How You Can Disprove Sarah Palin by Just Looking at the Sky

by Len Hart, The Existentialist Cowboy

Sarah Palin is a "young Earther" who believes in a Biblical young universe, created by God just 6,000 years ago. Much longer ago was the beginning of a vast migration of an African tribe out of Africa, into Asia and eventually across the Bering Straits into Alaska enroute to what is now called the United States. (No --Sarah Palin did not see them coming from her front porch.) It is hard to imagine how they managed to begin or complete this journey if the universe had not yet been created!

As they passed through Sarah Palin's back yard, she was not at home! She may still be "out to lunch". She would not be conceived and born for at least another 30,000 years give or take a thousand. In this period of time, wolves --and nature of which they are a part --did just fine without her, without GOP fairy tales and/or lies about almost everything --science, economics, ethics, the age of the Earth and the greater universe of which Earth is but a tiny, tiny part.

Palin is proven wrong whenever we look up at night and see ANDROMEDA --the nearest Galaxy to Earth. No observatory is required. Andromeda is the only galaxy that may be visible to us via the "naked eye". It is but a mere 2.5 million light-years (2.4×1019 km) from Earth. Every other Galaxy is much farther away.

This is direct, observable, provable evidence that shatters the kooky, fundamentalist belief that God made earth and universe over a period of just six days 6,000 years ago.
Andromeda Galaxy, named for the mythological princess Andromeda, is the nearest spiral galaxy to our own Milky Way. It is the largest galaxy in what is called the "local group" which also contains the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies.

The Andromeda Galaxy is the most distant object visible to the naked eye. Merely seeing it disproves Palin. The light from many galaxies seen in this "deep field" photograph began its journey to earth several billion years ago. Each photon from any star in any galaxy that appears in this photo disproves, if not rebukes, Sarah Palin's insistence on a fairy tale if it is not a lie.

Any object more distant than a mere 6,000 light years is enough to disprove Palin and her anti-science, anti-smart, pro-ignorant, pro-stupid sponsors and constituency. Images from our orbiting cameras --like Hubble --are stunning --a vast star field in which almost every object is a galaxy. See the photo at right. Every object in this photo is much, much more distant than Andromeda. Every object in the "deep field" disproves Palin.

Recently, "we" photographed the most distant "object/event" --the "Big Bang" itself! This object is some 13.7 billion light years distant. It has taken light from that "object" 13.7 billion years to reach Earth. This development exposes Palin's psuedo science and/or superstition is MACS0647-JD which may be the farthest known galaxy from Earth at some 13.7 billion light-years distant! The Universe, then, is at least 13.7 billion years old.

Creationist B.S. Exposed

by Len Hart, The Existentialist Cowboy

Richard Dawkins was recently issued a challenge --disprove creationism in one sentence. I can do that myself. Here it is: if we can see Andromeda --some 2.5 MILLION light years distant from earth --then creationism is false!

Andromeda can be seen even with the naked eye; in any case, it takes light from Andromeda some 2.5 MILLION light years to get here and be seen. That we can see these objects with or without telescopes utterly disproves creationism and a 'young Earth' or young universe.

I chose Andromeda because it is accessible, close enough to be seen with a good pair of binoculars, perhaps, even, with the naked eye. I saw Andromeda as a kid with a pair of hand-me-down 7x35 binoculars duct-tape to a shaky tripod. Deep space images from the Hubble are, of course, state of the art and much more dramatic. Galaxies some 17 BILLION light years distant prove that the Universe is considerably older than Sarah Palin's idiotic concept that homo sapien co-existed with dinosaurs a mere 6000 years ago.

Astronomy mag has an excellent article about how distances are determined. And the speed of light is a universal constant. [See: The Michelson-Morley Experiment. Michael Fowler, Univ. Va. Physics 9/15/08. ] These are not 'assumptions'. This is established, empirical science.

That issue is settled --the speed of light is not an assumption but a proven empirical fact! And so too are the distances to nebulae and galaxies much farther distant than Andromeda.
There are likely to be galaxies that formed slightly earlier, which so far we haven't been able to detect because they are so faint and distant.

However if we look back too far in time, there's simply no stars and galaxies to look at — after the Big Bang, it would have taken a few hundred million years for matter to clump together with sufficient density for stars and galaxies to form.

So if more powerful telescopes can't enable us to see any further into the universe why are we still building them?

Lomb says larger telescopes will be more sensitive and enable us to look into the past of the universe more clearly.

"There's still the great mysteries of what happened between 13.7 and 13 billion years ago," he says.

--What is the most distant galaxy a telescope can detect?

Below is the Hubble Deep Space photo. Every galaxy in the photo disproves Sarah Palin's 6000 year old universe.

Pick a galaxy at random. Imagine that you are an intelligent being living on a planet -- just one of a multitude of 'solar systems' that most certainly exist in this vast cosmos! Imagine that you have struggled with the concept that should your civilization develop craft capable of near light speed, it may yet take a million or more lifetimes to reach our own galaxy --the Milky Way and, when reaching it, 100,000 additional years to traverse it!
