Time will come when 
a diligent research 
and continuous 
clarify aspects that 
now remain hidden. 

The time-frame of a life, 
even if entirely devoted 
to study the sky, 
would not be enough 
to investigate 
an objective so huge... 

This knowledge 
will be achieved only 
through successive generations. 
Time will come when 
our descendants 
will be surprised 
that we did not know 
features as clear 
to them... 

Many discoveries 
are reserved 
for they will come 
when the memory of us 
will be erased. 


Our universe will be 
an unimportant subject, 
unless 
there is something in it 
to be investigated 
on each generation... 


The nature does not reveal 
its mysteries 
at once. 

(Seneca, first century)
