Whilst researching anti-gravity I came across a story I had read some time ago and it started me thinking;
Expanding Universe
An idea came to mind that may have little to back it up, but I just wondered what others thought of it.
We have heard about the mysterious "anti-gravity" like force that fuels the expansion of the universe, but I realised that there may be another explanation which does away with the need for a new force.
This is the idea that came to mind;
Quote:
Suppose our current understanding of gravity is good, but not quite right and in need of extension (a bit like the improvement of understanding Albert Einstein gave us from Newton’s laws of motion).
Now, if we consider what happens to gravity waves as they spread out through space, the conventional idea is they just get weaker until you cannot detect them. Since there is a parallel between gravity waves and electromagnetic radiation, it would seem logical that like EM radiation gravity waves go through some form of red shift.
That being true, is it not possible that when gravity waves are shifted beyond a certain point they no longer cause attraction between objects, but they then they then start to repel other objects. In other words gravity could it be possible that the force that is fueling the expansion of the univers is gravity itself ?

Well thats where I am going with the thoughts anyway. You may prefer to discuss the article, or steer the subject in a slightly different direction either way the expanding universe is an interesting topic.

p.s. I was in two minds as to which section to put this post in. As I have posted it here we should restrict replies to more mainstream science/astronomy.
