The use of spirit as an explanation is basically and end of discourse. What I’m looking for is further discussion.
As CD said, dark matter is just one explanation for what we are observing. One other that occurs to me right now is, the deficiency of matter may explain our observation that the universe is expanding.
Quote:What we see as the galaxies being held together is really just a blink of the eye in the vast eons of the universe. So there may indeed be enough matter for that blink.
I don't understand what you mean - you would literally have to believe that there is no cosmic history and everything was created just now as it is including the light from the far past coming towards us looking as if all that history had played out, because without dark matter or an alternative, there is not enough gravity and galaxies and galaxy clusters would have all been torn apart by their rotation within several millions of years.
But there are enough independed lines of evidence for dark matter now anyways.They just should have called it differently. If it were called "Non-Baryonic pressureless component" or something similarly boring, people at least wouldn't think that it must be something terribly mysterious all the time. Imagine the press had called the Higgs Boson the God Particle or something stupid like that, we wouldn't hear the end if it! ... oh wait...
But like you and CD said, there is a balance of forces at work and dark matter is needed for both gravity and expansion.
The god who allows children to be raped out of respect for the free will choice of the rapist, but punishes gay men for engaging in mutually consensual sex couldn't possibly be responsible for an intelligently designed universe.
