One you see the table there another you sees the table here

The theory that describes atoms and their constituents 
is quantum mechanics. It is hugely successful. It has led to computers, 
lasers and nuclear reactors,  

But quantum theory also tells us something very disturbing about atoms 
and their like: they can be in many places at once. But how is it that atoms 
can be in many places at once whereas big things made out of atoms - 
SAY tables, trees and pencils-apparently cannot? 

Reconciling the difference between the microscopic and the macroscopic is 
the central problem in quantum theory.The many worlds interpretation is one 
way to do it. This idea was proposed by Princeton graduate student 
Hugh Everett III in 1957. According to many worlds, quantum theory doesn’t 
just apply to atoms, says David Deutsch. 
“The world of tables is exactly the same as the world of atoms.”                                      
But surely this means tables can be in many places at once. 

But nobody has ever seen such a schizophrenic thing/table. 
Answer:  FOR THE table TO BE IN two places at once, there are also two 
versions of you - one that sees the table in one place and one that sees it in another place.
SACRE BLEU!  THE consequences OF THIS are remarkable, ARE THEY NOT?
IT MEANS  A universe must exist for every physical possibility.
It means everything is possible, ie dinosaurs survived, evolved 
and are reading this. In another parallel universe of course.  Sacre bleu! Mon dieu!
