Never presume that just because you disagree with an idea that you must be correct.

Scientific inquiry shouldn't stop just because a reasonable explanation has apparently been found.

Emotional truths woven by lawyers in the court of law are apparently more important than the truths of actual events. I have grown to fear for those whose innocence became trapped within the legal system.

We went to the moon and discovered Earth.

In the New Testament, Thomas Jefferson cut out everything that was mystical, magical, miracle - physically with scissors - and then pasted in all that remained, such as Jesus's Sermon on the Mount.

We in astrophysics we think of the universe all the time. So to us, Earth is just another planet. From a distance, it's a speck. And I'm convinced that if everyone had a cosmic perspective you wouldn't have legions of armies waging war on other people because someone would say, "Stop, look at the universe."

I'd like to live in a world where people embrace objective truths rather than be offended by them.
