t seems that dark matter has distorted the minds of the experts, they are chasing ghosts. They are guessing that the shapes of galaxies have been distorted. Instead of just accepting what they see and trying to understand it they must apply their fictional dark matter. There are other simpler explanations than this. |

Do you even understand WHY scientists argue that dark matter exists? It's existence is implied by the laws of gravity. You really need to get over your anti-gravity viewpoint.

You're saying that all of mainstream science is TOTALLY wrong, that literally thousands of peer-reviewed papers are TOTALLY wrong, AND that almost all of the physicists and astronomers out there are delusional fools.
Do you have any idea how ridiculous this position is? It's MUCH more likely that one layman (you) is making a mistake than ALL of the experts being totally wrong. How can you believe that you, without a formal education in this stuff, know more about it than all of the experts???
Don't you see how arrogant that is? |

How does that differ from what you say about the peer reviewed papers of theologians? Don't you say that all Christians are TOTALLY wrong and delusional?

Two important differences:
1. Theology is not a science. There is no mechanism in theology that ensures that theological papers are true. By contrast, there is a STRONG mechanism in science to ensure that scientific papers are true.
2. I explain exactly where religious people (not just Christians) make their mistakes in reasoning. It's reasonable to come to the conclusion that a large group of people whose beliefs are not based on science and logic are wrong. It is NOT reasonable to come to the conclusion that a large group of people whose views ARE based on science and logic are wrong. |

No just 90% wrong when it comes to explaining anything related to gravity (dark matter's theoretical existence is only because of the appearant effects of gravity). If the effects that are actual observations can be explained by a simpler method than gravity then (according to Ockham razor) that simpler method is more likely.
Did you even see the picture on Astronomy picture of the day today? It shows a pin ball pathway for light which "causes" the distortions observed in certain galaxies. The real issue for me is first just what are the "distortions" and why do astronomers think what they see is an optically distorted phenomena rather than an actual observation of a non-distorted object (I would take this position.)
Astronomers are guessing that what they see is a distortion based upon what? Are their unsubstantiated impressions used or some actual standard based upon some objective method.
Even though Einstein was the one who proclaimed the idea of light being bent. He also didn't accept the idea of some "fabric of space" which is what seems to be happening according to the idea of when gravity "bends space/time." It is the entire matter when we talk about "black holes." Fabric indicates space is more like two dimensional rather than three dimensional. |
