Well well, if you step outside the box, realize that all efforts thus far have been proven to be wrong, then you might just come up with some wacky idea that is more plausible than anything thought of so far. I like this Petr Hořava guy. He basically said BUNK to classically accepted theories and tried something radically different. And what do ya know, it's starting to look rather promising.
You can get the details from the article. I'm not going to rewrite it. Suffice to say, I LOVE it when people challenge scientific dogma and take the risk of looking like an idiot on a hunch that what they've thought of might actually be valid. There aren't enough risk takers anymore in the scientific community, and there are far too many people who are so absolutely entrenched in faithfully following what they've learned in school that they've lost their ability to question even the basics in the hopes of maybe...just maybe...making a startling discovery.
Will this new idea pan out? Who knows. It looks good so far, even with its bugs. Still, at least Petr is humble enough to admit he's not perfect and that he hopes people will tweak and refine his theory. Can't say the same for so many scientists who stick to their pet theories to passionately they consider it fact.
I personally hope it does pan out, because then we can put this dark matter/energy bunk to rest. :)
