Time travel in multiple universes

[Ben Goertzel]

Hi,   I recently wrote a blog entry on time travel   http://www.goertzel.org/blog/blog.htm   and Tom Buckner followed up with an interesting comment on the potential for time travel in Tegmarkian multiple universes.   (You can see it by going to the bottom of the page and clicking where it says "1 Comments.")   I am curious for any reactions to Buckner's comment by you multiple-universe experts ;-)   thanks Ben Goertzel
