I'd say its advanced high school or college... but, that is the nature of the material. It is not a simple subject matter, and I recommend you know the basics of relativity before reading it.

And matt... that is the logic of those who are much wiser than I. I'm guessing its because its either impossible or extremely difficult to prove the nature of the cosmos....... plus, as I said, if the universe was accelerating or decelerating, the effects would be obvious. Since they aren't, it isn't happening. In addition, the reason that the universe ISN'T decelerating is from the initial force of the Big Bang. That is the force that is counter-acting gravity.

While your guess is a decent idea, it is in clear violation of the laws of physics.

As I said, it is accepted by the greatest minds in this field that the universe is not accelerating or decelerating. The reason as to WHY is what they all can't prove. And again, I feel, as do others wiser than myself, that FttSoL is the best explanation as to WHY, even though it violates the most time old principle of physics, a constant speed of light. Then again, he only says that there was a VSL in the nanoseconds after the Big Band, after which light slowed down to what we now know it as. Only through the VSL does the current nature of the universe make sense. The tight-rope walker example is not mine, its from the book.
