Interesting and troubling. Though I’m not entirely sure all of these questions were all that great. The big bang one, for instance, from my more recent reading on cosmology- if you are picturing an explosion like those seen here on Earth, you are probably picturing something not even close to what happened. Some of the people saying it wasn’t an explosion, may have an understanding of what happened that exceeds those who said it wasn’t. Simplicity is a virtue, but sometimes it is taken too far.
