But to carve the Grand Canyon, Earth required millions of years. To excavate Meteor Crater, the universe, using a sixty-thousand-ton asteroid traveling upward of twenty miles per second, required a fraction of a second.

What would aliens say when told earthlings shift clocks twice a year to fool themselves into thinking there's more sunlight?

After 50 years of television, there's no other conclusion the aliens could draw, but that most humans are neurotic, death-hungry, dysfunctional idiots.

Do you realize that the 850 billion dollar bank bailout, that sum of money is greater than the entire 50 year running budget of NASA. And so when someone says, 'We don't have enough money for this space probe.' No, it's not that you don't have enough money. It's that the distribution of money that you're spending is warped in some way that you are removing the only thing that gives people something to dream about tomorrow.
