nevyn - Mainstream science does not claim infallibility - though sometimes (as with the evolution vs. creation debate) some scientists will state things as fact which are not proven and should indeed be challenged.<br /><br />Astronomers tend to be more humble than evolutionists and creationists - often admitting what they state as a correct model now may be changed quite drastically in the future.<br /><br />I would like to address your challenge of the law of conservation of matter and energy.<br /><br />I believe in said law, btw.<br /><br />Your point on there being no such thing as a closed system is not accurate but it is an excellent point.<br /><br />Scientists often assume our universe is a closed system - and in many ways it is. <br /><br />However, assuming dark energy is from within is one problem with this belief. <br /><br />It is better to keep an open mind and consider the possibility that the expansion of our universe, and the acceleration of expansion, may be evidence our universe is not totally a closed system - thermodynamically speaking.<br /><br />In short - it is good to question provided one is really interested in finding truth, finding accurate answers.<br /><br />Back to that law of conservation of matter and energy - all observations support this (contrast evolution vs creation where both sides cite obersvations in support of their favored model).<br /><br />However, and this is why your point is a good point: we do not directly observe the cause and effect mechanism involving the propagation of dark energy.<br /><br />Or gravity for that matter.<br /><br />We do not fully appreciate the gravity of the matter!<br /><br />[My sense of humor gravitates in.]
