Starship Asterisk*

Please someone find a fix! I'm addicted now and I'm having to go cold turkey.

I watched the first five, and was looking forward to the sixth tonight. What happened? I can't find how to download except through itunes. Did learnoutloud renege on the deal? What's going on? If they took it down, at least they should have noted on the page what happened. =( I'm very upset with the...

Did I miss the vote? I'm in favor of less moderation. Over-moderating kills a forum. That's my humble opinion, for what it's worth. =)

I think it's cool that this site educates people about astronomy, and people who read it every day over time end up understanding a whole lot more about the universe.

Dark matter doesn't interact with normal matter except through gravity . (Just thought I'd clarify.) The picture shows where dark matter has to be to give us the gravitational lensing effects we observe. The interesting thing is that when the galaxies collide, the dark matter just slips right throug...

Cats actually have it all figured out.

I'm enjoying the course a lot! Thanks for making it free and online. I think all courses should be like this, to the extent possible. I'd expect all humans to be interested in this course just to understand a little more about the neighborhood we live in, the universe in which we find ourselves. Is ...
