Pros: Mars is exotic, romantic. Cons: It's cold, barren and can't even breathe.
"It’s OK to be wrong as long as you learn from your mistakes."
"Knock yourselves out, but this is a big problem and it’s not going to go away.”
The science guy says the party needs to expand its outreach, and Donald Trump certainly isn't helping.
Bill Nye and others say it's time to tackle the stigmatization of nonbelievers.
He's making a habit of staking his claim for science.
"Do not misrepresent NASA. Fossil fuels are not cooling the planet."
"Bill Nye is as much a scientist as I am."
Not everyone's pleased about it, though.
