Are you guys reving me up? If so I say this General Relativity is our best theory of gravity and that model suggests that there is unobservable matter out the which explains annomolies in the rotation curves of galaxies and various observation showing gravitational lensing... The observed expansion of the universe is consistant with the existence of an unseen energy which causes the expansion. Both dark matter and dark energy are consistant with the predictions of General Relativity. That is mainstream view at this time.. now honest injun..were you baiting me either of you..or Fred are you offerring critisism of mainstream without a new theory that may support the coyncerns you express..Alex
