*You've asked that question many times and I've answered it many times, and 
my answer is always the same;  the claim is derived from the one and only 
assumption that Many Worlds makes, Schrodinger's Equation means what it 
says.  So far nobody has ever performed an experiment that disproves that 
assumption, if anybody ever does then Many Worlds is dead wrong.*

*Maybe. Maybe not. There is no doubt that mathematically the set of all 
possible curves is uncountably infinite, but we're talking about physics 
not mathematics, so the answer is not clear at all. There might be an 
uncountably infinite number of paths, there might be a countably infinite 
number of paths, there might only be an astronomical number to an 
astronomical power FINITE  number of paths; it all depends on if time 
and/or space is continuous or discrete. Schrodinger's Equation is an 
agnostic on that question, and so is Many Worlds.*

If the universe is spatially infinite, it must have begun as spatially 
infinite, since a finite rate of expansion, not matter how rapid, cannot 
result in spatially infinity if out Bubble has a finite age. But I have a 
problem with such an initial condition since it seems to contradict the BB 
by adding an additional singularity (to infinite density at T=0). What I 
can imagine is our Bubble emerging from a sub-universe (for want of a 
better name) which is, in fact, infinite in space and time. AG.
