Just incase someone is wondring.my post was sarcastic. I treated it more of a joke then a refuation.
The author is quite arrogant and doesn't really understand cosmology.
The horizan problem is solved by alan guth's inflation modle.
I was acctuly having a chat about it with one of my friends who is an astro-physicist and this is what she had to say.
"In other words, for this galaxy to lie 13 billion light-years away from Earth only 750 million years after the Big Bang, it would have had to travel 13 billion light years in just 750 million years' time. That requires the galaxy in question to travel more than 17 times faster than the speed of light, a speed limit which according to the Big Bang supporters was in effect from the moment the universe was 3 seconds old."
He has no idea about how a light year is used. In reality it is the light travel time from an object. When an object is said to be 13 billion light years away, that is how long the light has taken to reach Earth, not it's true distance which the case of such an object would have it at about 39 billion lights years away in distance today. When you see an object in space you are seeing at it was how ever many years ago, in the place it was that many years ago. It also produces some very strange paradoxes, take Betelgeuse, beta-orionis, its about 450 light years away, and if it has gone nova, say 150 years ago, it'll be another 300 years till we know. So therefore we're looking at a star that no longer exists.
There are two things to realise about the universe. First there is what is known as the, observable universe, and the true universe. The observable universe is pretty self explanatory, it contains everything within the universe that we can see and extends out to about 13.75 billion light years, the age of the universe. The true size of the universe is about 3 times the size of the observable universe, (3 x 13.75 = 41.25 (+2 to 3%)) The cosmological horizon is at about 43 billion light years beyond which we will never be able to see directly.
As for his comments on the CMB, that just shows he knows nothing about it. Even though it looks very variable, there is not that much difference overall between two points on it. Overall there is a 0.25K difference between the hottest part and the coolest part.
