Re: APOD: QR Codes: Not for Human Eyes (2011 Oct 04)
What does this have to do with astronomy, picture, or the day?

Re: APOD: Too Close to a Black Hole (2010 Dec 07)
"We have never seen them directly, yet we know they are there." Science is in a very sad state, as demonstrated by the quotation above. (First line of the movie.) The black hole is entirely an invention, made up to support other invented theories. The black hole had to be invented because...

There's no reason that the workings of the Universe have to make sense to us on some intuitive level. One of the axioms of science is that if the axioms are not true we can't know anything. You may be correct, but if you are then the universe runs on magic and/or religion and there is no point in p...

There are many stars and galaxies with tails, looking just like comets. Here is a star called Mira:

Good science doesn't depend on directly observing everything. There are lots of things we have never observed, such as the electron shell structure of atoms. But, like the geometry of the Universe, we observe other things that let us make inferences about things we can't see directly. Correct. The ...

Electric charges can cause all those effects, but apparently that possibility has not been considered yet. I understand storm fronts causing the buildup of electric charges, that happens enough here in Oklahoma. But electric charges causing storms? I don't understand this, please explain. Astronome...

How can an enviroment with little atmosphere contain or hold a storm or have a storm front? How can an eviroment with little atmosphere have a planet wide dust storm? In the images of the planet wide storm where is the storm front, how is it created? Where is the dust on the rovers? Electric charge...

HERE is a theory about that.
But we should remember that space does not have a temperature. Only mass can have temperature.

Another interesting question along that same venue Does the aircraft engine noise get quieter for the pilot given that he is moving faster than the sound waves that would normally reach him in the cockpit? Well, I'm just guessing here. No, the engine sound travels through the metal of the aircraft,...

It can be a real challenge to figure out if something has been observed or not. It is very common to compute what something ought to be and then go looking for it. There is a very real tendency to see what you are looking for even if it's not really there. And after seeing this face in the clouds th...

Maybe someone can explain something to me. Everyone seems to think a red moon is expected during an eclipse, even old hat. But when I saw one in the early 50s it was quite unexpected and it took a while for someone to figure out why it looked red. The newspaper said nobody had seen that effect befor...

I guess I understand the 4D universe concept as well as anybody, which is to say zero equals zero. I am very suspicious of any concept not based on observation, and this one is by definition not observable. And the Big Bang is based on the assumption that only gravity powers the universe. As soon as...

Why is the sky blue? (APOD 03 Sep 2007)
"The blue regions shine primarily by reflected light. Blue light from the star Rho Ophiuchi and nearby stars reflects more efficiently off this portion of the nebula than red light. The Earth's daytime sky appears blue for the same reason." http://antwrp.gsfc.nasa.gov/apod/ap070903.html W...
