Lol!
In other words, they really don't have a clue what reality is. There is a popularly accepted "multi-universe" solution within both cosmology and quantum mechanics, the "Many Worlds" hypothesis for QM and this one discussed here for cosmology, a field that deals with the "big picture", expanding universe, etc. It is extremely unlikely that both, if either, of these apparently unrelated realities can be true.
In any case, I wish it were true ("infinite realities"), because then there would be at least some hope of escaping this one and entering one where there are no liberals and no 'president obama'.
Or one where everyone looks like Obama...
