I would like to invite you all to speculate with me about steady state universe and the its problems. By steady state universe I mean the universe in which space does not expand (so this leaves out Hoyle's quasi steady state theory).
What would the universe be like, and what would be the biggest problems in this kind of theory?
I think that the biggest problem would be the need of "matter recycling system" (I think that there would be no matter creation), because without it all matter would become iron (wasn't iron the end-product of both fusion and fission?).
