 Thank you to Matthew for the question and Guillermo Pardo for that answer. So this question, like I said, has provoked quite the debate in the science unit. So if I'm allowed, I'm going to dig into this some more in detail for our sister show, Crowd Science. And I'm sure if we find out anything extra, we'll be back with fuller answers when we get them. In the meantime, if you have a question and the search engines of the world aren't giving you answers, why not try us?
