I have read that the expansion of the universe is not a relative velocity and therefore not restricted to the limitation of the speed of light. I read that this creates a horizon which we cannot see beyond due the fact that the portions of the universe are moving away from us at a speed greater than the speed of light. I accepted this when I first read it, although I was surprised, but now, thinking about it more, I am seeing logical contradictions and beginning to suspect that this was misinformation. I believe that simply an accelerating expansion would create a horizon even though there is no relative velocity, due to the expansion, which exceeds the speed of light. So I don't think the existence of a horizon is sufficient to support the idea that any relative velocity due to the expansion can exceed the speed of light. My difficulty is that I cannot see any logical difference between a relative velocity due to the expansion of the universe and a relative veocity discussed in special relativity. I imagine a space ship leaving a galaxy towards another at relativistic speeds and wonder how to calculate the relative speed towards this target galaxy if it is receding from the starting galaxy, especially if this recession can accelerate to something beyond the speed of light. In fact the whole idea of an expansion which is exempt from special relativity implies to me some sort of priviledged refrence frame which distinguishes the relative velocity due to expansion from a relative velocity which is not due to expansion. So I hope you guys which are more educated in general relativity that I am can clear this up for me. And if you can do this then maybe you can address the further topic of the superluminal expansion of the galaxy in the cosmological theory of inflation.
