Everyone is familiar with the balloon analogy in big bang theory. We picture a balloon that has galaxies and stellar objects drawn on its surface, and as it is blown up the distance between the galaxies increases. This is a 2d model of how our universe is expanding. In this model, we see the balloon expanding in a direction (outward) that is at right angles to the two spatial dimensions of the balloons surface. This causes objects on the surface to recede from one another, but this is simply a side effect of the expansion of the universe itself. One of the basic concepts in the science of motion is that forces that act at right angles to one another have no affect on each other. If we take the balloon analogy to be representative of the universe we live in, then we must conclude that gravity cannot affect the expansion of the universe itself. It acts at right angles to the direction in which the universe is expanding.

Maybe this is a gross oversimplification. Maybe the balloon analogy is not really how our universe works. But because the implications of gravity not slowing down the expansion of the universe are so great, I think cosmologists should to at least examine the simple harmonic universe model as it takes this into account. To my knowledge, no other cosmological model claims as one of its tenets that gravity is not affecting the expansion of the universe.

The galaxies and objects IN the universe are not receding from one another, they are simply following geodesic paths along the surface of the five dimensional sphere.

.. and ours is direct. We are stuck with lower dimensional models if we wish understand the bigger picture.

Maybe another was to see it is like this: We can use conventional big bang theory to plot a graph of the distance between two given galaxies over time. This graph is determined by the initial expansion of the universe and gravity (and inflation and dark energy or whatever else you throw in). But in the big bang model, the graph is determined by how the universe evolves over time.

Obviously there is no measurable proof of this. It is simply the main tenet of the simple harmonic universe model. Again, I am not asking anyone to believe this theory. All I want is for this model to be considered as a viable cosmological model. The universe is going to be the way it is despite our beliefs. The universe does not care which theory we like. It is what it is. I just think that cosmologists have overlooked a perfectly legitimate cosmological model. How the universe progresses over time is way outside our ability to observe. At this point, the graph (in the simple harmonic universe model) is still nearly straight. The universe may not reach its maximum size for trillions of years. We have no way to know at this time. The deviation from a straight line is too small.

The main tenet of the Simple Harmonic Universe is that the expansion of the universe follows simple harmonic motion. A graph of this motion simply shows what is happening. The difference between this model and the standard big bang model is that the standard model has gravity slowing down the expansion. The simple harmonic model says that the expansion rate, size and other properties of the universe are determined geometrically and that gravity between objects in the universe has no effect on them. It is progression along the outside of the hyperverse that determines its size at any point in time.
