# The Uncertainty Principle and the 3-Body Problem

## Measurement Raises Uncertainty

Physicists have found some weird and wonderful aspects of the Universe over the years, none more so than the Uncertainty Principle. Simply it states if we try, at the same time, to measure the position and movement of a particle (let us say an atom), the more accurately we measure one aspect, say position, the other will become more inaccurate. As nothing stays the same then it is impossible to accurately know the current state of a particle, or a whole group of them.

## We Cannot Predict The Future

There are long held beliefs that if humans know everything about an object and measured all the surrounding influences then they could master and control the future of that object. It turns out that this is impossible.

To accurately predict the future of an object a repeatable result would play out each and every time without exception, or to put another way we would always get the same result. Thus it should be possible to describe it mathematically. Mathematics while as simple as 2 + 2 equalling 4, can also describe movement and increments of movement.

Early astronomers plotting the movement of the planets were joyed when their mathematics seemed to closely predict the movement of a single planet around the Sun (two bodies). The Sun and the planet in question act on each other due to gravity’s force on each other and the changing distances between them as they move.

'Perfect' Multiple Bodies |

When another planet was added to the system in these equations the mathematics did not work, observation did not match the mathematics. Thinking that it was a simple problem that would be solved later, the astronomers put the mathematics aside and basically ignored it. The excitement of believing they could predict everything overwhelmed scientific method.

## Hundreds of Years of Arrogance

But the problem did not go away and was not truly understood until centuries later. It was revealed that two body’s movement in isolation (which never truly happens) can be mathematically predicted, but when one or more bodies are added to the model, true accuracy disappears. It cannot be accurately predicted, and thus an element of uncertainty was introduced.

Whole generations of human thought were built on the falseness of predictability. Communism with its planned economies were built on this falsehood. The reality destroyed economies and many suffered.

## The Are Always More Than 2 Bodies Interacting

In fact in life all bodies interact with numerous other bodies so there is always an element of unpredictability in everything that happens, that is, things look similar but there are always subtle differences. This is the foundation of The Butterfly Effect.

## In Future Don't Always Be So Sure

So what does this mean for you? Again nothing, it has always been this way and always will be. Next time you are SURE something will happen, make an allowance for the chance that it may not happen.
