Coincidence? Hubble Horizon = Age of the Universe

Let's start with a short overview of the Hubble Horizon taken from this website: Cosmic Horizons – Explaining Science

The Universe is expanding. The further away an object is the faster it is receding from us.

There is a clear relationship between the recessional velocity and the distance of a galaxy. This relationship is known as Hubble’s Law and is written as

v = HoD

where v is the velocity an object is moving away from us
D is the object’s distance
Ho is a constant known as the Hubble constant. If v is measured in kilometres per second and D is in megaparsecs (Mpc) (1 Mpc =3.26 million light years) then Ho is approximately 70 km/s per Mpc. The Hubble constant measures how fast the Universe is expanding. In reality, the Hubble constant changes over time (it is generally believed to be decreasing) and so is more correctly called the Hubble parameter H(t). The Hubble constant is the value of the Hubble parameter today. However, the current rate of change of the Hubble constant is very small. It will take hundreds of millions of years to fall by 1% from its current value.

Assuming that Hubble’s law is valid at all distances, at a separation from us of more than 4,300 Mpc (or 14 billion light years) a galaxy will be receding at a velocity greater than 300 000 km/s which is the speed of light. In which case any light it emitted today could never reach us. The Hubble sphere is an imaginary sphere centred on the Earth of radius 4,300 Mpc. If the Hubble parameter didn’t change over time, we could only see objects which emitted light today located inside the Hubble sphere.

Now what a strange coincidence! The distance in which the speed of the expansion of the universe reaches the speed of light is around 14 billion lightyears. The age of the universe according to the Big Bang hypotheses is more or less the same, i.e. 13.7 billion years. So for some strange reason we live today at the exact point of time when the last light of the Big Bang becomes invisible, because it passes the Hubble horizon.

If we had lived a few billion years earlier, the Big Bang would have been taken place well within the Hubble sphere and we could observe everything in all its glory. If we lived a few billion years later from now the Big Bang would have happened far beyond the Hubble sphere, and we would have no idea that it ever happened.

Luckily it happened exactly at the border of the Hubble sphere, so we can still observe it in Cosmic Background Radiation, which led to the estimate of the age of the universe being 13.7 billion years. This is an amazing coincidence considering the unimaginable time that the universe will exist and has already exited.

However I am not willing to believe in such statistically almost impossible coincidences. The only rational assumption is that the alleged age of the universe is an effect of the Hubble horizon. What we see in the cosmic background radiation has nothing to to with the alleged beginning of the universe, it's just the effect of the expansion of the universe reaching the speed of light (No the expansion of space cannot exceed the speed of light, it can only asymptotically approach it. Special Relativity remains valid here.). The universe is therefore either far older or, more likely, has no beginning at all. What appears to us as the Big Bang happening 13.7 billion lightyears away is nothing but the effect of the expansion of the universe reaching the speed of light and hereby compressing all the infinite universe beyond into the Hubble horizon. The Cosmic Microwave Background equivalent to a temperature of 2.7 K simply reflects the average energy of the universe. Since we can see the infinite universe compressed together at the Hubble horizon, it becomes so diffuse by the effects of Special Relativity that it becomes the CMB.

The Big Bang happening exactly 13.7 billion years ago is incompatible with the fact that the Hubble horizon is exactly the same, but derived from entirely different parameters. That kind of coincidences do not exist in the real world.
