Olli S, i genuinely hope that you hang around, because you do seem to have a legitimate interest and the purpose of this board is primarily to educate. However, holding a position in defiance of evidence to the contrary is dogma, not science. That is going to be challenged in any scientific forum.
If you are still reading, I would like to throw one more item into the mix. You are having difficulty accepting that space might expand, because it runs counter to what you regard as 'common sense' - no one has any personal experience with "space" expanding, you can't imagine what could possibly be happening to cause such a thing.
You may be interested then to read up about the Casimir Effect. First developed as a theory in the 1940's and with experimentation confirming predictions in the 1990's, it is best described by the quantum mechanics effect of virtual particles. The concept of virtual particles runs directly against common sense - is our day to day experience, something either is, or it is not. But anyone can run an experiment in a laboratory here in Australia, or in Europe, or America or the moon that will show that the effects predicted by Casimir are very real indeed.
Now, if I argue that the non-existence of quantum mechanics is a "rational fact" because my day to day experience of the world around me doesn't operate 'that way', then I need to come up with an explanation for the Casimir effect that is also consistent with the entirely of observations (and the very real technological advances made using QM).
If you argue that the non-existence of the expansion of space is a "rational fact" because that's your day to day experience of the world around you, then you need to come up with an explanation for the redshift effect that is also consistent with the entirely of observations.
Until we can, our arguments would be dogma, not science.
