Ah, good old Scientific Triumphalism! I thought it had mostly died out in this cynical age, but apparantly there are still some proponents.

You write:

Science is not a destination; it's not an Answer. Science is a means of travelling, so that you can find your own answers. Science is a journey.

Actually, science is not a means for finding your own answers. It is a means for everyone to come up with the same answers. Thus the need for testing and independant verification of results.

And in reality, while those who do science can be said to be on some sort of Journey Toward Truth, the rest of the folks who are not part of the scientific priesthood are supposed to "journey" by simply soaking up the popularized consensus of currently-fashionable theories, and then treating this popularization as "true" and somehow meaning something (until scientific fashion changes, and there's a new "truth" that one would be "ignorant" to not take seriously).

But yet, time and again new knowledge surfaces that directly contradicts a firmly entrenched religious dogma. The earth is round, the sun is the center of the solar system, the universe is older than 6000 years.

I don't know what religion you're referring to, unless it's a caricature of some flavor of Fundamentalist Christianity. Yes, you can find some (not all) Fundamentalists who will argue that a young-earth, literal 7x24-hour Creation is dogma. This has never been so for the majority of Christianity. In Catholicism, Orthodoxy, mainline Protestantism, and even much of Fundamentalism, none of the things you mention as "dogma" are, in fact, held as dogma.

The defining dogmas of Christianity are hardly secret, and are most completely summarized in the Nicene Creed. Here are the relevant lines from the Creed:

We believe in one God
the Father, the Almighty,
maker of heaven and earth,
of all that is, seen and unseen.

Hmm. Nothing in there about the earth being flat vs. round, or what revolves around what, or how long ago the Father did all of this.

Of course, in the spirit of scientific objectivity and inquiry, I expect you to not simply take my word for this, but to do your own investigation into the truth of this matter, and discover what is and is not dogma within Christianity. And, of course, to revise your opinion based upon the data you uncover that might contradict your presuppositions and prejudices. But I won't hold my breath in the meantime.

Science, on the other hand, discards the arrogance of religion. There is no dogma in science.

You then contradict yourself utterly by listing some pretty arrogant dogmas.

All things are knowable.

This is a humble attitude? As compared to the arrogance of saying "my reason is flawed and finite; I need Divine help to make sense of myself and the mysteries of life." You must mean different things by the words "humble" and "arrogant" than I'm used to.

Knowledge is colorblind

While I agree with this statement, I don't agree with the subtle ad hominem. Racism is not inherent to Christianity. "Here there cannot be Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free man, but Christ is all, and in all." (Colossians 3:11, RSV) Our saints, martyrs, and theologians have been of every race and color since the beginning of Christianity. Nor has science somehow magically been free of racism. Examples here are numerous, and the obvious one in this century invokes Godwin's Law, so I won't mention it.

The sense of wonder at the universe that you describe the the cornerstone of science! How great and wonderful is the universe! How great and wonderful the journey to try and understand it!

Indeed! It's so great that even a rationalist can hardly help but get caught up in it. :^)

I am mystified, however, by the idea that the "scientific" way of looking at the universe as a meaningless object that just happened to happen, and our understanding of that universe as a journey leading nowhere, should enhance one's sense of wonder, whilst the religious perspective that the journey has a destination, and that this universe did not simply happen, but is the work of a great Artist, would decrease one's sense of wonder at the marvelous world around us.

But scientists, who ought to know
Assure us that it must be so.
Oh, let us never, never doubt
What nobody is sure about.
-- Hilaire Belloc
