Ultimate Law of the Universe:
Everything that "is" Must be in Equilibrium.
We can see that it isn’t.
This means if there is something, there is also something exactly opposite of it;
You mean that there is “the opposite of a lamppost”?
If there's a positive, there's a negative;
Apparently there isn’t – there is far more matter than anti-matter
If there's a cause, there is an affect. Without one, the other cannot exist.
Do you mean a perceivable effect (note spelling) or an absolute effect? If the latter, how would you show this?
To Further Explain:
Lack of equilibrium causes energy:
No, you have reversed cause and effect; you have not even reversed it well; one moment’s thought would show you are spouting meaningless drivel and you have failed to take into account that atoms possess energy even when at rest.
Equilibrium and Energy are the same thing,
No they are not, that is why there are separate words for them
because it takes energy to make equilibrium,
That is a meaningless statement
therefore: it's just transferring energy into equilibrium (which could not occur if they were already in equilibrium)
??? What?
This is the ultimate natural law, which cannot be broken.
Says you. And you are saying it by pulling it out your arse.
If it is broken somehow, It must be from a force that doesn't obey the laws of nature.
No, it would be from a force we do not, as yet, understand. BUT – your “ultimate natural law” is garbage.
You just say the first thing that enters your head, you have no evidence for anything you say, you haven’t thought anything through and, basically, you do not know what you are talking about.
This is just simply a theory, and I wanted to see if it had flaws...
OK, you’ve see it has. In fact it is so wrong that words fail me.
Thanks for your responses
