What is this law called? like of 50/50ish existence?

Question

i just answered some guys silly question with something like ...

cuz newton, the laws of physics, whatever dictate .. that no matter what you do in this realm, everything always balances out

there's no way around it .. you can't trick a mirror. boy's and girls are born at a 50 - 50 ratio ... you flip a coin 1000 times and you always get something close to 50/50

people are tricked into thinking one side can win due to wobble ... something wobbles one way a bit before correcting itself (balance) , the people think their side may win .. but only temporarily till balance is restored .. the only thing even close to peace

so otheres must have observed this, and the scenario must have a name

can someone tell me what that name is? like the "law of balance" or whatever

and if it's known to scientists and politicians (politics another example of 50/50ish party numbers), why don't they take more time to explain it to the general public ... people might actually then seek balance rather than absolute victory (which is only a temp fix)

i once watched WHOLE DOCUMENTARY EXPLAINING THAT symetry is the only thing that creates beauty (or balance)

Answer 1

its not a law its a observation.  its not a law because you can't use it to predict the future in given circumstance only a pattern that can be seen in retrospect. If a .300  ball player starts hitting .400 either he eventually goes back to hitting .300 and proves your theory or they start calling him a .400 ball player  

Answer 2

i dont know but i would like to now

Answer 3

symmetry

Answer 4

Some might call it the law of averages.  Others may call it equilibrium, as when hot and cold water are mixed and reach a single temperature.
