Lex, thanks again for bringing such interesting topics. Two comments. 1. dark matter -  how is it possible that no direct evidence of dark matter can be found if it makes up so much material in the universe.  With all the colliders and deep earth detectors, nothing has been found. Logic would dictate that the theory for dark matter is probably wrong and gravitational lensing is happening for other reasons.  2. big bang - don't buy it. If you are stuck in a box (inside the visible universe), how can you know what happened outside the box.  Am increasingly skeptic on mainstream science and politicization of... everything.
