I have no problems with the theory of the big bang and expanding universe, but this is a fun simple alternative that I am finding hard to break.
Consider a model of the universe where matter starts massive (sub atomic particles miles across) and then shrinks. The universe just condenses out of energy into large scale cold matter. Over many billions of years, this matter shrinks to the size it is now and keeps shrinking, getting hotter as in condenses. (Not as exciting as the big bang)
The key argument being the phrase: “As experienced by matter”.
Anything that cannot be directly or indirectly experiences by matter we know nothing about it.
Therefore, the laws of physics are the laws of the universe as experienced my matter.
As matter shrinks, it experiences a faster speed of light.
That is it takes less time for light to cross the width of a smaller atom, or to travel the length of a ruler made of shrinking atoms. So the ruler measures light travelling a longer distance in a given time period, but only because the ruler is shrinking.
So, in this model we have the speed of light as experienced my matter.
The master speed of light is still absolute but we have no scale to measure it by so its value is unknown.
The speed of light as experienced my matter is increasing with time by a rate derived from the Hubble constant.
(Ho = 2.5 10-18 per second, so speed of light increasing by less than 1 part in ten billion per year)
{You cannot use the wavelength of a reference light to measure against see below}
So now we have two types of distances, those defined by physical units of measurements using instruments made of matter, and distances measured using the speed of light and time.
In this model, the idea is that the universe is not expanding if we measure using the speed of light, but is expanding if we use units of measurements based on matter. However, this is only because the physical units based on matter are shrinking as time passes; each time you use the ruler you read off a bigger number.
The current definition of the metre uses the speed of light so it does not shrink with matter.
In this model, you need to remake your metre rulers 1 atom longer every 6 or 7 years.
I am going to use the old definition of the metre for the rest of this argument.
So in this model, as matter gets smaller it experiences a faster speed of light, and this is the only speed of light known. So “c” in all physics equations is the speed of light as experienced by matter.
{If like me you are trying to break this argument, please double check the following for me}
If you plug an increasing value for the speed of light into equations for the atom, it shrinks and emits shorter wavelength radiation when electrons change state.
So you get a circular argument, as matter shrinks it experiences a faster speed of light, this increases the strength of the electromagnetic force so making the atoms smaller anyway.
Now if this applies to all Boson based forces then the nucleus also shrinks and relative stability of atoms is maintained. {I got totally lost trying to test this}
In this model, we have matter shrinking and emitting shorter wavelength light as it shrinks. Therefore, the wavelength of our reference light sources are shrinking with our instruments, rulers, diffraction gratings etc.
So if we look out into the universe what do we see?
We see old light emitted by matter that was bigger (more fluffy) than modern matter.
When we measure it with our shrinking modern-matter instruments, the wavelength is longer than we expect, but the light has not changed it is still as emitted by the larger scale ancient matter. So, the cosmic redshift is due to us shrinking not relative movement.
{Has everybody already broken this or should I keep typing?}
Consider a long line of galaxies spaced a billion light years apart, but stationary relative to each other. Each galaxy has an identical race of aliens using instruments identical to every atom. They all start emitting an identical reference laser beam at each other.
Assuming the Hubble constant is about 0.08 per billion years, a billion years later when the light reaches the nearest galaxies on each side of the emitters, all the matter in all the galaxies has shrunk. These instruments are now still atom identical to those in the emitting galaxy’s but smaller than a billion years ago, so now measure the billion year old light a 1.08 times longer than their reference is now. When it reaches the next galaxies in line, it is 1.16 times longer than the reference now.
So cosmic redshifts work from all viewpoints equally, but there is no associated time dilation.
{Is lack of time dilation a problem with this model?}
In this model, we need to use the correct units of measurement when thinking about distant / ancient object. They are made of bigger matter than we expect. To make the physics work you need to convert to ancient units of measurements using the Hubble constant and the time difference.
So the physical metre or mile etc was 1.08 times bigger a billion years ago.
So galaxies are not as big as we think, and stars in them are not moving as fast as we think.
Also are they shrinking faster than the stars are flying out of them? (So maybe less dark matter needed)
(I am still trying to guess what this does to decay curves of supernova {Is this a flaw?})
Going back to the start of the universe, where enormous fluffy matter experiencing a very low speed of light.
E = mc2
With a very low value for ‘c’ you can get a very large amount of matter from a tiny amount of energy.
Cosmic background radiation in this model was emitted a microwaves by large-scale matter near the edge of our light cone. Early large matter galaxies may have seen it as red light.
Lastly, in this model dark energy could be considered as energy being lost to intergalactic space as matter emits every more energetic photons with ever decreasing chance of hitting another shrinking galaxy.
I hope that you found this a fun interesting argument even if I have missed a fundamental flaw somewhere.
I need feed back on this for my science fiction book, otherwise the professor of astrophysics in it will look very silly.![]()
