I did not understand why so many doubts !!! Just remember the *simple
math* definition of universe :
"the complete set of all".
So:
1. Doesn't matter if an object, even if abstract, is "something(t)" (time
variant) ... ( do not tell me there is anyone here who only conceive sets
of static concrete objects... )
2. If you can imagine anything *out of* such universe, defined in the
above way, you have not understood the definition...>> it is impossible "by
definition" !!! ( or so remember: which is the complementary set of the
universe? >> { } , the empty set...)
3. Any set is always a part of the universe (including { } and the
universe itself)...
Gomes.
PS1: sorry for the boring repetition of basic school notions... but...
PS2: the mathematical language is not just for mathematics... (sorry again
to those who already know the obviousness and importance of this...)
PS3: there are some concepts that instead of trying to adapt them to your
knowledge, first do adapt your knowledge to them... obs: it's not valid for
religious definitions... ;-|D !!
