Science is not a subject you took in school. It's life. We are wrapped by it, in it, with it.

Americans live in a free country, which allows you to believe what you want. Because you think that something is true does not require that it is objectively true. The value of science concerning itself with objective truths is that we can make decisions and statements that affect everyone, which is why legislation really should be based on objective truths, not what is going on in your head.

Today, scientists sound the alarm on other environmental dangers. Vested interests still hire their own scientists to confuse the issue. But in the end, nature, will not be fooled.

But my vote for Venus's most peculiar feature is the presence of craters that are all relatively young and uniformly distributed over its surface. This innocuous-sounding feature implicates a single planetwide catastrophe that reset the cratering clock... turning Venus's entire surface into the American automotive dream-a totally paved planet.

If cosmological theory were dominated by women, who are no strangers to cycles, how can we know for sure that we wouldn't then be told that the oscillating universe is the more aesthetically fulfilling alternative?

I like seeing how people have succeeded when others would have presumed they would have failed, and others just go along with whatever everyone else does.

The chunks of comet Shoemaker-Levy 9 were so large, and were moving so fast, that each hit Jupiter with at least the equivalent energy of the dinosaur-killing collision between Earth and an asteroid 65 million years ago. Whatever damage Jupiter sustained, one thing is for sure: it's got no dinosaurs left.
