the reason we don’t have time travelers is that the past is no more concrete than the future. [Current science disagrees with the idea that] just like there are infinite potential futures, there are an infinity of potential pasts that could have evolved into the present [instead insisting that the entire past is fully embedded in the present]. [It’s not supported by any current theories that] the probability of reaching a particular past is essentially zero.

I vehemently disagree with many worlds theory. I think its a total mindfuck. However I do think that the future influences the present and the past.
Looks like somebody has read Anathem.
