I was a physics major in college and the whole big bang theory never really worked out in my mind. The expansion isn't so straight forward. Why don't we see any effect of the expansion on a small scale? Gravity or electromagnetic forces might dwarf the expansion on small scales - but I would expect at least pertubations from our current theories...hmm, probably from quantum gravity too though - maybe they're really that small?
But it's too ill described as to definition of expansion. Is space a tangible thing? Is the expansion a wind like force? Or is it like a bunch of 'space molecules' where they all multiply at once? Again there's no expansion even in star clusters or within a galaxy. Must we not have a suitable description of space before we say it's 'expanding'?
I don't think people should stop trying to answer big questions like this, but I really dislike the sensationalism of it all. We don't have near enough information to make these judgements so why announce them as 'truth'? Selling newspapers? Funding research? Inspiring students? Maybe these are important things but it still makes me feel like science is becoming Entertainment Tonight or something.
