It's too bad this went on a seemingly permanent hiatus, as I really enjoyed this series and I learned a great deal from it too. If you have any plans to revive it that would definitely be somehting I would be interested in and watch. I even have a slew of questions I could ask :)
Space has always fascinated me, and I have learned so much from your live chats, your Q&BA videos, even the questions from kids videos. Keep up the great work
wow i went to that webpage u talked about saying that those guys r really good.............as it turns out they r awfull atleast for me. U r much much much better in explaining and describing stuf. Thanks for your videos.
Hello Phil, Thanks for the awesome vids. I sent you an email w/ a question a while ago, donno whether it ever got through. I wanted to ask you, simply how do we determine distances: e.g. that a galaxy is a few light years away, vs. 80 or 100 million l.y. away vs. 13.2 Billion light years away. Furthermore, how are we able to tell that i.e. W Cephei is >1600X the Sun's diameter and would be 3000ly away. How can we be sure it is not in fact much closer and has a much smaller diameter?
If you have time for a short reply here in the form of a comment, that would be great. I do understand your time constraints too, whenever you can do that would be just fine. Again, thanks a lot for the wealth of info you keep providing.
Wow sorry to hear that the Q and A is gone even though you delete my comments from your blog. I'm glad you didn't accept my friend invitation because I would never have such snobby people as a friend. :-)
So I find you and your gone! Life is like this, Jer is a late to everything!!!! Really Looks good! Trust me you look fine in fron of the camera! And movie maker works but just tee's me off sometimes!
