It is difficult to find one theory that covers all the different observations that has been done, and which is based on the common knowlegde that exist "today" of our nature and our universe. If we split the observations in different fields, and say that they have nothing to do with each other, it might be possible to discuss possible explanations on some of these fields.

To find a solution of the phenomena, it is important that several scientific communities take part in the work and discussion.
