This is why I'm tired of this science vs. religion culture war bullshit. The imagined necessity of fighting this fake war makes everything else subservient to it so that a boring nerd can't even imagine something fun to do with time travel, he just wants to go back in time and prove there was no Moses.
On another note, the method of time travel he proposes isn't as new as he thinks; Arthur C. Clarke did a whole novel about it.
If we can call homophobes closet homosexuals without irony, I think these types of scientists are closet creationists. Also, his sci-fi world of the most boring time travel device ever blows. No scientist is going to wait until the 25th century to see the Big Bang through his website. 976-EVIL was more plausible.
