Neil deGrasse Tyson is one of the most recognizable faces of science in the world, and for good reason. He has thought a lot about how to engage people in the wonder and joy of science, something that is also near and dear to my own heart, and to the spirit of many of my own activities, including The Origins Podcast. I was so happy that Neil agreed to return to have another dialogue on the podcast following the release of his new book, Starry Messenger, because it provided us with the opportunity to have the kind of give and take discussion that I so enjoy having with him, and which I also think is so important for people to get to watch. Neil and I share many of the same sensibilities but we don’t agree about everything, and our perspectives are sometimes different. We try to share those different perspectives with each other by respectful dialogue, and discussion. Sometimes we change each others’ minds, or at least I like to think we do.

That aspect of science, open questioning, joint enthusiasm for trying to find what he calls objective truth, and what I am less willing to label as such, is one of the things he discusses in his book, and I think our dialogue provides a great example of how science can help us move forward together toward a possibly brighter future.

It will be interesting to hear what you think about our discussion. In the end I hope you will find it as entertaining and informative as I did.
