One thing is that so far most types of energy relationships have been figured out. Check this wikipedia article as a starting point. The odd man out of all the equations is gravity. We can predict it’s effects on the large scale but it still doesn’t quite make sense smaller down.

The pattern matching in your head that sees similarities between galaxies and atoms is nostalgic but cosmology involves lots and lots of math and there’s no theories on the books right now that would suggest anything more then 5 types of forces and even then the 5th one is mostly people trying to explain why the light goes off when you shut the fridge by suggesting something in the fridge must go flip the switch.

There is actually a pretty interesting similarity between money flow and physics. The quantum version of money would be like tracking every transaction and every penny in all the peoples pockets in all the world. You woulnd’t know for sure if someone would choose pepsi or coke , but you could say reliably he’ll get a drink.

Relativity would look at national budgets, trade deficits and mega corporations. It would reliably predict which companies would go up or down in value, future stock price and so on.

The problem of course is you can’t tell if the US dollar will rise against the japanese yen but measureing every cash register in the world. Or more accurately if it can be done we’re not aware of how it can be done. Similarly looking at corn prices in the US vs China won’t help you predict if joe blow will buy a can of creamed corn for dinner.

One of the major goals of science and economics is to figure out the ONE equation you can use to compute big and small values.

Now as far as the infinite amount up or down that’s something we’re pretty sure isn’t happening. Again with the money model… it would be like noticing we don’t see any money smaller then pennies and we don’t see any money / spending bigger then country and corporate level spending with the occasional billionaire for estimates. There’s no larger source of money coming from the moon or Mars – we are pretty solid on the upper and lower end of the scale.

So if you can come up with a formula to show how your decision to purchase skittles for lunch affects the price of 3 speed bicycles in china and it’s right, or how the us dollar vs indian ruppee predicts if you’ll buy a bag of m&ms instead – then you’ve got a good idea about what physicists are trying to accomplish. Rocket science look easy by comparison.
