Gravity and Accelerating Universal Expansion by Peter Noble

This theory came to me in the bath, so it must be right. It offers meanderings on gravity and universal expansion.

Since Edwin Hubble first found evidence that the universe is expanding, cosmologists have pondered whether the universe will continue expanding forever or if the expansion will eventually slow down and even reverse resulting in a “big crunch”. To this end they have tried to measure the rate of universal expansion by studying supernova explosions in distant galaxies. The one thing they were not expecting to find was that the rate of universal expansion is accelerating. That is indeed what they appear to have discovered.

Einstein showed that time and space are indivisible and should be considered as single fabric called space-time. The faster you travel in space the slower you travel in time with the total never exceeding the speed of light C.

The universe is expanding. It would like to expand at the speed of light. It is easy for light and radiation to travel at C, it’s not so easy to get things like pencil sharpeners and planets to whistle along so fast. The expanding wave front of the universe (we call it the present) is made uneven by the fact that matter just cannot keep up with energy. The effect that a concentration of matter has on the space-time that surrounds it is to act as drag on its expansion.

Why is universal expansion accelerating?

As time passes matter degrades to radiation of various forms. Stars make this conversion from matter to energy at a prodigious rate.  There are no circumstances where radiation degrades to become matter. It’s a one way trip with a huge exchange ratio E=MC2. A tiny amount of matter yields a whole lot of radiation. As the universe ages, the balance of matter and energy tips, always in favour of energy and energy travels at or around C. Thus the brake put on Universal expansion by matter is being eroded and the universe expands faster and faster, reaching C when all the matter is degraded to energy.

Further cogitations on the nature of gravity.

Gravity is a slippery customer. Newton thought of it as a force. Einstein showed that it was in fact a property of the fabric of space. Even Einsteins model is unsatisfactory as colossal amounts of invisible “dark matter” have to be invoked to make it work on a galactic scale.

I have a description of gravity, I shall call the  “expanding present”.

I propose that gravity is a result of the shape of the expanding wave-front of the universe. We experience this expanding wave-front as the “present”. As mentioned in previous paragraphs, light and energy  can travel at the speed of light but objects with mass cannot.  So parts of the universe with mass expand more slowly than those without. This leads to a lumpiness in the shape of the universal wave-front as it expands. This lumpiness is gravity.

The traditional understanding of gravity is as an attractive force between masses, transmitting this force by exchange of a theoretical particle, the graviton, which has never been detected. I propose that we see gravity not as a force but as the acceleration required to negotiate the expanding present.

Considering gravity in terms of the shape of the expanding present may offer ways to resolve the contradictions between theory and observation which can currently only be resolved by postulating the existence of enormous quantities of “dark matter”. So instead of invoking dark matter we can perhaps invoke tension or stretching in the expanding wave-front of the universe.

So if any of that is correct it just leaves us asking “what is mass?” rather than “what is gravity?”. I ‘ll have a stab at that one too. Mass is just clumpy bits of space-time. Using the analogy of an inflating balloon, mass is the bits of balloon material where the rubber is a bit thicker or knotted together.

This leads me on rather neatly to my creation theory.
