Sending Gold Across realms

[Dupheadss]

Hey guys. I am just wondering what is the huge difference in the Value of gold across different realms...

To word it better...
Why is there such a huge differences in AH prices and just gold in general across the different realms?

and if there were to be a way to trade gold across realms how would you create a ratio ?
IE:
1g on Outland = 2g on Stormscale

Or would this destroy the realms economy ?

Sorry for all the questions!
Thanks

Not an expert in economics, but I know a fair share, it should just even out all the prices across servers.

Supply and demand.

You see that's interesting. I am just wondering how a gold farmer/seller would work out a ratio across the realms ? because the prices greatly differ from EU-US
There are slight differences among the realms but nothing too amazing.
