I've learned quite a bit. I got the free version of Stellarium and Ive also learned that NASA is biased when the Esarth is in danger.
For instance, they can tell us everthing we want to know about the
Thermal Effects from Comet 2013 A1 (Siding Spring) on Mars’ Upper Atmosphere, but almost nothing about Ison, even when Comet Siding Spring is more than 3 times the distance away from us.
I learned that ~ if you really want to know what's going on ~ listen to the amateurs and not the professionals.
I see, so you didn’t learn that ISON was not a danger to earth, even though it really wasn’t. Sounds to me like you learned nothing.
