Scientific Facts

NASA's images from space are always amazing, for instance this crystal clear one from the Cassini spacecraft orbiting Saturn. It looks like you can reach right out and grab this moon. The whole scene sort of looks like it could be a work of art thrown on a potter's wheel from clay, the moon spattered with fliks for dramatic effect.

BUT have I mentioned I get more questioning as I get older? This wonderful Hubbel image of "Ring Galaxy AM 0644-741" below, is equally great, and I love to see the images, but I question the confident, settled and conclusive attitude of the descriptions of this kind of thing by the astronomers who write the copy.

Not to disparage the scientists, but the explanation is as if they are describing a ham sandwich, it is so certain. Oh, yes, this is 300 MILLION LIGHT YEARS AWAY, and is not even seen with visible light, and we have to reconsruct the data, but we are sure of everything. They casually state that these rings form in the collision of two galaxies, and USUALLY when this happens, the stars don't collide, and Rarely this and that yadda yadda yadda. Yeah, Right! Like they have seen many of these things occur in real time (millions of light years), and these are established scientific facts.

Excuse me, this is all very smart and logical scientific THEORY, not fact.

And the anthropologist knows the shape of an ancient man's flesh from two or three petrified skull fragments, and some leg bones, too. I've seen the sketches, so they must be true.
