Or you could watch the chat and ask him yourself. You would need the proper email address, or a You Tube account, so a heads up there.
Chris has a weekly live You Tube chat, and he answered my question and I didn't feel like he had any bit of arrogance, or anything like that. Someone asked him what space smells like. I was like He took the question seriously and respectfully.
You guys and girls here are brilliant, and I would love to hear if you have any questions. It would be fun I think.
I plan to watch him every time for the next few weeks, because I do learn things, as well as solidify what I already know.
Is anyone interested in asking Chris a question? I think he does a fine job explaining things to the audience imo.
