I had the set of all possible universes in mind. But, as I wrote earlier (in
August), the set of all possible universes is contained in the MWI. The
reason is that there is a nonzero probability that you are be simulated by a
computer. This computer could run any program.

I can't see this. For one thing, you can't 'travel' to other universes
with
different laws of physics, at least not according to the MWI. More to the
point,
assuming quantum suicide works, you will find yourself in one of the sheaf
of
universes which has split off from the one you started in. This is true
anyway,
according to MWI, but if you also use quantum suicide you limit your
existence
to a small subset of that sheaf (the subset in which you won the lottery,
for
example). Since you only experience universes which are physically
possible
continuers of the universe you started in, you keep the same laws of
physics.
So - you can't journey to a universe in which the laws of physics are X by
using
quantum suicide to select versions of yourself for which X is true; you
can only
limit your existence to universes in which X happens to be true.
Always assuming that quantum suicide actually works (as Larry Niven
said
about the matter transmitter which destroys you at point A and creates a
perfect
copy at point B, I wouldn't ride in the damn thing).

Subject: Travelling to a different universe
Suppose that every week I subject myself to a suicide experiment. I use
a
suicide machine to win that weeks lottery. After a few years I will have
won
hundreds of times in succession.
Now there exists a class of universes, with a very low measure, in
which the
laws of physics are such that I am guaranteed to win. The probability that
I
find myself in such a universe will have increased substantially after
each
experiment. After a few years I will be sure to live in such a universe.
It
would be easy to check, all I would have to do is to buy a ticket and see
if I
have won without using the suicide machine.
