Dr. Neil deGrasse Tyson, TV host and probably the world’s best-known astrophysicist, is scheduled as a keynote speaker at the 2014 PLUS Conference, November 5-7 in Las Vegas.

Recently we at PLUS Blog had the chance to chat with Dr. Tyson about the universe, his personal philosophies and other topics that we found interesting. In case you missed it, you can check out the previous interview clips here.

In our new clip for this week, we ask Dr. Tyson:

Thanks to Minneapolis school teacher Eduardo Romo for suggesting this question.
