I thought we'd be talking alternate universes and QPU alignment

To boil it down, a statement can be true or false (which are self explanatory).
However, the idea adds in the properties of possible, or contingent truth value.

One classic example is, while it is contingently true that Aristotle was the teacher of Alexander, on a possible world (just think of it similar to an alternate dimension) perhaps Aristotle died when he was a baby, so he could not of been the teacher of Alexander.

However, while certain things may vary by what could of been, certain things are argued to be necessarily true, i.e. 2+2 will always equal 4, a triangle will have 3 sides, the husbands of widowers are dead, and etc.

This is a grounds by which some argue if a thing is necessarily exists (HAS to), or contingently (only for us).

QPU is pretty complex.

>the husbands of widowers are dead
Only when gay.

y-you know what i mean

>y-you know what i mean
And now you're against gay marriage?

But do the things from dimensions others than mine actual one actually exist?

please stop bullying me

it's more of a thought experiment to judge where on the scale of necessity a thing may or nay not exist

>Another thought experiment
I adore analytical philosophy, but there are way too much of those.

Anyway, if so, I fail to see a novelty in it, the very same thing's been discussed by Leibniz anyway.
