Hello(adsbygoogle = window.adsbygoogle || []).push({});

I have recently read an article about tensor vector scaler theories (Te VeS), including John Moffats STVG and Philip Mannheim's "conformal gravity", available at

http://physicsweb.org/articles/world/19/6/5/1

I understand that Newtonian-Einstein gravity works very well across a broad range of scales and that it should not be written off just yet. And that these ideas are still very theoretical and may prove to be just that, ideas! However i find the idea of 'doing without' (my term) dark matter and dark energy as appealing if not simple solutions to cosmolical problems such as expansion rates.

I have four questions,

1) Please can someone explain to me (layman) what a 'phion field' is?

2) How in nature would such a field be formed? and what action would drive it?

3) What is a fourth order "Weyl tensor"?

4) How much experimental evidence is there for the existance of DM and DE.

4) I would also be interested in hearing your thoughts on these theories, are they worthy of pursut? and do you think they will yield any fruitful results?

Thank you for your input, i may have more questions as the thread evolves.
