* 5% "ordinary", baryonic matter <-- all now accounted for
* 27% dark matter
* 68% dark energy
Second, I don't think it's embarassing. I think the other explanations if it does _not_ exist are even more convoluted. At least the dark matter idea is only saying there is stuff that interacts poorly with other matter. That doesn't sound all too crazy as explanations like "despite all extremely precise evidence, theory of gravity must still be somehow wrong on larger scales!!" to me (math is not exactly known for sudden special cases), or having to create all new specific theories on why something else must be at play on a cosmic scale than simply (yes, simply) a dumb weakly interacting particle.
