Haha!! Yep!

I know! I screwed it up trying to post on my phone which I assumed logged me in automatically. I followed it up right away but it was on me to check. My own damned fault lol!

planethunters.org really is a great way to get involved though. Its mainly just registration, tutorials and getting to know the community but if you like the subject of exoplanets, its fun.

I wished I had been a little more calm when I wrote it. I concentrated too much on the lack of IR "glowing" observed and while its still not entirely accurate to say cometary dust doesn't put off infrared the main reason to be skeptical of the comet swarm hypothesis is that we just have no other examples of either such a large "swarm" of comets OR of any naturally occurring celectial body that blocks 22% of starlight. The largest gas giant planet would maybe obscure 2%. What really got me was the claim that NASA "concluded" the comet hypothesis as correct. They did no such thing.

Tyson makes the mistake of assuming Musks goals are the same as other commercial space ventures. From the very beginning - as in PayPal - Elon's stated goals were to prove that spaceflight could be much cheaper thereby forcing NASA into using its dollars better and getting humans to be viable on Mars. Period. He has stated these goals in speeches, books, talk shows and most importantly in investors meetings. All the people financing SpaceX when its not Musk's own money - share his goal. They are not in this for profit anymore than he is (yes, profit is desirable but only as it advances the other goal). His investors are eyes wide open when it comes to profitability. Its disappointing that Tyson either doesn't understand that or dismisses it.
