(1) I believe that Stephen Weinberg would disagree with much of it.

Remember that Hubble's Law was an uncredited rip-off of the prior work of LeMaitre, which Krauss actually has the chutzpah to (mis)quote. And LeMaitre WAS trying to prove the literal truth of Genesis at the time he met Hubble. His recantation (also quoted by Krauss) was much later, after Hubble had made LeMaitre's uncredited work famous.

You look at galactic red shift and see Doppler effect. I look at it and see multi-dimensional spacetime. The Sloan Deep Space Survey data supports my interpretation. It does not support yours, by orders of magnitude. As our instrumentation improves, Big Bang is showing big, ragged holes. That does not make it not true, but it certainly removes much of the smug certainty you display.

(2), (3) You are taking statements or assertions as settled fact.

Krauss admitted in the talk that we know absolutely nothing about Dark Matter and Dark Energy, other than as a patch to support the thesis that total energy is 0 and that the gravitational red shift is due to Doppler effect. That is not evidence, it is a mathematical contrivance.

(4) I don't know about that. I don't think Krauss is an atheist; I think he is a Kraussian.

My point was that charges of scientists having a Science Religion are often true. Behold this example.

The odd thing about Krauss's talk is that there are a lot of perfectly respectable cosmologists who would not agree with a single thing he said, using the same sets of evidence.

When you get right down to it, his whole theory is based on:

1) Assuming that the red shift of distant galaxies is due to Doppler effect. (There are other phenomena such as Minkowski spacetime that explain it just as well.)

2) In order to support his non-collapsing (flat) universe he has to postulate Dark Energy and Dark Matter, for which there is no direct experimental evidence at all. And he has positioned himself so that failure of the LHC to produce any will not embarrass him. Locked and loaded.

He talks glibly about all of this as though it were settled science, not open to other interpretations, nor to be questioned (at least he did not show any disclaimers in this talk) ins spite of the sparseness or even non-existence of observational evidence to back him up.

We have a word for that: RELIGION.

And I have no doubt that Richard Dawkins would defend him to the death out of friendship.

Wright admits he is a mystic.

Something about atheism leaves his mouth too dry or somethin'.

The list of famous atheists who have been willing to talk to him in interviews is impressive. He is not stupid by any means. And it is always interesting to see how the people he interviews (successfully, IMO) fend off his deism.

Go to: In conversation with... a computer program

LDmiller's Avatar Jump to comment 12 by LDmiller

This is a *really lame* simulation.

Years ago, there was "Eliza", and for my first Mac in 1985 there was a similar program called "Racter".

Both of those programs did much better than this! And that was nearly 25 years ago!

Maybe Darwin was Wrong in this case, It sure doesn't look like progress.

Or maybe it is a symptom of the dumbing down of humanity (including programmers).

I found the spam to meat ratio WAY too high on this. In spite of the woman's assets. Not enough Pinker.
