contraction of the universe, caused by the four fundamental forces we know of, would be the result of wave-function collapse at different scales involving multiple individual particles of collapsed waves, which together act as another wave system and is effectively in superposition between all contained collapsed particles.
    I prefer to use my right brain to study the universe rather than my left brain.

    wow that actually seems to make sense in the theory im currently working on. I am attempting to organize my ideas into a massive collective archive and present it to anyone and all who will help me to understand the details and implications. I have started a new thread and i have posted the initial comment that explains the basis of my theory. My theory as i understand it explains every physical system that i am aware of. But that is my problem. I am but one man and my intelligence is minuscule in comparison to that of the scientific community. (Ha that is part of my theory.)
