Astronomy is certainly not a field about which I know much more than what I learned in high school (and later on my own, reading here and there). It took me a while to grasp what was going on, and I thank you for the links to the other articles you wrote, especially the ones in Forbes.
Even if Dr. Loeb has a point (which, as you explain, is unlikely), he should have made it respectfully and in a different manner. His attitude and tone made for an awkwards exchange; the content of what was trying to be discussed gets completely lost because of the way it's presented. Kudos to Dr. Tarter.
Oh, and also... please don't hold my first name against me. Not all Avis are the same. ; )
