Re: Planet as large as its star (2009 June 3)
Please explain how this makes sense. Two objects are approximateley the same size. The compositions of the objects is similar. The hot one is ten times the mass of the small cool one. With gravity and the ideal gas law we have a problem. Bear in mind that, ignoring gravity and assuming both of thes...

Re: Planet as large as its star (2009 June 3)
Fusion is the theoretical result of greater density, not the cause of it. We are considering a red dwarf and a gas giant, not a white dwarf and a neutron star. The presence of fusion at the core should expand the outer layers of the star.

Re: 2009 April 21 - global warming
I can't take the time in this post to make the arguments and cite the evidence for the electrical nature of the solar system, I'll get to it. I'd advise against it. Discussion of the electric Universe, plasma cosmology, and other pseudoscience derived from the discredited work of Alfvén is grounds ...

Re: 2009 April 21 - global warming
In support of my argument that we really have at best an incomplete picture of the workings of the solar system and the earth, see this article that reveals that during its eruption, the (plasma) plume of MT Redoubt was rotating. This is probably an electrical phenomena. We will be forced eventuall...

Re: 2009 April 21 - global warming
Chris-for a very accomplished and successful man you have a hard time admitting when you are wrong. As when I quoted the model makers themselves. I think its a flaw in your character. You are a very slippery debater, not above quoting somebody's lonely study as gospel until you are called on it. So ...

Re: 2009 April 21 - global warming
During the previous AGW debate I made the point that models were estimations based on past data, I called them curve fitting, which they are. I also argued that with enough variables any curve can be fitted, but it wouldn't result in great predictive accuracy. Also that the models didn't take some i...

Check out the helical structure near the edge of the upper, outer band in the photo. Its almost as if it were a toroidal Birkland current.

Re: Climate Change Facts
The joke is on all the people who fail to have a full understanding of the science of climatology. I believe in global warming, but I also believe in global cooling. When you begin to remove the impact of the urban heat island effect from the global temperature data you will find that the global te...

Re: Haute Provence Star Trails (2009 March 14)
I don't wish to appear dense but, reading all the comments pertaining to the picture was very enlightening in regard to exposure but confusing with regard to the camera. Without knowing, it would seem a pinhole camera would be a equivalent to a normal lense. This image is not a fisheye but the disto...

Re: Iridium, Cosmos collision (APOD 2009 Feb 18)
The SBX X band ABM fire-control radar is stationed in Adak, it can track an object "the size of a baseball over San Francisco from the Chesapeak Bay." No reason to believe the Russians are too far behind. Size isn't the factor, but rather accuracy. And the radar fence system used to maint...

Re: Favorite APOD
Another favorite,due to its obvious bi-lateral symetry, resembling neither explosion or gravitational effects. The structure of the wings resemble nothing so much as a flowing glow mode plasma and Z pinch in the lab. Particularly the feathery ends of the inner sheaths. http://antwrp.gsfc.nasa.gov/ap...

Re: Iridium, Cosmos collision (APOD 2009 Feb 18)
I was under the impression Russian satellites are manueverable. If so, how do you know it was out of fuel? I woundn't discount the possibility of either side making a statement. The radar systems used by both countries for monitoring the majority of orbiting material are not accurate enough to be u...

Re: Antarctic Ice Shelf Vista (2009 Feb 15)
There is a deeper point about the nature of models. Every parameter is an estimate in the true sense of the word. If for instance, you were to examine albedo, you may write an equation that uses the earth's average albedo. Then you might get more sophisticated and vary the albedo by season or month ...

I have never seen a photo quite like this one. Why do the stars not follow parallel paths? Is it the focal length of the lens?
