How can you instantaneously split into two or more versions an 
*entire universe* with a radius of tens of billions of light years? 
How could the news propagate everywhere so quickly? But if it 
doesn't, if this is just a constrained bubble that spreads at c or 
slower, and attenuates by inverse square and chaotic rambles and 
stray quantum blurts, how can you say the *universe* has split?
