Re: HUDF Infrared: Dawn of the Galaxies (2009 Dec 09)
The trouble with dark matter (or with its theoretical substitute by any other name) is that it walks like a duck but does not quack like a duck. You are half in trouble whatever you call it, but three syllables is a good limit for a term. That's why I'm 33% less excited about what we are calling dar...

Re: Solar System
I think everyone knows this is just an exercise. Right? --- Meanwhile, referring to contemporary commentary on Tethys, look at the Saturn system for methods of transporting material from one body to another. Saturn's moons and rings trade material like some people change underwear. As an exercise, s...

Re: HUDF Infrared: Dawn of the Galaxies (2009 Dec 09)
I thought the universe ceased to be opaque a few hundred thousand years after it began. So as I see it our remarkable point in history (though we've only occupied it recently) has lasted 13.3 billion years so far. Or does this lofty inspirational statement have a meaning I'm missing? save the sarca...

Re: Weird phenomenon over Norway
If the spiral is not photoshopped, I can only think that its appearance is from a time exposure of a laser projection, with the shutter luckily open for just the right interval. Well, forget that idea. I just saw the picture on what appeared to be video, not a still photograph, on the (NBC) evening...

Re: HUDF Infrared: Dawn of the Galaxies (2009 Dec 09)
we just happen to live at that specific point in the history of the universe where we can see that our specific point in the history of the universe is remarkable, because only at this point would we clearly see how the universe actually originated and is evolving.

redshft, bbt, dm, de, et al (split from HUDF Infrared)
Why do you think that a red-shifted expanding universe and Big Bang theories are the same idea? They are different things. You could have either one without the other. They fit together into a single model, but saying you don't like one because you don't like the other is arguing from an uninformed ...

Re: HUDF Infrared: Dawn of the Galaxies (2009 Dec 09)
Why do think red-shifted objects are red? All wavelengths become longer. Blue becomes green or yellow or red depending on the amount of shift. Green becomes yellow or red, ultraviolet becomes visible, visible becomes infrared, etc. You have to see the wavelength change for known lines in the spectru...

guess what I think of using fora instead of ... forums I agree with you, but my typing fingers act as if they were speaking out loud, and they apparently believe that fora rolls off the tongue and into the ear better.

Aha, another variable for geckzilla. If we fix it so only Mr. Robot can open a new topic, how can a topic be opened for an old APOD that never had a discussion of its own?
