Comment 6 year old testimonial (Score 2) 187

my daughter (now seven) began using a 4.5" dob last winter. A member of the astronomy group that I belong to was pretty blown away that she could easily find the Orion Nebula on her own. She loves scanning the sky on her own and has stumbled across a few Messier objects this way. It's on the ground so it's almost immune to being knocked over. It's a fairly solid tube, so if it's knocked over it likely won't be a big deal. It has no moving parts, it's the perfect height for her, it's easy to move and the general 'point and shoot' nature makes it very easy to use. No batteries, no electronics, no alignment needed. (I collimate it once in a while and that takes all of 5 minutes) Also, the set up is ridiculously easy. I see her outgrowing this one day. There's a 12" truss dob waiting for her when she does.

Comment Soon be eradicated? (Score 2) 600

Sadly, this affliction is rampant in the USA. Happily, it is a dwindling number, and perhaps will soon be eradicated.

I wish you were right. I wish it was a dwindling problem, soon to be eradicated. I want to believe that. However, conservative Christians (which should make heads explode with paradox) aren't going away anytime soon. I think you are right that most Boomers that hold these beliefs will be departing in the next decade or so. But they have grandchildren, many of whom listen. I have been teaching middle school geography for ten years. This year was the very first time I had 2 sets of parents question my teaching of the Big Bang as they didn't believe it. I teach at a private school with intensely involved parents so this was not an issue of some parents just happen to start paying attention. While not a strong example, it does lead me to believe that the idea that Young Earth/ID types are fading away is simply not true.

Comment Speed of dark energy (Score 1) 142

What is the speed of dark energy? To go on and on about the speed of light, because we can see it seems to assume that we know something about the speed of dark energy. Assuming we know even one thing about dark energy seems a bit bold. I can only imagine our current fixation on c will sound like the ether to future physicists. Give us a few centuries and perhaps we'll be zipping around nicely (assuming we don't nucularize ourselves first)
