Imagine a powerful being of your choice casting this spell on Earth:
- Earth can hold only 8 billion people
- If a child is being born and this child breaks the 8 billion rule, this happens:
- Wait 30 minutes. If someone else dies in this time, then everything is OK
- If not, take every human older than 32 minutes, and randomly kill one
If step 4 happens, such a person always dies by a sudden heart attack. If they cannot have a heart attack, they simply stop breathing. If they cannot stop breathing, their brain will simply stop working.
22:00:00.000 UTC: Earth population: 8.000.000.000 people, waiting... 22:00:00.015 UTC: Live child (A) is being born in Pakistan 22:15:00.389 UTC: Live child (B) is being born in USA 22:25:13.618 UTC: Someone in Mongolia dies of age. Child A is resolved, Child B still pending 22:32:00.015 UTC: Treshold for Child A, it can be given to random pool 22:45:00.389 UTC: Child B is still unresolved, start random search... 22:45:00.390 UTC: A hunter in Siberia gets heart attack and dies 22:45:00.391 UTC: Earth population: 8.000.000.000 people, waiting... 22:50:05.850 UTC: Plane crashes in China. 190 people dead. Next 190 children can be born without killing anyone extra
For the scope of this question:
Alive == Brain activity.
Dead == no brain activity.
So if someone manages to survive a heart attack AND lung failure, their brain will simply shut off. So, you can keep their body "alive", but take for granted that such a person will never wake up (and they are taken out from the Earth random pool, because they are dead).
The question: Will humanity ever find out that such a rule is in place?
It is estimated, that we will hit 8 billion people milestone by the year 2026.
I know it is safe to assume that in (say) the next 10 year, people will somewhat realise that something weird goes on. But will they be able to pick this magical link?
And what would help them to do so? Do I have to create an alternate Earth, where there is more magic than just this one?
