Continuing Obfuscation

Brian Dempsey persists in his folly, in comments.

OK, Brian. You claim that SS1 cost five to ten million dollars per flight. So riddle me this: if Burt had decided to fly SS1 one more time, do you claim that he therefore would have had to come up with five to ten million dollars more to do so?

If so, why?

If not, then how much do you think that he would have had to come up with, and in that case, what was your original point, which was comparing SS1 cost to other suborbital vehicle costs (i.e., apples and kumquats). Wasn’t the intent of your mistaken posting to attempt to wrongly persuade people that SS1 is not a substantially cheaper vehicle to operate?

You may think that the difference between marginal and average costs is meaningless, but people who actual understand launch economics (and economics in general) do not.

Give It Up, Folks

This guy says we’re not going to colonize space.

Suffice it to say I find his “arguments” uncompelling, even if I were Catholic.

For one thing, he conflates advocates of space colonization with advocates of people looking for ET, as though the two things had anything to do with each other. He also deploys the foolish Antarctica analogy. He should stick to theology.

More On Born To Believe

Michael Novak writes about prayer. His example of Sartre is just more evidence for my thesis, I think. If I’ve ever prayed in my life, it was only as a very young (pre-school) child, and then only because I was told I was supposed to. I don’t ever recall any sense that there was anyone home when I did so, and I haven’t done so since the age of five or so.

As Jean-Paul Sartre wrote, he tried hard all his life to be a serious atheist, but even he felt himself breaking out in thanksgiving to God for certain beautiful days, certain stunning events. Of course, he then withdrew these “prayers,” but he quite recognized the naturalness of the impulse in himself. He wrote that being atheist is in practice much harder than many let on. One needs to stay on watch at every moment against little surrenders. The world so often seems “as if” there is a God.

Despite the fact that he reasoned himself into atheism, he was a natural-born believer. I’ve never felt an impulse such as that he describes, and the world has never seemed “as if” there is a God to me.

[Update a few minutes later]

Oh, and just to make clear, nothing in either of these two posts should be construed as an argument either for, or against, the existence of God. If God exists, He does so entirely independently of my, or anyone else’s beliefs about Him.

Errrr…unless, of course, you think that God exists for those who believe, and doesn’t for those who don’t. Which may actually be the closest thing to the truth.

Is The Age Of Carriers Over?

Could be.

Certainly, it’s very long in the tooth, and it lasted quite a bit longer than the age of battleships (the transition between the true was, arguably, abrupt, occurring on a quiet Sunday morning in Hawaii in early December 1941).

It will be interesting to see how new space capabilities start to trump conventional air power in the next few decades.
